c5e8580e | 4 | Changes between 0.9.6 and 0.9.7 [xx XXX 2000] |
a43cf9fa | 5 | |
ccb08f98 DSH |
6 | *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string() |
7 | set string type: to handle setting ASN1_TIME structures. Fix ca | |
8 | utility to correctly initialize revocation date of CRLs. | |
9 | [Steve Henson] | |
10 | ||
836f9960 LJ |
11 | *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override |
12 | the clients preferred ciphersuites and rather use its own preferences. | |
13 | Should help to work around M$ SGC (Server Gated Cryptography) bug in | |
14 | Internet Explorer by ensuring unchanged hash method during stepup. | |
15 | [Lutz Jaenicke] | |
16 | ||
c47c6196 DSH |
17 | *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael |
18 | to aes and add a new 'exist' option to print out symbols that don't | |
19 | appear to exist. | |
20 | [Steve Henson] | |
21 | ||
8c950429 DSH |
22 | *) Additional options to ocsp utility to allow flags to be set and |
23 | additional certificates supplied. | |
24 | [Steve Henson] | |
25 | ||
9235adbf RL |
26 | *) Add the option -VAfile to 'openssl ocsp', so the user can give the |
27 | OCSP client a number of certificate to only verify the response | |
28 | signature against. | |
29 | [Richard Levitte] | |
30 | ||
57e7d3ce UM |
31 | *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent |
32 | Bleichenbacher's DSA attack. | |
35ed8cb8 | 33 | [Ulf Moeller, Bodo Moeller] |
57e7d3ce | 34 | |
deb2c1a1 DSH |
35 | *) Update Rijndael code to version 3.0 and change EVP AES ciphers to |
36 | handle the new API. Currently only ECB, CBC modes supported. Add new | |
37 | AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites | |
38 | for TLS" draft-ietf-tls-ciphersuite-03.txt. | |
39 | [Ben Laurie, Steve Henson] | |
40 | ||
9eea2be6 BM |
41 | *) In the NCONF_...-based implementations for CONF_... queries |
42 | (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using | |
43 | a temporary CONF structure with the data component set to NULL | |
44 | (which gives segmentation faults in lh_retrieve). | |
45 | Instead, use NULL for the CONF pointer in CONF_get_string and | |
46 | CONF_get_number (which may use environment variables) and directly | |
47 | return NULL from CONF_get_section. | |
48 | [Bodo Moeller] | |
49 | ||
741a9690 UM |
50 | *) Fix potential buffer overrun for EBCDIC. |
51 | [Ulf Moeller] | |
52 | ||
26e083cc DSH |
53 | *) New function OCSP_copy_nonce() to copy nonce value (if present) from |
54 | request to response. | |
55 | [Steve Henson] | |
56 | ||
02e4fbed DSH |
57 | *) Functions for OCSP responders. OCSP_request_onereq_count(), |
58 | OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info() | |
59 | extract information from a certificate request. OCSP_response_create() | |
60 | creates a response and optionally adds a basic response structure. | |
61 | OCSP_basic_add1_status() adds a complete single response to a basic | |
62 | reponse and returns the OCSP_SINGLERESP structure just added (to allow | |
63 | extensions to be included for example). OCSP_basic_add1_cert() adds a | |
64 | certificate to a basic response and OCSP_basic_sign() signs a basic | |
65 | response with various flags. New helper functions ASN1_TIME_check() | |
66 | (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime() | |
67 | (converts ASN1_TIME to GeneralizedTime). | |
68 | [Steve Henson] | |
69 | ||
88ce56f8 DSH |
70 | *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}() |
71 | in a single operation. X509_get0_pubkey_bitstr() extracts the public_key | |
72 | structure from a certificate. X509_pubkey_digest() digests tha public_key | |
73 | contents: this is used in various key identifiers. | |
74 | [Steve Henson] | |
75 | ||
8cff6331 DSH |
76 | *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign |
77 | keyUsage if basicConstraints absent for a CA. | |
78 | [Steve Henson] | |
79 | ||
903872d6 RL |
80 | *) Make SMIME_write_PKCS7() write mail header values with a format that |
