bf3d6c0c | 5 | Changes between 0.9.8a and 0.9.9 [xx XXX xxxx] |
28e4fe34 | 6 | |
f1fd4544 BM |
7 | *) Add support for TLS extensions, specifically for the HostName extension |
8 | so far. The SSL_SESSION, SSL_CTX, and SSL data structures now have new | |
9 | members for HostName support. | |
10 | ||
11 | New functions (subject to change): | |
12 | ||
13 | SSL_get_servername() | |
14 | SSL_get_servername_type() | |
15 | SSL_set_SSL_CTX() | |
16 | ||
17 | New CTRL codes and macros (subject to change): | |
18 | ||
19 | SSL_CTRL_SET_TLSEXT_SERVERNAME_CB | |
20 | - SSL_CTX_set_tlsext_servername_callback() | |
21 | SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG | |
22 | - SSL_CTX_set_tlsext_servername_arg() | |
23 | SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_hostname() | |
24 | SSL_CTRL_GET_TLSEXT_HOSTNAME [similar to SSL_get_servername()] | |
25 | SSL_CTRL_SET_TLSEXT_SERVERNAME_DONE | |
26 | - SSL_set_tlsext_servername_done() | |
b1277b99 BM |
27 | |
28 | openssl s_client has a new '-servername' option. | |
29 | ||
f1fd4544 BM |
30 | openssl s_server has new options '-servername', '-cert2', and '-key2' |
31 | (subject to change); this allows testing the HostName extension for a | |
32 | specific single host name ('-cert' and '-key' remain fallbacks for | |
33 | handshakes without HostName negotiation). | |
b1277b99 BM |
34 | |
35 | [Peter Sylvester] | |
36 | ||
ed26604a AP |
37 | *) Whirlpool hash implementation is added. |
38 | [Andy Polyakov] | |
39 | ||
0cb9d93d AP |
40 | *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to |
41 | bn(64,32). Because of instruction set limitations it doesn't have | |
42 | any negative impact on performance. This was done mostly in order | |
43 | to make it possible to share assembler modules, such as bn_mul_mont | |
44 | implementations, between 32- and 64-bit builds without hassle. | |
45 | [Andy Polyakov] | |
46 | ||
d804f86b BM |
47 | *) Disable rogue ciphersuites: |
48 | ||
49 | - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5") | |
50 | - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5") | |
51 | - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5") | |
52 | ||
53 | The latter two were purportedly from | |
54 | draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really | |
55 | appear there. | |
56 | ||
57 | Other ciphersuites from draft-ietf-tls-56-bit-ciphersuites-01.txt | |
58 | remain enabled for now, but are just as unofficial, and the ID | |
59 | has long expired; these will probably disappear soon. | |
60 | [Bodo Moeller] | |
61 | ||
8dee9f84 BM |
62 | *) Move code previously exiled into file crypto/ec/ec2_smpt.c |
63 | to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP | |
64 | macro. | |
65 | [Bodo Moeller] | |
66 | ||
4d524040 AP |
67 | *) New candidate for BIGNUM assembler implementation, bn_mul_mont, |
68 | dedicated Montgomery multiplication procedure, is introduced. | |
69 | BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher | |
70 | "64-bit" performance on certain 32-bit targets. | |
71 | [Andy Polyakov] | |
72 | ||
566dda07 DSH |
73 | *) New option SSL_OP_NO_COMP to disable use of compression selectively |
74 | in SSL structures. New SSL ctrl to set maximum send fragment size. | |
75 | Save memory by seeting the I/O buffer sizes dynamically instead of | |
76 | using the maximum available value. | |
77 | [Steve Henson] | |
78 | ||
13e4670c BM |
79 | *) New option -V for 'openssl ciphers'. This prints the ciphersuite code |
80 | in addition to the text details. | |
81 | [Bodo Moeller] | |
82 | ||
1ef7acfe DSH |
83 | *) Very, very preliminary EXPERIMENTAL support for printing of general |
84 | ASN1 structures. This currently produces rather ugly output and doesn't | |
85 | handle several customised structures at all. | |
86 | [Steve Henson] | |
87 | ||
a0156a92 DSH |
