32f1f622 | 5 | Changes between 0.9.8g and 0.9.8h [xx XXX xxxx] |
2339c5d7 | 6 | |
9e7459fc DSH |
7 | *) Add utility functions to handle ASN1 structures. ASN1_STRING_set0(): |
8 | sets string data without copying. X509_ALGOR_set0() and | |
9 | X509_ALGOR_get0(): set and retrieve X509_ALGOR (AlgorithmIdentifier) | |
10 | data. Attribute function X509at_get0_data_by_OBJ(): retrieves data | |
11 | from an X509_ATTRIBUTE structure optionally checking it occurs only | |
12 | once. ASN1_TYPE_set1(): set and ASN1_TYPE structure copying supplied | |
13 | data. | |
14 | [Steve Henson] | |
15 | ||
19398a17 BM |
16 | *) Fix BN flag handling in RSA_eay_mod_exp() and BN_MONT_CTX_set() |
17 | to get the expected BN_FLG_CONSTTIME behavior. | |
18 | [Bodo Moeller (Google)] | |
19 | ||
3b0e61a8 DSH |
20 | *) Netware support: |
21 | ||
22 | - fixed wrong usage of ioctlsocket() when build for LIBC BSD sockets | |
23 | - fixed do_tests.pl to run the test suite with CLIB builds too (CLIB_OPT) | |
24 | - added some more tests to do_tests.pl | |
25 | - fixed RunningProcess usage so that it works with newer LIBC NDKs too | |
26 | - removed usage of BN_LLONG for CLIB builds to avoid runtime dependency | |
27 | - added new Configure targets netware-clib-bsdsock, netware-clib-gcc, | |
28 | netware-clib-bsdsock-gcc, netware-libc-bsdsock-gcc | |
29 | - various changes to netware.pl to enable gcc-cross builds on Win32 | |
30 | platform | |
31 | - changed crypto/bio/b_sock.c to work with macro functions (CLIB BSD) | |
32 | - various changes to fix missing prototype warnings | |
33 | - fixed x86nasm.pl to create correct asm files for NASM COFF output | |
34 | - added AES, WHIRLPOOL and CPUID assembler code to build files | |
35 | - added missing AES assembler make rules to mk1mf.pl | |
36 | - fixed order of includes in apps/ocsp.c so that e_os.h settings apply | |
37 | [Guenter Knauf <eflash@gmx.net>] | |

a5232767 DSH |
39 | *) Implement certificate status request TLS extension defined in RFC3546. |
40 | A client can set the appropriate parameters and receive the encoded | |
41 | OCSP response via a callback. A server can query the supplied parameters | |
42 | and set the encoded OCSP response in the callback. Add simplified examples | |
43 | to s_client and s_server. | |
44 | [Steve Henson] | |

32f1f622 LJ |
46 | Changes between 0.9.8f and 0.9.8g [19 Oct 2007] |
47 | ||
48 | *) Fix various bugs: | |
49 | + Binary incompatibility of ssl_ctx_st structure | |
50 | + DTLS interoperation with non-compliant servers | |
51 | + Don't call get_session_cb() without proposed session | |
52 | + Fix ia64 assembler code | |
53 | [Andy Polyakov, Steve Henson] | |
54 | ||
dd002667 | 55 | Changes between 0.9.8e and 0.9.8f [11 Oct 2007] |
927a28ba | 56 | |
bb99ce5f BL |
57 | *) DTLS Handshake overhaul. There were longstanding issues with |
58 | OpenSSL DTLS implementation, which were making it impossible for | |
59 | RFC 4347 compliant client to communicate with OpenSSL server. | |
60 | Unfortunately just fixing these incompatibilities would "cut off" | |
61 | pre-0.9.8f clients. To allow for hassle free upgrade post-0.9.8e | |
62 | server keeps tolerating non RFC compliant syntax. The opposite is | |
63 | not true, 0.9.8f client can not communicate with earlier server. | |
64 | This update even addresses CVE-2007-4995. | |
65 | [Andy Polyakov] | |
66 | ||
927a28ba | 67 | *) Changes to avoid need for function casts in OpenSSL: some compilers |
294f03a8 DSH |
68 | (gcc 4.2 and later) reject their use. |
69 | [Kurt Roeckx <kurt@roeckx.be>, Peter Hartley <pdh@utter.chaos.org.uk>, | |
70 | Steve Henson] | |
865a90eb DSH |
71 | |
72 | *) Add RFC4507 support to OpenSSL. This includes the corrections in | |
73 | RFC4507bis. The encrypted ticket format is an encrypted encoded | |
74 | SSL_SESSION structure, that way new session features are automatically | |
75 | supported. | |
76 | ||
5b96d1cc DSH |
77 | If a client application caches session in an SSL_SESSION structure |
78 | support is transparent because tickets are now stored in the encoded | |
79 | SSL_SESSION. | |
80 | ||
