5 | Changes between 0.9.4 and 0.9.5 [xx XXX 1999] |
6 | ||
9868232a DSH |
7 | *) Fixes and enhancements to the 'x509' utility. It allowed a message |
8 | digest to be passed on the command line but it only used this | |
9 | parameter when signing a certificate. Modified so all relevant | |
10 | operations are affected by the digest parameter including the | |
11 | -fingerprint and -x509toreq options. Also -x509toreq choked if a | |
12 | DSA key was used because it didn't fix the digest. | |
13 | [Steve Henson] | |
14 | ||
51630a37 DSH |
15 | *) Initial certificate chain verify code. Currently tests the untrusted |
16 | certificates for consistency with the verify purpose (which is set | |
17 | when the X509_STORE_CTX structure is set up) and checks the pathlength. | |
18 | ||
19 | There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour: | |
20 | this is because when it is finally working it will reject chains with | |
21 | invalid extensions whereas every previous version of OpenSSL and SSLeay | |
22 | made no checks at all. | |
23 | ||
24 | Trust code: checks the root CA for the relevant trust settings. Trust | |
25 | settings have an initial value consistent with the verify purpose: e.g. | |
26 | if the verify purpose is for SSL client use it expects the CA to be | |
27 | trusted for SSL client use. However the default value can be changed to | |
28 | permit custom trust settings: one example of this would be to only trust | |
29 | certificates from a specific "secure" set of CAs. | |
11262391 DSH |
30 | |
31 | Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions | |
32 | which should be used for version portability: especially since the | |
33 | verify structure is likely to change more often now. | |
d4cec6a1 DSH |
34 | |
35 | Two new options to the verify program: -untrusted allows a set of | |
36 | untrusted certificates to be passed in and -purpose which sets the | |
37 | intended purpose of the certificate. If a purpose is set then the | |
38 | new chain verify code is used to check extension consistency. | |
11262391 DSH |
39 | [Steve Henson] |
40 | ||
41 | *) Support for the authority information access extension. | |
6d3724d3 DSH |
42 | [Steve Henson] |
43 | ||
52664f50 DSH |
44 | *) Modify RSA and DSA PEM read routines to transparently handle |
45 | PKCS#8 format private keys. New *_PUBKEY_* functions that handle | |
46 | public keys in a format compatible with certificate | |
47 | SubjectPublicKeyInfo structures. Unfortunately there were already | |
48 | functions called *_PublicKey_* which used various odd formats so | |
49 | these are retained for compatability: however the DSA variants were | |
50 | never in a public release so they have been deleted. Changed dsa/rsa | |
51 | utilities to handle the new format: note no releases ever handled public | |
52 | keys so we should be OK. | |
53 | ||
54 | The primary motivation for this change is to avoid the same fiasco | |
55 | that dogs private keys: there are several incompatible private key | |
56 | formats some of which are standard and some OpenSSL specific and | |
57 | require various evil hacks to allow partial transparent handling and | |
58 | even then it doesn't work with DER formats. Given the option anything | |
59 | other than PKCS#8 should be dumped: but the other formats have to | |
60 | stay in the name of compatability. | |
61 | ||
62 | With public keys and the benefit of hindsight one standard format | |
63 | is used which works with EVP_PKEY, RSA or DSA structures: though | |
64 | it clearly returns an error if you try to read the wrong kind of key. | |
65 | ||
66 | Added a -pubkey option to the 'x509' utility to output the public key. | |
67 | Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() and add | |
68 | EVP_PKEY_rset_*() functions that do the same as the EVP_PKEY_assign_*() | |
69 | except they up the reference count of the added key (they don't "swallow" | |
70 | the supplied key). | |
71 | [Steve Henson] | |
72 | ||
73 | *) Fixes to crypto/x509/by_file.c the code to read in certificates and | |
74 | CRLs would fail if the file contained no certificates or no CRLs: | |
75 | added a new function to read in both types and return the number | |
76 | read: this means that if none are read it will be an error. The | |
77 | DER versions of the certificate and CRL reader would always fail | |
78 | because it isn't possible to mix certificates and CRLs in DER format | |
79 | without choking one or the other routine. Changed this to just read | |