88 | *) Integrated support for PVK file format and some related formats such |
89 | as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support | |
90 | these in the 'rsa' and 'dsa' utilities. | |
91 | [Steve Henson] | |
92 | ||
eea374fd DSH |
93 | *) Support for PKCS#1 RSAPublicKey format on rsa utility command line. |
94 | [Steve Henson] | |
95 | ||
45e27385 DSH |
96 | *) Remove the ancient ASN1_METHOD code. This was only ever used in one |
97 | place for the (very old) "NETSCAPE" format certificates which are now | |
98 | handled using new ASN1 code equivalents. | |
eea374fd | 99 | [Steve Henson] |
45e27385 | 100 | |
4ebb342f NL |
101 | *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD |
102 | pointer and make the SSL_METHOD parameter in SSL_CTX_new, | |
103 | SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'. | |
104 | [Nils Larsch] | |
105 | ||
9aa9d70d | 106 | *) Modify CRL distribution points extension code to print out previously |
0745d089 DSH |
107 | unsupported fields. Enhance extension setting code to allow setting of |
108 | all fields. | |
9aa9d70d DSH |
109 | [Steve Henson] |
110 | ||
0537f968 | 111 | *) Add print and set support for Issuing Distribution Point CRL extension. |
231493c9 | 112 | [Steve Henson] |
28e4fe34 | 113 | |
998ac55e RL |
114 | Changes between 0.9.8a and 0.9.8b [XX xxx XXXX] |
115 | ||
d56349a2 BM |
116 | *) Update support for ECC-based TLS ciphersuites according to |
117 | draft-ietf-tls-ecc-12.txt with proposed changes. | |
118 | [Douglas Stebila] | |
119 | ||
b40228a6 DSH |
120 | *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support |
121 | opaque EVP_CIPHER_CTX handling. | |
122 | [Steve Henson] | |
123 | ||
ad2695b1 DSH |
124 | *) Fixes and enhancements to zlib compression code. We now only use |
125 | "zlib1.dll" and use the default __cdecl calling convention on Win32 | |
126 | to conform with the standards mentioned here: | |
127 | http://www.zlib.net/DLL_FAQ.txt | |
128 | Static zlib linking now works on Windows and the new --with-zlib-include | |
129 | --with-zlib-lib options to Configure can be used to supply the location | |
130 | of the headers and library. Gracefully handle case where zlib library | |
131 | can't be loaded. | |
132 | [Steve Henson] | |
133 | ||
452ae49d DSH |
134 | *) Several fixes and enhancements to the OID generation code. The old code |
135 | sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't | |
136 | handle numbers larger than ULONG_MAX, truncated printing and had a | |
137 | non standard OBJ_obj2txt() behaviour. | |
138 | [Steve Henson] | |
139 | ||
fbf002bb DSH |
140 | *) Add support for building of engines under engine/ as shared libraries |
141 | under VC++ build system. | |
142 | [Steve Henson] | |
143 | ||
998ac55e RL |
144 | *) Corrected the numerous bugs in the Win32 path splitter in DSO. |
145 | Hopefully, we will not see any false combination of paths any more. | |
146 | [Richard Levitte] | |
147 | ||
d357be38 MC |
148 | Changes between 0.9.8 and 0.9.8a [11 Oct 2005] |
149 | ||
150 | *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING | |
151 | (part of SSL_OP_ALL). This option used to disable the | |
152 | countermeasure against man-in-the-middle protocol-version | |
153 | rollback in the SSL 2.0 server implementation, which is a bad | |
04fac373 | 154 | idea. (CVE-2005-2969) |
d357be38 MC |
155 | |
156 | [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center | |
157 | for Information Security, National Institute of Advanced Industrial | |
158 | Science and Technology [AIST], Japan)] | |
2bd2cd9b | 159 | |
f022c177 DSH |
160 | *) Add two function to clear and return the verify parameter flags. |
161 | [Steve Henson] | |
162 | ||
6e119bb0 NL |
163 | *) Keep cipherlists sorted in the source instead of sorting them at |