81 | The SSL_CTX structure automatically generates keys for ticket | |
82 | protection in servers so again support should be possible | |
865a90eb DSH |
83 | with no application modification. |
84 | ||
85 | If a client or server wishes to disable RFC4507 support then the option | |
86 | SSL_OP_NO_TICKET can be set. | |
87 | ||
88 | Add a TLS extension debugging callback to allow the contents of any client | |
89 | or server extensions to be examined. | |
967ead72 DSH |
90 | |
91 | This work was sponsored by Google. | |
865a90eb DSH |
92 | [Steve Henson] |
93 | ||
94 | *) Add initial support for TLS extensions, specifically for the server_name | |
95 | extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now | |
96 | have new members for a host name. The SSL data structure has an | |
97 | additional member SSL_CTX *initial_ctx so that new sessions can be | |
98 | stored in that context to allow for session resumption, even after the | |
99 | SSL has been switched to a new SSL_CTX in reaction to a client's | |
100 | server_name extension. | |
101 | ||
102 | New functions (subject to change): | |
103 | ||
104 | SSL_get_servername() | |
105 | SSL_get_servername_type() | |
106 | SSL_set_SSL_CTX() | |
107 | ||
108 | New CTRL codes and macros (subject to change): | |
109 | ||
110 | SSL_CTRL_SET_TLSEXT_SERVERNAME_CB | |
111 | - SSL_CTX_set_tlsext_servername_callback() | |
112 | SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG | |
113 | - SSL_CTX_set_tlsext_servername_arg() | |
114 | SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name() | |
115 | ||
116 | openssl s_client has a new '-servername ...' option. | |
117 | ||
118 | openssl s_server has new options '-servername_host ...', '-cert2 ...', | |
119 | '-key2 ...', '-servername_fatal' (subject to change). This allows | |
120 | testing the HostName extension for a specific single host name ('-cert' | |
121 | and '-key' remain fallbacks for handshakes without HostName | |
122 | negotiation). If the unrecogninzed_name alert has to be sent, this by | |
123 | default is a warning; it becomes fatal with the '-servername_fatal' | |
124 | option. | |
125 | ||
126 | [Peter Sylvester, Remy Allais, Christophe Renou, Steve Henson] | |
5dd24ead | 127 | |
f805d307 DSH |
128 | *) Add AES and SSE2 assembly language support to VC++ build. |
129 | [Steve Henson] | |
130 | ||
4c5979a1 AP |
131 | *) Mitigate attack on final subtraction in Montgomery reduction. |
132 | [Andy Polyakov] | |
133 | ||
b22250bb BM |
134 | *) Fix crypto/ec/ec_mult.c to work properly with scalars of value 0 |
135 | (which previously caused an internal error). | |
136 | [Bodo Moeller] | |
137 | ||
8957121c BL |
138 | *) Squeeze another 10% out of IGE mode when in != out. |
139 | [Ben Laurie] | |
140 | ||
50241bc8 BL |
141 | *) AES IGE mode speedup. |
142 | [Dean Gaudet (Google)] | |
143 | ||
c3cc4662 BM |
144 | *) Add the Korean symmetric 128-bit cipher SEED (see |
145 | http://www.kisa.or.kr/kisa/seed/jsp/seed_eng.jsp) and | |
146 | add SEED ciphersuites from RFC 4162: | |
147 | ||
148 | TLS_RSA_WITH_SEED_CBC_SHA = "SEED-SHA" | |
149 | TLS_DHE_DSS_WITH_SEED_CBC_SHA = "DHE-DSS-SEED-SHA" | |
150 | TLS_DHE_RSA_WITH_SEED_CBC_SHA = "DHE-RSA-SEED-SHA" | |
151 | TLS_DH_anon_WITH_SEED_CBC_SHA = "ADH-SEED-SHA" | |
152 | ||
153 | To minimize changes between patchlevels in the OpenSSL 0.9.8 | |
154 | series, SEED remains excluded from compilation unless OpenSSL | |
155 | is configured with 'enable-seed'. | |
156 | [KISA, Bodo Moeller] | |
157 | ||
7cdb8158 BM |
158 | *) Mitigate branch prediction attacks, which can be practical if a |
159 | single processor is shared, allowing a spy process to extract | |
160 | information. For detailed background information, see | |
161 | http://eprint.iacr.org/2007/039 (O. Aciicmez, S. Gueron, | |
162 | J.-P. Seifert, "New Branch Prediction Vulnerabilities in OpenSSL | |
163 | and Necessary Software Countermeasures"). The core of the change | |
164 | are new versions BN_div_no_branch() and | |
165 | BN_mod_inverse_no_branch() of BN_div() and BN_mod_inverse(), | |
166 | respectively, which are slower, but avoid the security-relevant | |