81 | is more generally accepted (no spaces before the semicolon), since | |
82 | some programs can't parse those values properly otherwise. Also make | |
83 | sure BIO's that break lines after each write do not create invalid | |
84 | headers. | |
85 | [Richard Levitte] | |
86 | ||
b8470240 DSH |
87 | *) Make sk_sort() tolerate a NULL argument. |
88 | [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>] | |
89 | ||
50d51991 DSH |
90 | *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates |
91 | passed by the function are trusted implicitly. If any of them signed the | |
92 | reponse then it is assumed to be valid and is not verified. | |
93 | [Steve Henson] | |
94 | ||
a342cc5a DSH |
95 | *) Zero the premaster secret after deriving the master secret in |
96 | DH ciphersuites. | |
97 | [Steve Henson] | |
98 | ||
a43cf9fa DSH |
99 | *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT |
100 | to data. This was previously part of the PKCS7 ASN1 code. This | |
101 | was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures. | |
102 | [Steve Henson, reported by Kenneth R. Robinette | |
103 | <support@securenetterm.com>] | |
104 | ||
105 | *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1 | |
106 | routines: without these tracing memory leaks is very painful. | |
107 | Fix leaks in PKCS12 and PKCS7 routines. | |
108 | [Steve Henson] | |
109 | ||
75802000 UM |
110 | *) Fix for Irix with NO_ASM. |
111 | ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>] | |
112 | ||
ae0665b8 BM |
113 | *) Add some EVP_add_digest_alias registrations (as found in |
114 | OpenSSL_add_all_digests()), to SSL_library_init() | |
115 | aka OpenSSL_add_ssl_algorithms(). This provides improved | |
116 | compatibility with peers using X.509 certificates | |
117 | with unconventional AlgorithmIdentifier OIDs. | |
118 | [Bodo Moeller] | |
119 | ||
893b76c5 UM |
120 | *) ./config script fixes. |
121 | [Ulf Moeller, Richard Levitte] | |
122 | ||
ba8e2824 DSH |
123 | *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new(). |
124 | Previously it initialised the 'type' argument to V_ASN1_UTCTIME which | |
125 | effectively meant GeneralizedTime would never be used. Now it | |
126 | is initialised to -1 but X509_time_adj() now has to check the value | |
127 | and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or | |
128 | V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime. | |
129 | [Steve Henson, reported by Kenneth R. Robinette | |
130 | <support@securenetterm.com>] | |
131 | ||
8e8972bb DSH |
132 | *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously |
133 | result in a zero length in the ASN1_INTEGER structure which was | |
134 | not consistent with the structure when d2i_ASN1_INTEGER() was used | |
135 | and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER() | |
136 | to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER() | |
137 | where it did not print out a minus for negative ASN1_INTEGER. | |
138 | [Steve Henson] | |
139 | ||
57108f0a BM |
140 | *) Fix 'openssl passwd -1'. |
141 | [Bodo Moeller] | |
142 | ||
73758d43 DSH |
143 | *) Add summary printout to ocsp utility. The various functions which |
144 | convert status values to strings have been renamed to: | |
145 | OCSP_response_status_str(), OCSP_cert_status_str() and | |
146 | OCSP_crl_reason_str() and are no longer static. New options | |
147 | to verify nonce values and to disable verification. OCSP response | |
148 | printout format cleaned up. | |
149 | [Steve Henson] | |
150 | ||
e8af92fc DSH |
151 | *) Add additional OCSP certificate checks. These are those specified |
152 | in RFC2560. This consists of two separate checks: the CA of the | |
153 | certificate being checked must either be the OCSP signer certificate | |
154 | or the issuer of the OCSP signer certificate. In the latter case the | |
155 | OCSP signer certificate must contain the OCSP signing extended key | |
156 | usage. This check is performed by attempting to match the OCSP | |
157 | signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash | |
158 | in the OCSP_CERTID structures of the response. | |
159 | [Steve Henson] | |
160 | ||
81f169e9 DSH |
161 | *) Initial OCSP certificate verification added to OCSP_basic_verify() |
162 | and related routines. This uses the standard OpenSSL certificate | |
163 | verify routines to perform initial checks (just CA validity) and | |
164 | to obtain the certificate chain. Then additional checks will be | |
165 | performed on the chain. Currently the root CA is checked to see | |
166 | if it is explicitly trusted for OCSP signing. This is used to set | |
167 | a root CA as a global signing root: that is any certificate that | |
168 | chains to that CA is an acceptable OCSP signing certificate. | |
169 | [Steve Henson] | |
170 | ||
dfebac32 BM |
171 | *) New '-extfile ...' option to 'openssl ca' for reading X.509v3 |
172 | extensions from a separate configuration file. | |
173 | As when reading extensions from the main configuration file, | |
174 | the '-extensions ...' option may be used for specifying the | |
175 | section to use. | |
176 | [Massimiliano Pala <madwolf@comune.modena.it>] | |
177 | ||
6308af19 DSH |
178 | *) Change PKCS12_key_gen_asc() so it can cope with non null |
179 | terminated strings whose length is passed in the passlen | |
180 | parameter, for example from PEM callbacks. This was done | |
181 | by adding an extra length parameter to asc2uni(). | |
182 | [Steve Henson, reported by <oddissey@samsung.co.kr>] | |
183 | ||
5782ceb2 DSH |
184 | *) New OCSP utility. Allows OCSP requests to be generated or |
185 | read. The request can be sent to a responder and the output | |
186 | parsed, outputed or printed in text form. Not complete yet: | |
187 | still needs to check the OCSP response validity. | |
188 | [Steve Henson] | |
189 | ||
c67cdb50 BM |
190 | *) New subcommands for 'openssl ca': |
191 | 'openssl ca -status <serial>' prints the status of the cert with | |
192 | the given serial number (according to the index file). | |
193 | 'openssl ca -updatedb' updates the expiry status of certificates | |
194 | in the index file. | |
195 | [Massimiliano Pala <madwolf@comune.modena.it>] | |
196 | ||
d199858e BM |
197 | *) New '-newreq-nodes' command option to CA.pl. This is like |
198 | '-newreq', but calls 'openssl req' with the '-nodes' option | |
199 | so that the resulting key is not encrypted. | |
200 | [Damien Miller <djm@mindrot.org>] | |
201 | ||
10a2975a RL |
202 | *) New configuration for the GNU Hurd. |
203 | [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte] | |
204 | ||
9b4dc830 DSH |
205 | *) Initial code to implement OCSP basic response verify. This |
206 | is currently incomplete. Currently just finds the signer's | |
207 | certificate and verifies the signature on the response. | |
208 | [Steve Henson] | |
209 | ||
673b3fde BM |
210 | *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in |
211 | value of OPENSSLDIR. This is available via the new '-d' option | |
212 | to 'openssl version', and is also included in 'openssl version -a'. | |
213 | [Bodo Moeller] | |
214 | ||
c06648f7 BM |
215 | *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn |
216 | call failed, free the DSA structure. | |
217 | [Bodo Moeller] | |
218 | ||
a5435e8b BM |
219 | *) Allowing defining memory allocation callbacks that will be given |
220 | file name and line number information in additional arguments | |
221 | (a const char* and an int). The basic functionality remains, as | |
222 | well as the original possibility to just replace malloc(), | |
223 | realloc() and free() by functions that do not know about these | |
224 | additional arguments. To register and find out the current | |
225 | settings for extended allocation functions, the following | |
226 | functions are provided: | |
65a22e8e RL |
227 | |
228 | CRYPTO_set_mem_ex_functions | |
229 | CRYPTO_set_locked_mem_ex_functions | |
230 | CRYPTO_get_mem_ex_functions | |
231 | CRYPTO_get_locked_mem_ex_functions | |
232 | ||
a5435e8b BM |