80 | a certificate: this is the best we can do. Also modified the code | |
81 | in apps/verify.c to take notice of return codes: it was previously | |
82 | attempting to read in certificates from NULL pointers and ignoring | |
83 | any errors: this is one reason why the cert and CRL reader seemed | |
84 | to work. It doesn't check return codes from the default certificate | |
85 | routines: these may well fail if the certificates aren't installed. | |
86 | [Steve Henson] | |
87 | ||
a716d727 DSH |
88 | *) Code to support otherName option in GeneralName. |
89 | [Steve Henson] | |
90 | ||
f76d8c47 DSH |
91 | *) First update to verify code. Change the verify utility |
92 | so it warns if it is passed a self signed certificate: | |
93 | for consistency with the normal behaviour. X509_verify | |
94 | has been modified to it will now verify a self signed | |
95 | certificate if *exactly* the same certificate appears | |
96 | in the store: it was previously impossible to trust a | |
97 | single self signed certificate. This means that: | |
98 | openssl verify ss.pem | |
99 | now gives a warning about a self signed certificate but | |
100 | openssl verify -CAfile ss.pem ss.pem | |
101 | is OK. | |
102 | [Steve Henson] | |
103 | ||
b1fe6ca1 BM |
104 | *) For servers, store verify_result in SSL_SESSION data structure |
105 | (and add it to external session representation). | |
106 | This is needed when client certificate verifications fails, | |
107 | but an application-provided verification callback (set by | |
108 | SSL_CTX_set_cert_verify_callback) allows accepting the session | |
109 | anyway (i.e. leaves x509_store_ctx->error != X509_V_OK | |
110 | but returns 1): When the session is reused, we have to set | |
111 | ssl->verify_result to the appropriate error code to avoid | |
112 | security holes. | |
113 | [Bodo Moeller, problem pointed out by Lutz Jaenicke] | |
114 | ||
91895a59 DSH |
115 | *) Fix a bug in the new PKCS#7 code: it didn't consider the |
116 | case in PKCS7_dataInit() where the signed PKCS7 structure | |
117 | didn't contain any existing data because it was being created. | |
f76d8c47 | 118 | [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson] |
91895a59 | 119 | |
fd699ac5 DSH |
120 | *) Add a salt to the key derivation routines in enc.c. This |
121 | forms the first 8 bytes of the encrypted file. Also add a | |
122 | -S option to allow a salt to be input on the command line. | |
123 | [Steve Henson] | |
124 | ||
e947f396 DSH |
125 | *) New function X509_cmp(). Oddly enough there wasn't a function |
126 | to compare two certificates. We do this by working out the SHA1 | |
127 | hash and comparing that. X509_cmp() will be needed by the trust | |
128 | code. | |
129 | [Steve Henson] | |
130 | ||
b7cfcfb7 MC |
131 | *) Correctly increment the reference count in the SSL_SESSION pointer |
132 | returned from SSL_get_session(). | |
133 | [Geoff Thorpe <geoff@eu.c2.net>] | |
134 | ||
06556a17 DSH |
135 | *) Fix for 'req': it was adding a null to request attributes. |
136 | Also change the X509_LOOKUP and X509_INFO code to handle | |
137 | certificate auxiliary information. | |
138 | [Steve Henson] | |
139 | ||
a0e9f529 DSH |
140 | *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document |
141 | the 'enc' command. | |
142 | [Steve Henson] | |
143 | ||
71d7526b RL |
144 | *) Add the possibility to add extra information to the memory leak |
145 | detecting output, to form tracebacks, showing from where each | |
146 | allocation was originated. Also updated sid code to be multi- | |
147 | thread-safe. | |
148 | [Richard Levitte] | |
149 | ||
a0e9f529 | 150 | *) Add options -text and -noout to pkcs7 utility and delete the |
954ef7ef DSH |
151 | encryption options which never did anything. Update docs. |
152 | [Steve Henson] | |
153 | ||
af29811e DSH |
154 | *) Add options to some of the utilities to allow the pass phrase |
155 | to be included on either the command line (not recommended on | |
156 | OSes like Unix) or read from the environment. Update the | |
157 | manpages and fix a few bugs. | |
158 | [Steve Henson] | |
159 | ||
aba3e65f DSH |
160 | *) Add a few manpages for some of the openssl commands. |
161 | [Steve Henson] | |
162 | ||
a0ad17bb DSH |
163 | *) Fix the -revoke option in ca. It was freeing up memory twice, |
164 | leaking and not finding already revoked certificates. | |
165 | [Steve Henson] | |
166 | ||
ce1b4fe1 DSH |
167 | *) Extensive changes to support certificate auxiliary information. |
168 | This involves the use of X509_CERT_AUX structure and X509_AUX | |