164 | runtime, thus removing the need for a lock. | |
165 | [Nils Larsch] | |
166 | ||
770bc596 | 167 | *) Avoid some small subgroup attacks in Diffie-Hellman. |
bf3d6c0c BL |
168 | [Nick Mathewson and Ben Laurie] |
169 | ||
170 | *) Add functions for well-known primes. | |
171 | [Nick Mathewson] | |
172 | ||
0491e058 AP |
173 | *) Extended Windows CE support. |
174 | [Satoshi Nakamura and Andy Polyakov] | |
a1006c37 | 175 | |
f3b656b2 DSH |
176 | *) Initialize SSL_METHOD structures at compile time instead of during |
177 | runtime, thus removing the need for a lock. | |
178 | [Steve Henson] | |
179 | ||
8f2e4fdf DSH |
180 | *) Make PKCS7_decrypt() work even if no certificate is supplied by |
181 | attempting to decrypt each encrypted key in turn. Add support to | |
182 | smime utility. | |
183 | [Steve Henson] | |
2bd2cd9b RL |
184 | |
185 | Changes between 0.9.7h and 0.9.8 [05 Jul 2005] | |
12bdb643 | 186 | |
c8310124 RL |
187 | *) Add libcrypto.pc and libssl.pc for those who feel they need them. |
188 | [Richard Levitte] | |
189 | ||
190 | *) Change CA.sh and CA.pl so they don't bundle the CSR and the private | |
191 | key into the same file any more. | |
192 | [Richard Levitte] | |
193 | ||
8d3509b9 AP |
194 | *) Add initial support for Win64, both IA64 and AMD64/x64 flavors. |
195 | [Andy Polyakov] | |
196 | ||
cbdac46d DSH |
197 | *) Add -utf8 command line and config file option to 'ca'. |
198 | [Stefan <stf@udoma.org] | |
199 | ||
c8310124 RL |
200 | *) Removed the macro des_crypt(), as it seems to conflict with some |
201 | libraries. Use DES_crypt(). | |
202 | [Richard Levitte] | |
203 | ||
a2c32e2d GT |
204 | *) Correct naming of the 'chil' and '4758cca' ENGINEs. This |
205 | involves renaming the source and generated shared-libs for | |
206 | both. The engines will accept the corrected or legacy ids | |
207 | ('ncipher' and '4758_cca' respectively) when binding. NB, | |
208 | this only applies when building 'shared'. | |
209 | [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe] | |
210 | ||
b6995add DSH |
211 | *) Add attribute functions to EVP_PKEY structure. Modify |
212 | PKCS12_create() to recognize a CSP name attribute and | |
213 | use it. Make -CSP option work again in pkcs12 utility. | |
214 | [Steve Henson] | |
215 | ||
800e400d NL |
216 | *) Add new functionality to the bn blinding code: |
217 | - automatic re-creation of the BN_BLINDING parameters after | |
218 | a fixed number of uses (currently 32) | |
219 | - add new function for parameter creation | |
220 | - introduce flags to control the update behaviour of the | |
221 | BN_BLINDING parameters | |
222 | - hide BN_BLINDING structure | |
223 | Add a second BN_BLINDING slot to the RSA structure to improve | |
224 | performance when a single RSA object is shared among several | |
225 | threads. | |
226 | [Nils Larsch] | |
227 | ||
36d16f8e BL |
228 | *) Add support for DTLS. |
229 | [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie] | |
230 | ||
dc0ed30c NL |
231 | *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1) |
232 | to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file() | |
233 | [Walter Goulet] | |
234 | ||
6049399b NL |
235 | *) Remove buggy and incompletet DH cert support from |
236 | ssl/ssl_rsa.c and ssl/s3_both.c | |
237 | [Nils Larsch] | |
238 | ||
12bdb643 NL |
239 | *) Use SHA-1 instead of MD5 as the default digest algorithm for |
240 | the apps/openssl applications. | |
241 | [Nils Larsch] | |
4d94ae00 | 242 | |
41a15c4f BL |
243 | *) Compile clean with "-Wall -Wmissing-prototypes |
244 | -Wstrict-prototypes -Wmissing-declarations -Werror". Currently | |
245 | DEBUG_SAFESTACK must also be set. | |
246 | [Ben Laurie] | |
247 | ||
c9a112f5 | 248 | *) Change ./Configure so that certain algorithms can be disabled by default. |
ecc5ef87 BM |
249 | The new counterpiece to "no-xxx" is "enable-xxx". |