233 | These work the same way as CRYPTO_set_mem_functions and friends. |
234 | CRYPTO_get_[locked_]mem_functions now writes 0 where such an | |
235 | extended allocation function is enabled. | |
236 | Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where | |
237 | a conventional allocation function is enabled. | |
238 | [Richard Levitte, Bodo Moeller] | |
65a22e8e | 239 | |
cbf0f45f DSH |
240 | *) Fix to uni2asc() to cope with zero length Unicode strings. |
241 | These are present in some PKCS#12 files. | |
242 | [Steve Henson] | |
243 | ||
3c914840 GT |
244 | *) Finish off removing the remaining LHASH function pointer casts. |
245 | There should no longer be any prototype-casting required when using | |
56a67adb GT |
246 | the LHASH abstraction, and any casts that remain are "bugs". See |
247 | the callback types and macros at the head of lhash.h for details | |
248 | (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example). | |
3c914840 GT |
249 | [Geoff Thorpe] |
250 | ||
599c0353 LJ |
251 | *) Add automatic query of EGD sockets in RAND_poll() for the unix variant. |
252 | If an EGD or PRNGD is running and enough entropy is returned, automatic | |
253 | seeding like with /dev/[u]random will be performed. | |
254 | Positions tried are: /etc/entropy, /var/run/egd-pool. | |
255 | [Lutz Jaenicke] | |
256 | ||
0c61e299 | 257 | *) Change the Unix RAND_poll() variant to be able to poll several |
361ef5f4 RL |
258 | random devices, as specified by DEVRANDOM, until a sufficient amount |
259 | of data has been collected. We spend at most 10 ms on each file | |
260 | (select timeout) and read in non-blocking mode. DEVRANDOM now | |
261 | defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom" | |
262 | (previously it was just the string "/dev/urandom"), so on typical | |
263 | platforms the 10 ms delay will never occur. | |
264 | Also separate out the Unix variant to its own file, rand_unix.c. | |
265 | For VMS, there's a currently-empty rand_vms.c. | |
0c61e299 RL |
266 | [Richard Levitte] |
267 | ||
0b33bc65 DSH |
268 | *) Move OCSP client related routines to ocsp_cl.c. These |
269 | provide utility functions which an application needing | |
270 | to issue a request to an OCSP responder and analyse the | |
271 | response will typically need: as opposed to those which an | |
272 | OCSP responder itself would need which will be added later. | |
273 | ||
274 | OCSP_request_sign() signs an OCSP request with an API similar | |
275 | to PKCS7_sign(). OCSP_response_status() returns status of OCSP | |
276 | response. OCSP_response_get1_basic() extracts basic response | |
277 | from response. OCSP_resp_find_status(): finds and extracts status | |
278 | information from an OCSP_CERTID structure (which will be created | |
279 | when the request structure is built). These are built from lower | |
280 | level functions which work on OCSP_SINGLERESP structures but | |
281 | wont normally be used unless the application wishes to examine | |
282 | extensions in the OCSP response for example. | |
283 | ||
284 | Replace nonce routines with a pair of functions. | |
285 | OCSP_request_add1_nonce() adds a nonce value and optionally | |
286 | generates a random value. OCSP_check_nonce() checks the | |
287 | validity of the nonce in an OCSP response. | |
288 | [Steve Henson] | |
289 | ||
290 | *) Change function OCSP_request_add() to OCSP_request_add0_id(). | |
8e961835 DSH |
291 | This doesn't copy the supplied OCSP_CERTID and avoids the |
292 | need to free up the newly created id. Change return type | |
293 | to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure. | |
294 | This can then be used to add extensions to the request. | |
295 | Deleted OCSP_request_new(), since most of its functionality | |
296 | is now in OCSP_REQUEST_new() (and the case insensitive name | |
297 | clash) apart from the ability to set the request name which | |
298 | will be added elsewhere. | |
299 | [Steve Henson] | |
300 | ||
bf0d176e DSH |
301 | *) Update OCSP API. Remove obsolete extensions argument from |