169 | functions. An X509_AUX function such as PEM_read_X509_AUX() | |
170 | can still read in a certificate file in the usual way but it | |
171 | will also read in any additional "auxiliary information". By | |
172 | doing things this way a fair degree of compatability can be | |
173 | retained: existing certificates can have this information added | |
174 | using the new 'x509' options. | |
175 | ||
176 | Current auxiliary information includes an "alias" and some trust | |
177 | settings. The trust settings will ultimately be used in enhanced | |
178 | certificate chain verification routines: currently a certificate | |
179 | can only be trusted if it is self signed and then it is trusted | |
180 | for all purposes. | |
181 | [Steve Henson] | |
182 | ||
ce2c95b2 MC |
183 | *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). The |
184 | problem was that one of the replacement routines had not been working since | |
185 | SSLeay releases. For now the offending routine has been replaced with | |
186 | non-optimised assembler. Even so, this now gives around 95% performance | |
187 | improvement for 1024 bit RSA signs. | |
188 | [Mark Cox] | |
189 | ||
9716a8f9 DSH |
190 | *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2 |
191 | handling. Most clients have the effective key size in bits equal to | |
192 | the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key. | |
193 | A few however don't do this and instead use the size of the decrypted key | |
194 | to determine the RC2 key length and the AlgorithmIdentifier to determine | |
195 | the effective key length. In this case the effective key lenth can still | |
196 | be 40 bits but the key length can be 168 bits for example. This is fixed | |
197 | by manually forcing an RC2 key into the EVP_PKEY structure because the | |
198 | EVP code can't currently handle unusual RC2 key sizes: it always assumes | |
199 | the key length and effective key length are equal. | |
200 | [Steve Henson] | |
201 | ||
74400f73 DSH |
202 | *) Add a bunch of functions that should simplify the creation of |
203 | X509_NAME structures. Now you should be able to do: | |
204 | X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0); | |
205 | and have it automatically work out the correct field type and fill in | |
206 | the structures. The more adventurous can try: | |
207 | X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0); | |
208 | and it will (hopefully) work out the correct multibyte encoding. | |
209 | [Steve Henson] | |
210 | ||
211 | *) Change the 'req' utility to use the new field handling and multibyte | |
212 | copy routines. Before the DN field creation was handled in an ad hoc | |
213 | way in req, ca, and x509 which was rather broken and didn't support | |
214 | BMPStrings or UTF8Strings. Since some software doesn't implement | |
215 | BMPStrings or UTF8Strings yet, they can be enabled using the config file | |
216 | using the dirstring_type option. See the new comment in the default | |
217 | openssl.cnf for more info. | |
218 | [Steve Henson] | |
219 | ||
c1e744b9 | 220 | *) Make crypto/rand/md_rand.c more robust: |
62ac2938 | 221 | - Assure unique random numbers after fork(). |
c1e744b9 BM |
222 | - Make sure that concurrent threads access the global counter and |
223 | md serializably so that we never lose entropy in them | |
224 | or use exactly the same state in multiple threads. | |
225 | Access to the large state is not always serializable because | |
226 | the additional locking could be a performance killer, and | |
227 | md should be large enough anyway. | |
228 | [Bodo Moeller] | |
229 | ||
a31011e8 BM |
230 | *) New file apps/app_rand.c with commonly needed functionality |
231 | for handling the random seed file. | |
232 | ||
233 | Use the random seed file in some applications that previously did not: | |
234 | ca, | |
235 | dsaparam -genkey (which also ignored its `-rand' option), | |
236 | s_client, | |
237 | s_server, | |
238 | x509 (when signing). | |
239 | Except on systems with /dev/urandom, it is crucial to have a random | |
240 | seed file at least for key creation, DSA signing, and for DH exchanges; | |
99e87569 | 241 | for RSA signatures we could do without one. |
a31011e8 BM |
242 | |
243 | gendh and gendsa (unlike genrsa) used to read only the first byte | |
244 | of each file listed in the `-rand' option. The function as previously | |
245 | found in genrsa is now in app_rand.c and is used by all programs | |
246 | that support `-rand'. | |