167 | conditional branches. These are automatically called by BN_div() | |
2ac061e4 BM |
168 | and BN_mod_inverse() if the flag BN_FLG_CONSTTIME is set for one |
169 | of the input BIGNUMs. Also, BN_is_bit_set() has been changed to | |
170 | remove a conditional branch. | |
7cdb8158 BM |
171 | |
172 | BN_FLG_CONSTTIME is the new name for the previous | |
173 | BN_FLG_EXP_CONSTTIME flag, since it now affects more than just | |
174 | modular exponentiation. (Since OpenSSL 0.9.7h, setting this flag | |
175 | in the exponent causes BN_mod_exp_mont() to use the alternative | |
176 | implementation in BN_mod_exp_mont_consttime().) The old name | |
177 | remains as a deprecated alias. | |
178 | ||
179 | Similary, RSA_FLAG_NO_EXP_CONSTTIME is replaced by a more general | |
180 | RSA_FLAG_NO_CONSTTIME flag since the RSA implementation now uses | |
181 | constant-time implementations for more than just exponentiation. | |
182 | Here too the old name is kept as a deprecated alias. | |
183 | ||
184 | BN_BLINDING_new() will now use BN_dup() for the modulus so that | |
185 | the BN_BLINDING structure gets an independent copy of the | |
186 | modulus. This means that the previous "BIGNUM *m" argument to | |
187 | BN_BLINDING_new() and to BN_BLINDING_create_param() now | |
188 | essentially becomes "const BIGNUM *m", although we can't actually | |
189 | change this in the header file before 0.9.9. It allows | |
190 | RSA_setup_blinding() to use BN_with_flags() on the modulus to | |
191 | enable BN_FLG_CONSTTIME. | |
192 | ||
193 | [Matthew D Wood (Intel Corp)] | |
194 | ||
6fd3f326 BM |
195 | *) In the SSL/TLS server implementation, be strict about session ID |
196 | context matching (which matters if an application uses a single | |
197 | external cache for different purposes). Previously, | |
198 | out-of-context reuse was forbidden only if SSL_VERIFY_PEER was | |
199 | set. This did ensure strict client verification, but meant that, | |
200 | with applications using a single external cache for quite | |
201 | different requirements, clients could circumvent ciphersuite | |
202 | restrictions for a given session ID context by starting a session | |
203 | in a different context. | |
204 | [Bodo Moeller] | |
205 | ||
55f05012 BM |
206 | *) Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that |
207 | a ciphersuite string such as "DEFAULT:RSA" cannot enable | |
208 | authentication-only ciphersuites. | |
209 | [Bodo Moeller] | |
210 | ||
216ac24b MC |
211 | *) Update the SSL_get_shared_ciphers() fix CVE-2006-3738 which was |
212 | not complete and could lead to a possible single byte overflow | |
213 | (CVE-2007-5135) [Ben Laurie] | |
214 | ||
d9e26244 BM |
215 | Changes between 0.9.8d and 0.9.8e [23 Feb 2007] |
216 | ||
5f4cc234 BM |
217 | *) Since AES128 and AES256 (and similarly Camellia128 and |
218 | Camellia256) share a single mask bit in the logic of | |
219 | ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a | |
220 | kludge to work properly if AES128 is available and AES256 isn't | |
221 | (or if Camellia128 is available and Camellia256 isn't). | |
222 | [Victor Duchovni] | |
223 | ||
1a8521ff BM |
224 | *) Fix the BIT STRING encoding generated by crypto/ec/ec_asn1.c |
225 | (within i2d_ECPrivateKey, i2d_ECPKParameters, i2d_ECParameters): | |
226 | When a point or a seed is encoded in a BIT STRING, we need to | |
227 | prevent the removal of trailing zero bits to get the proper DER | |
228 | encoding. (By default, crypto/asn1/a_bitstr.c assumes the case | |
229 | of a NamedBitList, for which trailing 0 bits need to be removed.) | |
230 | [Bodo Moeller] | |
231 | ||
5c6f76da BM |
232 | *) Have SSL/TLS server implementation tolerate "mismatched" record |
233 | protocol version while receiving ClientHello even if the | |
234 | ClientHello is fragmented. (The server can't insist on the | |
235 | particular protocol version it has chosen before the ServerHello | |
236 | message has informed the client about his choice.) | |
237 | [Bodo Moeller] | |
238 | ||
4636341b BL |
239 | *) Add RFC 3779 support. |
240 | [Rob Austein for ARIN, Ben Laurie] | |