250 | ||
251 | The patented RC5 and MDC2 algorithms will now be disabled unless | |
252 | "enable-rc5" and "enable-mdc2", respectively, are specified. | |
253 | ||
254 | (IDEA remains enabled despite being patented. This is because IDEA | |
255 | is frequently required for interoperability, and there is no license | |
256 | fee for non-commercial use. As before, "no-idea" can be used to | |
257 | avoid this algorithm.) | |
258 | ||
c9a112f5 BM |
259 | [Bodo Moeller] |
260 | ||
6951c23a RL |
261 | *) Add processing of proxy certificates (see RFC 3820). This work was |
262 | sponsored by KTH (The Royal Institute of Technology in Stockholm) and | |
263 | EGEE (Enabling Grids for E-science in Europe). | |
264 | [Richard Levitte] | |
265 | ||
ea681ba8 AP |
266 | *) RC4 performance overhaul on modern architectures/implementations, such |
267 | as Intel P4, IA-64 and AMD64. | |
268 | [Andy Polyakov] | |
269 | ||
401ee37a DSH |
270 | *) New utility extract-section.pl. This can be used specify an alternative |
271 | section number in a pod file instead of having to treat each file as | |
272 | a separate case in Makefile. This can be done by adding two lines to the | |
273 | pod file: | |
274 | ||
275 | =for comment openssl_section:XXX | |
276 | ||
277 | The blank line is mandatory. | |
278 | ||
279 | [Steve Henson] | |
280 | ||
826a42a0 DSH |
281 | *) New arguments -certform, -keyform and -pass for s_client and s_server |
282 | to allow alternative format key and certificate files and passphrase | |
283 | sources. | |
284 | [Steve Henson] | |
285 | ||
5d7c222d DSH |
286 | *) New structure X509_VERIFY_PARAM which combines current verify parameters, |
287 | update associated structures and add various utility functions. | |
288 | ||
289 | Add new policy related verify parameters, include policy checking in | |
290 | standard verify code. Enhance 'smime' application with extra parameters | |
291 | to support policy checking and print out. | |
292 | [Steve Henson] | |
293 | ||
30fe028f GT |
294 | *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3 |
295 | Nehemiah processors. These extensions support AES encryption in hardware | |
296 | as well as RNG (though RNG support is currently disabled). | |
297 | [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov] | |
298 | ||
df11e1e9 GT |
299 | *) Deprecate BN_[get|set]_params() functions (they were ignored internally). |
300 | [Geoff Thorpe] | |
301 | ||
ad500340 AP |
302 | *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented. |
303 | [Andy Polyakov and a number of other people] | |
304 | ||
e14f4aab AP |
305 | *) Improved PowerPC platform support. Most notably BIGNUM assembler |
306 | implementation contributed by IBM. | |
307 | [Suresh Chari, Peter Waltenberg, Andy Polyakov] | |
308 | ||
bcfea9fb GT |
309 | *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public |
310 | exponent rather than 'unsigned long'. There is a corresponding change to | |
311 | the new 'rsa_keygen' element of the RSA_METHOD structure. | |
312 | [Jelte Jansen, Geoff Thorpe] | |
313 | ||
d5f686d8 BM |
314 | *) Functionality for creating the initial serial number file is now |
315 | moved from CA.pl to the 'ca' utility with a new option -create_serial. | |
316 | ||
317 | (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial | |
318 | number file to 1, which is bound to cause problems. To avoid | |
319 | the problems while respecting compatibility between different 0.9.7 | |
320 | patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in | |
321 | CA.pl for serial number initialization. With the new release 0.9.8, | |
322 | we can fix the problem directly in the 'ca' utility.) | |
64674bcc DSH |
323 | [Steve Henson] |
324 | ||
3a87a9b9 GT |
325 | *) Reduced header interdepencies by declaring more opaque objects in |