247 | [Bodo Moeller] | |
248 | ||
249 | *) In RAND_write_file, use mode 0600 for creating files; | |
250 | don't just chmod when it may be too late. | |
251 | [Bodo Moeller] | |
252 | ||
253 | *) Report an error from X509_STORE_load_locations | |
254 | when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed. | |
255 | [Bill Perry] | |
256 | ||
462f79ec DSH |
257 | *) New function ASN1_mbstring_copy() this copies a string in either |
258 | ASCII, Unicode, Universal (4 bytes per character) or UTF8 format | |
259 | into an ASN1_STRING type. A mask of permissible types is passed | |
260 | and it chooses the "minimal" type to use or an error if not type | |
261 | is suitable. | |
262 | [Steve Henson] | |
263 | ||
08e9c1af DSH |
264 | *) Add function equivalents to the various macros in asn1.h. The old |
265 | macros are retained with an M_ prefix. Code inside the library can | |
266 | use the M_ macros. External code (including the openssl utility) | |
267 | should *NOT* in order to be "shared library friendly". | |
268 | [Steve Henson] | |
269 | ||
673b102c DSH |
270 | *) Add various functions that can check a certificate's extensions |
271 | to see if it usable for various purposes such as SSL client, | |
272 | server or S/MIME and CAs of these types. This is currently | |
273 | VERY EXPERIMENTAL but will ultimately be used for certificate chain | |
274 | verification. Also added a -purpose flag to x509 utility to | |
275 | print out all the purposes. | |
276 | [Steve Henson] | |
277 | ||
56a3fec1 DSH |
278 | *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated |
279 | functions. | |
280 | [Steve Henson] | |
281 | ||
4654ef98 DSH |
282 | *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search |
283 | for, obtain and decode and extension and obtain its critical flag. | |
284 | This allows all the necessary extension code to be handled in a | |
285 | single function call. | |
286 | [Steve Henson] | |
287 | ||
7e102e28 AP |
288 | *) RC4 tune-up featuring 30-40% performance improvement on most RISC |
289 | platforms. See crypto/rc4/rc4_enc.c for further details. | |
290 | [Andy Polyakov] | |
291 | ||
d71c6bc5 DSH |
292 | *) New -noout option to asn1parse. This causes no output to be produced |
293 | its main use is when combined with -strparse and -out to extract data | |
294 | from a file (which may not be in ASN.1 format). | |
295 | [Steve Henson] | |
296 | ||
2d681b77 DSH |
297 | *) Fix for pkcs12 program. It was hashing an invalid certificate pointer |
298 | when producing the local key id. | |
299 | [Richard Levitte <levitte@stacken.kth.se>] | |
300 | ||
3908cdf4 DSH |
301 | *) New option -dhparam in s_server. This allows a DH parameter file to be |
302 | stated explicitly. If it is not stated then it tries the first server | |
303 | certificate file. The previous behaviour hard coded the filename | |
304 | "server.pem". | |
305 | [Steve Henson] | |
306 | ||
3ea23631 DSH |
307 | *) Add -pubin and -pubout options to the rsa and dsa commands. These allow |
308 | a public key to be input or output. For example: | |
309 | openssl rsa -in key.pem -pubout -out pubkey.pem | |
310 | Also added necessary DSA public key functions to handle this. | |
311 | [Steve Henson] | |
312 | ||
393f2c65 DSH |
313 | *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained |
314 | in the message. This was handled by allowing | |
315 | X509_find_by_issuer_and_serial() to tolerate a NULL passed to it. | |
316 | [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>] | |
317 | ||
318 | *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null | |
319 | to the end of the strings whereas this didn't. This would cause problems | |
320 | if strings read with d2i_ASN1_bytes() were later modified. | |
321 | [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>] | |
322 | ||
4579dd5d DSH |
323 | *) Fix for base64 decode bug. When a base64 bio reads only one line of |
324 | data and it contains EOF it will end up returning an error. This is | |
325 | caused by input 46 bytes long. The cause is due to the way base64 | |
326 | BIOs find the start of base64 encoded data. They do this by trying a | |
327 | trial decode on each line until they find one that works. When they | |
328 | do a flag is set and it starts again knowing it can pass all the | |
329 | data directly through the decoder. Unfortunately it doesn't reset | |
330 | the context it uses. This means that if EOF is reached an attempt | |
331 | is made to pass two EOFs through the context and this causes the | |