25e52a78 | 241 | |
900f7a87 DSH |
242 | *) Load error codes if they are not already present instead of using a |
243 | static variable. This allows them to be cleanly unloaded and reloaded. | |
244 | Improve header file function name parsing. | |
245 | [Steve Henson] | |
246 | ||
cdb13ae8 LJ |
247 | *) extend SMTP and IMAP protocol emulation in s_client to use EHLO |
248 | or CAPABILITY handshake as required by RFCs. | |
249 | [Goetz Babin-Ebell] | |
250 | ||
47c4bb2d | 251 | Changes between 0.9.8c and 0.9.8d [28 Sep 2006] |
da1841a0 | 252 | |
951dfbb1 MC |
253 | *) Introduce limits to prevent malicious keys being able to |
254 | cause a denial of service. (CVE-2006-2940) | |
255 | [Steve Henson, Bodo Moeller] | |
256 | ||
257 | *) Fix ASN.1 parsing of certain invalid structures that can result | |
258 | in a denial of service. (CVE-2006-2937) [Steve Henson] | |
259 | ||
260 | *) Fix buffer overflow in SSL_get_shared_ciphers() function. | |
261 | (CVE-2006-3738) [Tavis Ormandy and Will Drewry, Google Security Team] | |
262 | ||
263 | *) Fix SSL client code which could crash if connecting to a | |
264 | malicious SSLv2 server. (CVE-2006-4343) | |
265 | [Tavis Ormandy and Will Drewry, Google Security Team] | |
266 | ||
879b30aa BM |
267 | *) Since 0.9.8b, ciphersuite strings naming explicit ciphersuites |
268 | match only those. Before that, "AES256-SHA" would be interpreted | |
8fdb296c BM |
269 | as a pattern and match "AES128-SHA" too (since AES128-SHA got |
270 | the same strength classification in 0.9.7h) as we currently only | |
879b30aa BM |
271 | have a single AES bit in the ciphersuite description bitmap. |
272 | That change, however, also applied to ciphersuite strings such as | |
273 | "RC4-MD5" that intentionally matched multiple ciphersuites -- | |
274 | namely, SSL 2.0 ciphersuites in addition to the more common ones | |
275 | from SSL 3.0/TLS 1.0. | |
276 | ||
277 | So we change the selection algorithm again: Naming an explicit | |
278 | ciphersuite selects this one ciphersuite, and any other similar | |
279 | ciphersuite (same bitmap) from *other* protocol versions. | |
280 | Thus, "RC4-MD5" again will properly select both the SSL 2.0 | |
281 | ciphersuite and the SSL 3.0/TLS 1.0 ciphersuite. | |
282 | ||
283 | Since SSL 2.0 does not have any ciphersuites for which the | |
284 | 128/256 bit distinction would be relevant, this works for now. | |
285 | The proper fix will be to use different bits for AES128 and | |
286 | AES256, which would have avoided the problems from the beginning; | |
287 | however, bits are scarce, so we can only do this in a new release | |
288 | (not just a patchlevel) when we can change the SSL_CIPHER | |
289 | definition to split the single 'unsigned long mask' bitmap into | |
290 | multiple values to extend the available space. | |
291 | ||
292 | [Bodo Moeller] | |
293 | ||
0a0a10d1 | 294 | Changes between 0.9.8b and 0.9.8c [05 Sep 2006] |
1c5dc844 | 295 | |
df20b6e7 MC |
296 | *) Avoid PKCS #1 v1.5 signature attack discovered by Daniel Bleichenbacher |
297 | (CVE-2006-4339) [Ben Laurie and Google Security Team] | |
298 | ||
4b9dcd82 BL |
299 | *) Add AES IGE and biIGE modes. |
300 | [Ben Laurie] | |
301 | ||
ec67e3b7 BM |
302 | *) Change the Unix randomness entropy gathering to use poll() when |
303 | possible instead of select(), since the latter has some | |
304 | undesirable limitations. | |
305 | [Darryl Miles via Richard Levitte and Bodo Moeller] | |
306 | ||
aa17ab7e BM |
307 | *) Disable "ECCdraft" ciphersuites more thoroughly. Now special |
308 | treatment in ssl/ssl_ciph.s makes sure that these ciphersuites | |
309 | cannot be implicitly activated as part of, e.g., the "AES" alias. | |
310 | However, please upgrade to OpenSSL 0.9.9[-dev] for | |
311 | non-experimental use of the ECC ciphersuites to get TLS extension | |
312 | support, which is required for curve and point format negotiation | |
313 | to avoid potential handshake problems. | |
35908bd0 BM |
314 | [Bodo Moeller] |
315 | ||
0e73294e BM |
316 | *) Disable rogue ciphersuites: |
317 | ||
318 | - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5") | |