302 | various functions. Extensions are now handled using the new | |
303 | OCSP extension code. New simple OCSP HTTP function which | |
304 | can be used to send requests and parse the response. | |
305 | [Steve Henson] | |
306 | ||
ec5add87 DSH |
307 | *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new |
308 | ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN | |
309 | uses the special reorder version of SET OF to sort the attributes | |
310 | and reorder them to match the encoded order. This resolves a long | |
311 | standing problem: a verify on a PKCS7 structure just after signing | |
312 | it used to fail because the attribute order did not match the | |
313 | encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: | |
314 | it uses the received order. This is necessary to tolerate some broken | |
315 | software that does not order SET OF. This is handled by encoding | |
316 | as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) | |
317 | to produce the required SET OF. | |
318 | [Steve Henson] | |
319 | ||
a6574c21 RL |
320 | *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and |
321 | OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header | |
322 | files to get correct declarations of the ASN.1 item variables. | |
323 | [Richard Levitte] | |
324 | ||
ecbe0781 DSH |
325 | *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many |
326 | PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: | |
327 | asn1_check_tlen() would sometimes attempt to use 'ctx' when it was | |
328 | NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). | |
329 | New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant | |
330 | ASN1_ITEM and no wrapper functions. | |
331 | [Steve Henson] | |
332 | ||
4e1209eb DSH |
333 | *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These |
334 | replace the old function pointer based I/O routines. Change most of | |
335 | the *_d2i_bio() and *_d2i_fp() functions to use these. | |
336 | [Steve Henson] | |
337 | ||
3f07fe09 RL |
338 | *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor |
339 | lines, recognice more "algorithms" that can be deselected, and make | |
340 | it complain about algorithm deselection that isn't recognised. | |
341 | [Richard Levitte] | |
342 | ||
78d3b819 | 343 | *) New ASN1 functions to handle dup, sign, verify, digest, pack and |
73e92de5 DSH |
344 | unpack operations in terms of ASN1_ITEM. Modify existing wrappers |
345 | to use new functions. Add NO_ASN1_OLD which can be set to remove | |
346 | some old style ASN1 functions: this can be used to determine if old | |
347 | code will still work when these eventually go away. | |
09ab755c DSH |
348 | [Steve Henson] |
349 | ||
ec558b65 DSH |
350 | *) New extension functions for OCSP structures, these follow the |
351 | same conventions as certificates and CRLs. | |
352 | [Steve Henson] | |
353 | ||
57d2f217 DSH |
354 | *) New function X509V3_add1_i2d(). This automatically encodes and |
355 | adds an extension. Its behaviour can be customised with various | |
356 | flags to append, replace or delete. Various wrappers added for | |
357 | certifcates and CRLs. | |
358 | [Steve Henson] | |
359 | ||
5755cab4 DSH |
360 | *) Fix to avoid calling the underlying ASN1 print routine when |
361 | an extension cannot be parsed. Correct a typo in the | |
362 | OCSP_SERVICELOC extension. Tidy up print OCSP format. | |
363 | [Steve Henson] | |
364 | ||
3880cd35 BM |
365 | *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c). |
366 | Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits | |
367 | when writing a 32767 byte record. | |
368 | [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>] | |
369 | ||
f640ee90 | 370 | *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c), |
126fe085 | 371 | obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}. |
f640ee90 BM |
372 | |
373 | (RSA objects have a reference count access to which is protected | |
374 | by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c], | |