332 | resulting error. This can also cause other problems as well. As is | |
333 | usual with these problems it takes *ages* to find and the fix is | |
334 | trivial: move one line. | |
335 | [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ] | |
336 | ||
06f4536a DSH |
337 | *) Ugly workaround to get s_client and s_server working under Windows. The |
338 | old code wouldn't work because it needed to select() on sockets and the | |
339 | tty (for keypresses and to see if data could be written). Win32 only | |
340 | supports select() on sockets so we select() with a 1s timeout on the | |
341 | sockets and then see if any characters are waiting to be read, if none | |
342 | are present then we retry, we also assume we can always write data to | |
343 | the tty. This isn't nice because the code then blocks until we've | |
344 | received a complete line of data and it is effectively polling the | |
345 | keyboard at 1s intervals: however it's quite a bit better than not | |
346 | working at all :-) A dedicated Windows application might handle this | |
347 | with an event loop for example. | |
348 | [Steve Henson] | |
349 | ||
1c80019a DSH |
350 | *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign |
351 | and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions | |
352 | will be called when RSA_sign() and RSA_verify() are used. This is useful | |
353 | if rsa_pub_dec() and rsa_priv_enc() equivalents are not available. | |
354 | For this to work properly RSA_public_decrypt() and RSA_private_encrypt() | |
355 | should *not* be used: RSA_sign() and RSA_verify() must be used instead. | |
356 | This necessitated the support of an extra signature type NID_md5_sha1 | |
357 | for SSL signatures and modifications to the SSL library to use it instead | |
358 | of calling RSA_public_decrypt() and RSA_private_encrypt(). | |
359 | [Steve Henson] | |
360 | ||
090d848e DSH |
361 | *) Add new -verify -CAfile and -CApath options to the crl program, these |
362 | will lookup a CRL issuers certificate and verify the signature in a | |
363 | similar way to the verify program. Tidy up the crl program so it | |
364 | no longer acesses structures directly. Make the ASN1 CRL parsing a bit | |
365 | less strict. It will now permit CRL extensions even if it is not | |
366 | a V2 CRL: this will allow it to tolerate some broken CRLs. | |
367 | [Steve Henson] | |
368 | ||
396f6314 BM |
369 | *) Initialize all non-automatic variables each time one of the openssl |
370 | sub-programs is started (this is necessary as they may be started | |
371 | multiple times from the "OpenSSL>" prompt). | |
372 | [Lennart Bang, Bodo Moeller] | |
373 | ||
4a61a64f DSH |
374 | *) Preliminary compilation option RSA_NULL which disables RSA crypto without |
375 | removing all other RSA functionality (this is what NO_RSA does). This | |
376 | is so (for example) those in the US can disable those operations covered | |
377 | by the RSA patent while allowing storage and parsing of RSA keys and RSA | |
378 | key generation. | |
379 | [Steve Henson] | |
380 | ||
c1082a90 | 381 | *) Non-copying interface to BIO pairs. |
6f7af152 | 382 | (still largely untested) |
c1082a90 BM |
383 | [Bodo Moeller] |
384 | ||
a785abc3 DSH |
385 | *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive |
386 | ASCII string. This was handled independently in various places before. | |
387 | [Steve Henson] | |
388 | ||
aef838fc DSH |
389 | *) New functions UTF8_getc() and UTF8_putc() that parse and generate |
390 | UTF8 strings a character at a time. | |
391 | [Steve Henson] | |

074309b7 BM |
393 | *) Use client_version from client hello to select the protocol |
394 | (s23_srvr.c) and for RSA client key exchange verification | |
395 | (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications. | |
396 | [Bodo Moeller] | |
397 | ||
8ce97163 DSH |
398 | *) Add various utility functions to handle SPKACs, these were previously |
399 | handled by poking round in the structure internals. Added new function | |
400 | NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to | |
401 | print, verify and generate SPKACs. Based on an original idea from | |
402 | Massimiliano Pala <madwolf@comune.modena.it> but extensively modified. | |
403 | [Steve Henson] | |
404 | ||
2d4287da AP |
405 | *) RIPEMD160 is operational on all platforms and is back in 'make test'. |
406 | [Andy Polyakov] | |
407 | ||
87a25f90 DSH |
408 | *) Allow the config file extension section to be overwritten on the |