326 | ossl_typ.h. As a consequence, including some headers (eg. engine.h) will | |
327 | give fewer recursive includes, which could break lazy source code - so | |
328 | this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always, | |
329 | developers should define this symbol when building and using openssl to | |
330 | ensure they track the recommended behaviour, interfaces, [etc], but | |
331 | backwards-compatible behaviour prevails when this isn't defined. | |
332 | [Geoff Thorpe] | |
333 | ||
bf5773fa DSH |
334 | *) New function X509_POLICY_NODE_print() which prints out policy nodes. |
335 | [Steve Henson] | |
336 | ||
216659eb DSH |
337 | *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality. |
338 | This will generate a random key of the appropriate length based on the | |
339 | cipher context. The EVP_CIPHER can provide its own random key generation | |
340 | routine to support keys of a specific form. This is used in the des and | |
341 | 3des routines to generate a key of the correct parity. Update S/MIME | |
342 | code to use new functions and hence generate correct parity DES keys. | |
343 | Add EVP_CHECK_DES_KEY #define to return an error if the key is not | |
344 | valid (weak or incorrect parity). | |
345 | [Steve Henson] | |
346 | ||
e1a27eb3 DSH |
347 | *) Add a local set of CRLs that can be used by X509_verify_cert() as well |
348 | as looking them up. This is useful when the verified structure may contain | |
349 | CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs | |
350 | present unless the new PKCS7_NO_CRL flag is asserted. | |
351 | [Steve Henson] | |
352 | ||
6446e0c3 DSH |
353 | *) Extend ASN1 oid configuration module. It now additionally accepts the |
354 | syntax: | |
355 | ||
356 | shortName = some long name, 1.2.3.4 | |
357 | [Steve Henson] | |
358 | ||
5c98b2ca GT |
359 | *) Reimplemented the BN_CTX implementation. There is now no more static |
360 | limitation on the number of variables it can handle nor the depth of the | |
361 | "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack | |
362 | information can now expand as required, and rather than having a single | |
363 | static array of bignums, BN_CTX now uses a linked-list of such arrays | |
364 | allowing it to expand on demand whilst maintaining the usefulness of | |
365 | BN_CTX's "bundling". | |
366 | [Geoff Thorpe] | |
367 | ||
46ef873f GT |
368 | *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD |
369 | to allow all RSA operations to function using a single BN_CTX. | |
370 | [Geoff Thorpe] | |
371 | ||
4acc3e90 DSH |
372 | *) Preliminary support for certificate policy evaluation and checking. This |
373 | is initially intended to pass the tests outlined in "Conformance Testing | |
374 | of Relying Party Client Certificate Path Processing Logic" v1.07. | |
375 | [Steve Henson] | |
376 | ||
7f663ce4 GT |
377 | *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and |
378 | remained unused and not that useful. A variety of other little bignum | |
379 | tweaks and fixes have also been made continuing on from the audit (see | |
380 | below). | |
381 | [Geoff Thorpe] | |
382 | ||
875a644a RL |
383 | *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with |
384 | associated ASN1, EVP and SSL functions and old ASN1 macros. | |
7f663ce4 | 385 | [Richard Levitte] |
875a644a | 386 | |
b6358c89 GT |
387 | *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results, |
388 | and this should never fail. So the return value from the use of | |
389 | BN_set_word() (which can fail due to needless expansion) is now deprecated; | |
390 | if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro. | |
391 | [Geoff Thorpe] | |
392 | ||
9e051bac GT |
393 | *) BN_CTX_get() should return zero-valued bignums, providing the same |
394 | initialised value as BN_new(). | |
395 |