375 | so they are meant to be shared between threads.) | |
126fe085 BM |
376 | [Bodo Moeller, Geoff Thorpe; original patch submitted by |
377 | "Reddie, Steven" <Steven.Reddie@ca.com>] | |
f640ee90 | 378 | |
9c67ab2f DSH |
379 | *) Make mkdef.pl parse some of the ASN1 macros and add apropriate |
380 | entries for variables. | |

383 | *) Fix a deadlock in CRYPTO_mem_leaks(). |
384 | [Bodo Moeller] | |
385 | ||
3ac82faa BM |
386 | *) Add functionality to apps/openssl.c for detecting locking |
387 | problems: As the program is single-threaded, all we have | |
388 | to do is register a locking callback using an array for | |
389 | storing which locks are currently held by the program. | |

390 | [Bodo Moeller] |
391 | ||
392 | *) Use a lock around the call to CRYPTO_get_ex_new_index() in | |
393 | SSL_get_ex_data_X509_STORE_idx(), which is used in | |
394 | ssl_verify_cert_chain() and thus can be called at any time | |
395 | during TLS/SSL handshakes so that thread-safety is essential. | |
396 | Unfortunately, the ex_data design is not at all suited | |
397 | for multi-threaded use, so it probably should be abolished. | |
398 | [Bodo Moeller] | |

2a86064f GT |
400 | *) Added Broadcom "ubsec" ENGINE to OpenSSL. |
401 | [Broadcom, tweaked and integrated by Geoff Thorpe] | |
402 | ||
2c15d426 DSH |
403 | *) Move common extension printing code to new function |
404 | X509V3_print_extensions(). Reorganise OCSP print routines and | |
c08523d8 | 405 | implement some needed OCSP ASN1 functions. Add OCSP extensions. |
2c15d426 DSH |
406 | [Steve Henson] |

de487514 DSH |
408 | *) New function X509_signature_print() to remove duplication in some |
409 | print routines. | |
410 | [Steve Henson] | |
411 | ||
06db4253 DSH |
412 | *) Add a special meaning when SET OF and SEQUENCE OF flags are both |
413 | set (this was treated exactly the same as SET OF previously). This | |
414 | is used to reorder the STACK representing the structure to match the | |
415 | encoding. This will be used to get round a problem where a PKCS7 | |
416 | structure which was signed could not be verified because the STACK | |
417 | order did not reflect the encoded order. | |
418 | [Steve Henson] | |
419 | ||
36f554d4 DSH |
420 | *) Reimplement the OCSP ASN1 module using the new code. |
421 | [Steve Henson] | |
422 | ||
2aff7727 DSH |
423 | *) Update the X509V3 code to permit the use of an ASN1_ITEM structure |
424 | for its ASN1 operations. The old style function pointers still exist | |
425 | for now but they will eventually go away. | |
426 | [Steve Henson] | |
427 | ||
9d6b1ce6 | 428 | *) Merge in replacement ASN1 code from the ASN1 branch. This almost |
5755cab4 DSH |
429 | completely replaces the old ASN1 functionality with a table driven |
430 | encoder and decoder which interprets an ASN1_ITEM structure describing | |
431 | the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is | |
432 | largely maintained. Almost all of the old asn1_mac.h macro based ASN1 | |
433 | has also been converted to the new form. | |
9d6b1ce6 DSH |
434 | [Steve Henson] |

8dea52fa BM |
436 | *) Change BN_mod_exp_recp so that negative moduli are tolerated |
437 | (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set | |
438 | so that BN_mod_exp_mont and BN_mod_exp_mont_word work | |
439 | for negative moduli. | |
440 | [Bodo Moeller] | |
441 | ||
442 | *) Fix BN_uadd and BN_usub: Always return non-negative results instead | |
443 | of not touching the result's sign bit. | |
444 | [Bodo Moeller] | |
445 | ||
80d89e6a BM |
446 | *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be |
447 | set. | |
448 | [Bodo Moeller] | |
449 | ||
f1919c3d GT |
450 | *) Changed the LHASH code to use prototypes for callbacks, and created |
451 | macros to declare and implement thin (optionally static) functions | |
452 | that provide type-safety and avoid function pointer casting for the | |
453 | type-specific callbacks. | |
454 | [Geoff Thorpe] | |
455 | ||
1946cd8b UM |
456 | *) Use better test patterns in bntest. |