409 | command line. Based on an original idea from Massimiliano Pala | |
410 | <madwolf@comune.modena.it>. The new option is called -extensions | |
411 | and can be applied to ca, req and x509. Also -reqexts to override | |
412 | the request extensions in req and -crlexts to override the crl extensions | |
413 | in ca. | |
414 | [Steve Henson] | |
415 | ||
f9150e54 DSH |
416 | *) Add new feature to the SPKAC handling in ca. Now you can include |
417 | the same field multiple times by preceding it by "XXXX." for example: | |
418 | 1.OU="Unit name 1" | |
419 | 2.OU="Unit name 2" | |
420 | this is the same syntax as used in the req config file. | |
421 | [Steve Henson] | |
422 | ||
c79b16e1 DSH |
423 | *) Allow certificate extensions to be added to certificate requests. These |
424 | are specified in a 'req_extensions' option of the req section of the | |
425 | config file. They can be printed out with the -text option to req but | |
426 | are otherwise ignored at present. | |
427 | [Steve Henson] | |
428 | ||
96c2201b | 429 | *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first |
0f7e6fe1 | 430 | data read consists of only the final block it would not decrypted because |
7b65c329 DSH |
431 | EVP_CipherUpdate() would correctly report zero bytes had been decrypted. |
432 | A misplaced 'break' also meant the decrypted final block might not be | |
433 | copied until the next read. | |
434 | [Steve Henson] | |
435 | ||
13066cee DSH |
436 | *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added |
437 | a few extra parameters to the DH structure: these will be useful if | |
438 | for example we want the value of 'q' or implement X9.42 DH. | |
439 | [Steve Henson] | |
440 | ||
c0711f7f DSH |
441 | *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and |
442 | provides hooks that allow the default DSA functions or functions on a | |
443 | "per key" basis to be replaced. This allows hardware acceleration and | |
444 | hardware key storage to be handled without major modification to the | |
445 | library. Also added low level modexp hooks and CRYPTO_EX structure and | |
446 | associated functions. | |
447 | [Steve Henson] | |
448 | ||
8484721a DSH |
449 | *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO |
450 | as "read only": it can't be written to and the buffer it points to will | |
451 | not be freed. Reading from a read only BIO is much more efficient than | |
452 | a normal memory BIO. This was added because there are several times when | |
453 | an area of memory needs to be read from a BIO. The previous method was | |
454 | to create a memory BIO and write the data to it, this results in two | |
455 | copies of the data and an O(n^2) reading algorithm. There is a new | |
456 | function BIO_new_mem_buf() which creates a read only memory BIO from | |
457 | an area of memory. Also modified the PKCS#7 routines to use read only | |
458 | memory BIOSs. | |
459 | [Steve Henson] | |
460 | ||
de1915e4 BM |
461 | *) Bugfix: ssl23_get_client_hello did not work properly when called in |
462 | state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of | |
463 | a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read, | |
464 | but a retry condition occured while trying to read the rest. | |
465 | [Bodo Moeller] | |
466 | ||
c6c34506 DSH |
467 | *) The PKCS7_ENC_CONTENT_new() function was setting the content type as |
468 | NID_pkcs7_encrypted by default: this was wrong since this should almost | |
469 | always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle | |
470 | the encrypted data type: this is a more sensible place to put it and it | |
471 | allows the PKCS#12 code to be tidied up that duplicated this | |
472 | functionality. | |
473 | [Steve Henson] | |
474 | ||
fd520577 DSH |
475 | *) Changed obj_dat.pl script so it takes its input and output files on |
476 | the command line. This should avoid shell escape redirection problems | |
477 | under Win32. | |
478 | [Steve Henson] | |
479 | ||
87c49f62 | 480 | *) Initial support for certificate extension requests, these are included |
fd520577 DSH |
481 | in things like Xenroll certificate requests. Included functions to allow |
482 | extensions to be obtained and added. | |
87c49f62 DSH |
483 | [Steve Henson] |
484 | ||
1b1a6e78 BM |
485 | *) -crlf option to s_client and s_server for sending newlines as |
486 | CRLF (as required by many protocols). | |
487 | [Bodo Moeller] | |
488 | ||
9a577e29 | 489 | Changes between 0.9.3a and 0.9.4 [09 Aug 1999] |
dfbaf956 | 490 | |
9a577e29 | 491 | *) Install libRSAglue.a when OpenSSL is built with RSAref. |