319 | - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5") | |
320 | - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5") | |
321 | ||
322 | The latter two were purportedly from | |
323 | draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really | |
324 | appear there. | |
325 | ||
68bb9815 | 326 | Also deactivate the remaining ciphersuites from |
0e73294e BM |
327 | draft-ietf-tls-56-bit-ciphersuites-01.txt. These are just as |
328 | unofficial, and the ID has long expired. | |
329 | [Bodo Moeller] | |
330 | ||
6d2cd23f BM |
331 | *) Fix RSA blinding Heisenbug (problems sometimes occured on |
332 | dual-core machines) and other potential thread-safety issues. | |
333 | [Bodo Moeller] | |
334 | ||
e18eef3d BM |
335 | *) Add the symmetric cipher Camellia (128-bit, 192-bit, 256-bit key |
336 | versions), which is now available for royalty-free use | |
337 | (see http://info.isl.ntt.co.jp/crypt/eng/info/chiteki.html). | |
338 | Also, add Camellia TLS ciphersuites from RFC 4132. | |
339 | ||
340 | To minimize changes between patchlevels in the OpenSSL 0.9.8 | |
341 | series, Camellia remains excluded from compilation unless OpenSSL | |
342 | is configured with 'enable-camellia'. | |
343 | [NTT] | |
344 | ||
b723a7b1 DSH |
345 | *) Disable the padding bug check when compression is in use. The padding |
346 | bug check assumes the first packet is of even length, this is not | |
347 | necessarily true if compresssion is enabled and can result in false | |
348 | positives causing handshake failure. The actual bug test is ancient | |
349 | code so it is hoped that implementations will either have fixed it by | |
350 | now or any which still have the bug do not support compression. | |
351 | [Steve Henson] | |
1c5dc844 | 352 | |
f871949e | 353 | Changes between 0.9.8a and 0.9.8b [04 May 2006] |
d8b408b1 | 354 | |
cbb0b734 DSH |
355 | *) When applying a cipher rule check to see if string match is an explicit |
356 | cipher suite and only match that one cipher suite if it is. | |
357 | [Steve Henson] | |
358 | ||
217382d5 DSH |
359 | *) Link in manifests for VC++ if needed. |
360 | [Austin Ziegler <halostatue@gmail.com>] | |
361 | ||
bc932045 | 362 | *) Update support for ECC-based TLS ciphersuites according to |
5586a71a BM |
363 | draft-ietf-tls-ecc-12.txt with proposed changes (but without |
364 | TLS extensions, which are supported starting with the 0.9.9 | |
365 | branch, not in the OpenSSL 0.9.8 branch). | |
bc932045 BM |
366 | [Douglas Stebila] |
367 | ||
23d43aae BM |
368 | *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support |
369 | opaque EVP_CIPHER_CTX handling. | |
370 | [Steve Henson] | |
371 | ||
7614f0e5 DSH |
372 | *) Fixes and enhancements to zlib compression code. We now only use |
373 | "zlib1.dll" and use the default __cdecl calling convention on Win32 | |
374 | to conform with the standards mentioned here: | |
375 | http://www.zlib.net/DLL_FAQ.txt | |
376 | Static zlib linking now works on Windows and the new --with-zlib-include | |
377 | --with-zlib-lib options to Configure can be used to supply the location | |
378 | of the headers and library. Gracefully handle case where zlib library | |
379 | can't be loaded. | |
380 | [Steve Henson] | |
381 | ||
feef17fd DSH |
382 | *) Several fixes and enhancements to the OID generation code. The old code |
383 | sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't | |
384 | handle numbers larger than ULONG_MAX, truncated printing and had a | |
385 | non standard OBJ_obj2txt() behaviour. | |
386 | [Steve Henson] | |
387 | ||
abb0c2bb DSH |
388 | *) Add support for building of engines under engine/ as shared libraries |
389 | under VC++ build system. | |
390 | [Steve Henson] | |
391 | ||
d3afc92b RL |
392 | *) Corrected the numerous bugs in the Win32 path splitter in DSO. |
393 | Hopefully, we will not see any false combination of paths any more. | |
394 | [Richard Levitte] | |
395 | ||
64932f9e MC |
396 | Changes between 0.9.8 and 0.9.8a [11 Oct 2005] |
397 | ||
398 | *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING | |
399 | (part of SSL_OP_ALL). This option used to disable the | |
400 | countermeasure against man-in-the-middle protocol-version | |
401 | rollback in the SSL 2.0 server implementation, which is a bad | |
802c0146 | 402 | idea. (CVE-2005-2969) |
64932f9e MC |
403 | |
404 | [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center | |
405 | for Information Security, National Institute of Advanced Industrial | |
406 | Science and Technology [AIST], Japan)] | |
750cb3d2 | 407 | |
0fce007b DSH |
408 | *) Add two function to clear and return the verify parameter flags. |
409 | [Steve Henson] | |
410 | ||
3c0e39c5 NL |
411 | *) Keep cipherlists sorted in the source instead of sorting them at |
412 | runtime, thus removing the need for a lock. | |
413 | [Nils Larsch] | |
414 | ||
19fddebf | 415 | *) Avoid some small subgroup attacks in Diffie-Hellman. |
60864221 BL |
416 | [Nick Mathewson and Ben Laurie] |
417 | ||
418 | *) Add functions for well-known primes. | |
419 | [Nick Mathewson] | |
9ddb11f1 | 420 | |
98e98614 AP |
421 | *) Extended Windows CE support. |
422 | [Satoshi Nakamura and Andy Polyakov] | |
423 | ||
222f2246 DSH |
424 | *) Initialize SSL_METHOD structures at compile time instead of during |
425 | runtime, thus removing the need for a lock. | |
426 | [Steve Henson] | |
427 | ||
1682e8fb DSH |
428 | *) Make PKCS7_decrypt() work even if no certificate is supplied by |
429 | attempting to decrypt each encrypted key in turn. Add support to | |
430 | smime utility. | |
431 | [Steve Henson] | |
750cb3d2 | 432 | |
f254b540 | 433 | Changes between 0.9.7h and 0.9.8 [05 Jul 2005] |
12bdb643 | 434 | |
6d2cd23f BM |
435 | [NB: OpenSSL 0.9.7i and later 0.9.7 patch levels were released after |
436 | OpenSSL 0.9.8.] | |
437 | ||
1d01c9d4 RL |
438 | *) Add libcrypto.pc and libssl.pc for those who feel they need them. |
439 | [Richard Levitte] | |
440 | ||
441 | *) Change CA.sh and CA.pl so they don't bundle the CSR and the private | |
442 | key into the same file any more. | |
443 | [Richard Levitte] | |
444 | ||
e32ea818 AP |
445 | *) Add initial support for Win64, both IA64 and AMD64/x64 flavors. |
446 | [Andy Polyakov] | |
447 | ||
09c1a425 DSH |
448 | *) Add -utf8 command line and config file option to 'ca'. |
449 | [Stefan <stf@udoma.org] | |
450 | ||
1d01c9d4 RL |
451 | *) Removed the macro des_crypt(), as it seems to conflict with some |
452 | libraries. Use DES_crypt(). | |
453 | [Richard Levitte] | |
454 | ||
a4578a54 GT |
455 | *) Correct naming of the 'chil' and '4758cca' ENGINEs. This |
456 | involves renaming the source and generated shared-libs for | |
457 | both. The engines will accept the corrected or legacy ids | |
458 | ('ncipher' and '4758_cca' respectively) when binding. NB, | |
459 | this only applies when building 'shared'. | |
460 | [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe] | |
461 | ||
b6995add DSH |
462 | *) Add attribute functions to EVP_PKEY structure. Modify |
463 | PKCS12_create() to recognize a CSP name attribute and | |
464 | use it. Make -CSP option work again in pkcs12 utility. | |
465 | [Steve Henson] | |
466 | ||
800e400d NL |
467 | *) Add new functionality to the bn blinding code: |
468 | - automatic re-creation of the BN_BLINDING parameters after | |
469 | a fixed number of uses (currently 32) | |
470 | - add new function for parameter creation | |
471 | - introduce flags to control the update behaviour of the | |
472 | BN_BLINDING parameters | |
473 | - hide BN_BLINDING structure | |
474 | Add a second BN_BLINDING slot to the RSA structure to improve | |
475 | performance when a single RSA object is shared among several | |
476 | threads. | |
477 | [Nils Larsch] | |
478 | ||
36d16f8e BL |
479 | *) Add support for DTLS. |
480 | [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie] | |
481 | ||
dc0ed30c NL |
482 | *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1) |
483 | to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file() | |
484 | [Walter Goulet] | |
485 | ||
6049399b NL |
486 | *) Remove buggy and incompletet DH cert support from |
487 | ssl/ssl_rsa.c and ssl/s3_both.c | |
488 | [Nils Larsch] | |
489 | ||
12bdb643 NL |
490 | *) Use SHA-1 instead of MD5 as the default digest algorithm for |
491 | the apps/openssl applications. | |
492 | [Nils Larsch] | |
4d94ae00 | 493 | |
41a15c4f BL |
494 | *) Compile clean with "-Wall -Wmissing-prototypes |
495 | -Wstrict-prototypes -Wmissing-declarations -Werror". Currently | |
496 | DEBUG_SAFESTACK must also be set. | |
497 | [Ben Laurie] | |
498 | ||
c9a112f5 | 499 | *) Change ./Configure so that certain algorithms can be disabled by default. |
ecc5ef87 BM |
500 | The new counterpiece to "no-xxx" is "enable-xxx". |
501 | ||
502 | The patented RC5 and MDC2 algorithms will now be disabled unless | |
503 | "enable-rc5" and "enable-mdc2", respectively, are specified. | |
504 | ||
505 | (IDEA remains enabled despite being patented. This is because IDEA | |
506 | is frequently required for interoperability, and there is no license | |
507 | fee for non-commercial use. As before, "no-idea" can be used to | |
508 | avoid this algorithm.) | |
509 | ||
c9a112f5 BM |
510 | [Bodo Moeller] |
511 | ||
6951c23a RL |
512 | *) Add processing of proxy certificates (see RFC 3820). This work was |
513 | sponsored by KTH (The Royal Institute of Technology in Stockholm) and | |
514 | EGEE (Enabling Grids for E-science in Europe). | |
515 | [Richard Levitte] | |
516 | ||
ea681ba8 AP |
517 | *) RC4 performance overhaul on modern architectures/implementations, such |
518 | as Intel P4, IA-64 and AMD64. | |
519 | [Andy Polyakov] | |
520 | ||
401ee37a DSH |
521 | *) New utility extract-section.pl. This can be used specify an alternative |
522 | section number in a pod file instead of having to treat each file as | |
523 | a separate case in Makefile. This can be done by adding two lines to the | |
524 | pod file: | |
525 | ||
526 | =for comment openssl_section:XXX | |
527 | ||
528 | The blank line is mandatory. | |
529 | ||
530 | [Steve Henson] | |
531 | ||
826a42a0 DSH |
532 | *) New arguments -certform, -keyform and -pass for s_client and s_server |
533 | to allow alternative format key and certificate files and passphrase | |
534 | sources. | |
535 | [Steve Henson] | |
536 | ||
5d7c222d DSH |
537 | *) New structure X509_VERIFY_PARAM which combines current verify parameters, |
538 | update associated structures and add various utility functions. | |
539 | ||
540 | Add new policy related verify parameters, include policy checking in | |
541 | standard verify code. Enhance 'smime' application with extra parameters | |
542 | to support policy checking and print out. | |
543 | [Steve Henson] | |
544 | ||
30fe028f GT |
545 | *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3 |
546 | Nehemiah processors. These extensions support AES encryption in hardware | |
547 | as well as RNG (though RNG support is currently disabled). | |
548 | [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov] | |
549 | ||
df11e1e9 GT |
550 | *) Deprecate BN_[get|set]_params() functions (they were ignored internally). |
551 | [Geoff Thorpe] | |
552 | ||
ad500340 AP |
553 | *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented. |
554 | [Andy Polyakov and a number of other people] | |
555 | ||
e14f4aab AP |
556 | *) Improved PowerPC platform support. Most notably BIGNUM assembler |
557 | implementation contributed by IBM. | |
558 | [Suresh Chari, Peter Waltenberg, Andy Polyakov] | |
559 | ||
bcfea9fb GT |
560 | *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public |
561 | exponent rather than 'unsigned long'. There is a corresponding change to | |
562 | the new 'rsa_keygen' element of the RSA_METHOD structure. | |
563 | [Jelte Jansen, Geoff Thorpe] | |
564 | ||
d5f686d8 BM |
565 | *) Functionality for creating the initial serial number file is now |
566 | moved from CA.pl to the 'ca' utility with a new option -create_serial. | |
567 | ||
568 | (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial | |
569 | number file to 1, which is bound to cause problems. To avoid | |
570 | the problems while respecting compatibility between different 0.9.7 | |
571 | patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in | |