dfbaf956 | 492 | [Ralf S. Engelschall] |
74678cc2 | 493 | |
96395158 RE |
494 | *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency. |
495 | [Andrija Antonijevic <TheAntony2@bigfoot.com>] | |
496 | ||
ed7f60fb DSH |
497 | *) Fix -startdate and -enddate (which was missing) arguments to 'ca' |
498 | program. | |
499 | [Steve Henson] | |
500 | ||
48c843c3 BM |
501 | *) New function DSA_dup_DH, which duplicates DSA parameters/keys as |
502 | DH parameters/keys (q is lost during that conversion, but the resulting | |
503 | DH parameters contain its length). | |
504 | ||
505 | For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is | |
506 | much faster than DH_generate_parameters (which creates parameters | |
507 | where p = 2*q + 1), and also the smaller q makes DH computations | |
508 | much more efficient (160-bit exponentiation instead of 1024-bit | |
509 | exponentiation); so this provides a convenient way to support DHE | |
510 | ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of | |
511 | utter importance to use | |
512 | SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); | |
513 | or | |
514 | SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); | |
515 | when such DH parameters are used, because otherwise small subgroup | |
516 | attacks may become possible! | |
517 | [Bodo Moeller] | |
518 | ||
519 | *) Avoid memory leak in i2d_DHparams. | |
520 | [Bodo Moeller] | |
521 | ||
922180d7 DSH |
522 | *) Allow the -k option to be used more than once in the enc program: |
523 | this allows the same encrypted message to be read by multiple recipients. | |
524 | [Steve Henson] | |
525 | ||
3e3d2ea2 DSH |
526 | *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts |
527 | an ASN1_OBJECT to a text string. If the "no_name" parameter is set then | |
528 | it will always use the numerical form of the OID, even if it has a short | |
529 | or long name. | |
530 | [Steve Henson] | |
531 | ||
770d19b8 DSH |
532 | *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp |
533 | method only got called if p,q,dmp1,dmq1,iqmp components were present, | |
534 | otherwise bn_mod_exp was called. In the case of hardware keys for example | |
535 | no private key components need be present and it might store extra data | |
96c2201b BM |
536 | in the RSA structure, which cannot be accessed from bn_mod_exp. |
537 | By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for | |
538 | private key operations. | |
770d19b8 DSH |
539 | [Steve Henson] |
540 | ||
a0618e3e AP |
541 | *) Added support for SPARC Linux. |
542 | [Andy Polyakov] | |
543 | ||
74678cc2 BM |
544 | *) pem_password_cb function type incompatibly changed from |
545 | typedef int pem_password_cb(char *buf, int size, int rwflag); | |
546 | to | |
547 | ....(char *buf, int size, int rwflag, void *userdata); | |
548 | so that applications can pass data to their callbacks: | |
549 | The PEM[_ASN1]_{read,write}... functions and macros now take an | |
550 | additional void * argument, which is just handed through whenever | |
551 | the password callback is called. | |
96c2201b | 552 | [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller] |
74678cc2 BM |
553 | |
554 | New function SSL_CTX_set_default_passwd_cb_userdata. | |
555 | ||
556 | Compatibility note: As many C implementations push function arguments | |
557 | onto the stack in reverse order, the new library version is likely to | |
558 | interoperate with programs that have been compiled with the old | |
559 | pem_password_cb definition (PEM_whatever takes some data that | |
560 | happens to be on the stack as its last argument, and the callback | |
561 | just ignores this garbage); but there is no guarantee whatsoever that | |
562 | this will work. | |
0cceb1c7 | 563 | |
664b9985 BM |
564 | *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=... |
565 | (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused | |
566 | problems not only on Windows, but also on some Unix platforms. | |
2e0fc875 | 567 | To avoid problematic command lines, these definitions are now in an |
57119943 BM |
568 | auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl |
569 | for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds). | |
664b9985 BM |
570 | [Bodo Moeller] |
571 | ||
7363455f AP |
572 | *) MIPS III/IV assembler module is reimplemented. |
573 | [Andy Polyakov] | |
574 | ||
6434450c UM |
575 | *) More DES library cleanups: remove references to srand/rand and |
576 | delete an unused file. | |
577 |