572 | CA.pl for serial number initialization. With the new release 0.9.8, | |
573 | we can fix the problem directly in the 'ca' utility.) | |
64674bcc DSH |
574 | [Steve Henson] |
575 | ||
3a87a9b9 GT |
576 | *) Reduced header interdepencies by declaring more opaque objects in |
577 | ossl_typ.h. As a consequence, including some headers (eg. engine.h) will | |
578 | give fewer recursive includes, which could break lazy source code - so | |
579 | this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always, | |
580 | developers should define this symbol when building and using openssl to | |
581 | ensure they track the recommended behaviour, interfaces, [etc], but | |
582 | backwards-compatible behaviour prevails when this isn't defined. | |
583 | [Geoff Thorpe] | |
584 | ||
bf5773fa DSH |
585 | *) New function X509_POLICY_NODE_print() which prints out policy nodes. |
586 | [Steve Henson] | |
587 | ||
216659eb DSH |
588 | *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality. |
589 | This will generate a random key of the appropriate length based on the | |
590 | cipher context. The EVP_CIPHER can provide its own random key generation | |
591 | routine to support keys of a specific form. This is used in the des and | |
592 | 3des routines to generate a key of the correct parity. Update S/MIME | |
593 | code to use new functions and hence generate correct parity DES keys. | |
594 | Add EVP_CHECK_DES_KEY #define to return an error if the key is not | |
595 | valid (weak or incorrect parity). | |
596 | [Steve Henson] | |
597 | ||
e1a27eb3 DSH |
598 | *) Add a local set of CRLs that can be used by X509_verify_cert() as well |
599 | as looking them up. This is useful when the verified structure may contain | |
600 | CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs | |
601 | present unless the new PKCS7_NO_CRL flag is asserted. | |
602 | [Steve Henson] | |
603 | ||
6446e0c3 DSH |
604 | *) Extend ASN1 oid configuration module. It now additionally accepts the |
605 | syntax: | |
606 | ||
607 | shortName = some long name, 1.2.3.4 | |
608 | [Steve Henson] | |
609 | ||
5c98b2ca GT |
610 | *) Reimplemented the BN_CTX implementation. There is now no more static |
611 | limitation on the number of variables it can handle nor the depth of the | |
612 | "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack | |
613 | information can now expand as required, and rather than having a single | |
614 | static array of bignums, BN_CTX now uses a linked-list of such arrays | |
615 | allowing it to expand on demand whilst maintaining the usefulness of | |
616 | BN_CTX's "bundling". | |
617 | [Geoff Thorpe] | |
618 | ||
46ef873f GT |
619 | *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD |
620 | to allow all RSA operations to function using a single BN_CTX. | |
621 | [Geoff Thorpe] | |
622 | ||
4acc3e90 DSH |
623 | *) Preliminary support for certificate policy evaluation and checking. This |
624 | is initially intended to pass the tests outlined in "Conformance Testing | |
625 | of Relying Party Client Certificate Path Processing Logic" v1.07. | |
626 | [Steve Henson] | |
627 | ||
7f663ce4 GT |
628 | *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and |
629 | remained unused and not that useful. A variety of other little bignum | |
630 | tweaks and fixes have also been made continuing on from the audit (see | |
631 | below). | |
632 | [Geoff Thorpe] | |
633 | ||
875a644a RL |
634 | *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with |
635 | associated ASN1, EVP and SSL functions and old ASN1 macros. | |
7f663ce4 | 636 | [Richard Levitte] |
875a644a | 637 | |
b6358c89 GT |
638 | *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results, |
639 | and this should never fail. So the return value from the use of | |
640 | BN_set_word() (which can fail due to needless expansion) is now deprecated; | |
641 | if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro. | |
642 | [Geoff Thorpe] | |
643 | ||
9e051bac GT |
644 | *) BN_CTX_get() should return zero-valued bignums, providing the same |
645 | initialised value as BN_new(). | |
646 |
