2 | _______________ |
3 | ||
c5e8580e | 4 | Changes between 0.9.6 and 0.9.7 [xx XXX 2000] |
a43cf9fa | 5 | |
8c950429 DSH |
6 | *) Additional options to ocsp utility to allow flags to be set and |
7 | additional certificates supplied. | |
8 | [Steve Henson] | |
9 | ||
9235adbf RL |
10 | *) Add the option -VAfile to 'openssl ocsp', so the user can give the |
11 | OCSP client a number of certificate to only verify the response | |
12 | signature against. | |
13 | [Richard Levitte] | |
14 | ||
57e7d3ce UM |
15 | *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent |
16 | Bleichenbacher's DSA attack. | |
35ed8cb8 | 17 | [Ulf Moeller, Bodo Moeller] |
57e7d3ce | 18 | |
deb2c1a1 DSH |
19 | *) Update Rijndael code to version 3.0 and change EVP AES ciphers to |
20 | handle the new API. Currently only ECB, CBC modes supported. Add new | |
21 | AES OIDs. Add TLS AES ciphersuites as described in the "AES Ciphersuites | |
22 | for TLS" draft-ietf-tls-ciphersuite-03.txt. | |
23 | [Ben Laurie, Steve Henson] | |
24 | ||
9eea2be6 BM |
25 | *) In the NCONF_...-based implementations for CONF_... queries |
26 | (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using | |
27 | a temporary CONF structure with the data component set to NULL | |
28 | (which gives segmentation faults in lh_retrieve). | |
29 | Instead, use NULL for the CONF pointer in CONF_get_string and | |
30 | CONF_get_number (which may use environment variables) and directly | |
31 | return NULL from CONF_get_section. | |
32 | [Bodo Moeller] | |
33 | ||
741a9690 UM |
34 | *) Fix potential buffer overrun for EBCDIC. |
35 | [Ulf Moeller] | |
36 | ||
26e083cc DSH |
37 | *) New function OCSP_copy_nonce() to copy nonce value (if present) from |
38 | request to response. | |
39 | [Steve Henson] | |
40 | ||
02e4fbed DSH |
41 | *) Functions for OCSP responders. OCSP_request_onereq_count(), |
42 | OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info() | |
43 | extract information from a certificate request. OCSP_response_create() | |
44 | creates a response and optionally adds a basic response structure. | |
45 | OCSP_basic_add1_status() adds a complete single response to a basic | |
46 | reponse and returns the OCSP_SINGLERESP structure just added (to allow | |
47 | extensions to be included for example). OCSP_basic_add1_cert() adds a | |
48 | certificate to a basic response and OCSP_basic_sign() signs a basic | |
49 | response with various flags. New helper functions ASN1_TIME_check() | |
50 | (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime() | |
51 | (converts ASN1_TIME to GeneralizedTime). | |
52 | [Steve Henson] | |
53 | ||
88ce56f8 DSH |
54 | *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}() |
55 | in a single operation. X509_get0_pubkey_bitstr() extracts the public_key | |
56 | structure from a certificate. X509_pubkey_digest() digests tha public_key | |
57 | contents: this is used in various key identifiers. | |
58 | [Steve Henson] | |
59 | ||
8cff6331 DSH |
60 | *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign |
61 | keyUsage if basicConstraints absent for a CA. | |
62 | [Steve Henson] | |
63 | ||
903872d6 RL |
64 | *) Make SMIME_write_PKCS7() write mail header values with a format that |
65 | is more generally accepted (no spaces before the semicolon), since | |
66 | some programs can't parse those values properly otherwise. Also make | |
67 | sure BIO's that break lines after each write do not create invalid | |
68 | headers. | |
69 | [Richard Levitte] | |
70 | ||
b8470240 DSH |
71 | *) Make sk_sort() tolerate a NULL argument. |
72 | [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>] | |
73 | ||
50d51991 DSH |
74 | *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates |
75 | passed by the function are trusted implicitly. If any of them signed the | |
76 | reponse then it is assumed to be valid and is not verified. | |
77 | [Steve Henson] | |
78 | ||
a342cc5a DSH |
79 | *) Zero the premaster secret after deriving the master secret in |
80 | DH ciphersuites. | |
81 | [Steve Henson] | |
82 | ||
a43cf9fa DSH |
83 | *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT |
84 | to data. This was previously part of the PKCS7 ASN1 code. This | |
85 | was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures. | |
86 | [Steve Henson, reported by Kenneth R. Robinette | |
87 | <support@securenetterm.com>] | |
88 | ||
89 | *) Add CRYPTO_push_info() and CRYPTO_pop_info() calls to new ASN1 | |
90 | routines: without these tracing memory leaks is very painful. | |
91 | Fix leaks in PKCS12 and PKCS7 routines. | |
92 | [Steve Henson] | |
93 | ||
75802000 UM |
94 | *) Fix for Irix with NO_ASM. |
95 | ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>] | |
96 | ||
ae0665b8 BM |
97 | *) Add some EVP_add_digest_alias registrations (as found in |
98 | OpenSSL_add_all_digests()), to SSL_library_init() | |
99 | aka OpenSSL_add_ssl_algorithms(). This provides improved | |
100 | compatibility with peers using X.509 certificates | |
101 | with unconventional AlgorithmIdentifier OIDs. | |
102 | [Bodo Moeller] | |
103 | ||
893b76c5 UM |
104 | *) ./config script fixes. |
105 | [Ulf Moeller, Richard Levitte] | |
106 | ||
ba8e2824 DSH |
107 | *) Make X509_time_adj() cope with the new behaviour of ASN1_TIME_new(). |
108 | Previously it initialised the 'type' argument to V_ASN1_UTCTIME which | |
109 | effectively meant GeneralizedTime would never be used. Now it | |
110 | is initialised to -1 but X509_time_adj() now has to check the value | |
111 | and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or | |
112 | V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime. | |
113 | [Steve Henson, reported by Kenneth R. Robinette | |
114 | <support@securenetterm.com>] | |
115 | ||
8e8972bb DSH |
116 | *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously |
117 | result in a zero length in the ASN1_INTEGER structure which was | |
118 | not consistent with the structure when d2i_ASN1_INTEGER() was used | |
119 | and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER() | |
120 | to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER() | |
121 | where it did not print out a minus for negative ASN1_INTEGER. | |
122 | [Steve Henson] | |
123 | ||
57108f0a BM |
124 | *) Fix 'openssl passwd -1'. |
125 | [Bodo Moeller] | |
126 | ||
73758d43 DSH |
127 | *) Add summary printout to ocsp utility. The various functions which |
128 | convert status values to strings have been renamed to: | |
129 | OCSP_response_status_str(), OCSP_cert_status_str() and | |
130 | OCSP_crl_reason_str() and are no longer static. New options | |
131 | to verify nonce values and to disable verification. OCSP response | |
132 | printout format cleaned up. | |
133 | [Steve Henson] | |
134 | ||
e8af92fc DSH |
135 | *) Add additional OCSP certificate checks. These are those specified |
136 | in RFC2560. This consists of two separate checks: the CA of the | |
137 | certificate being checked must either be the OCSP signer certificate | |
138 | or the issuer of the OCSP signer certificate. In the latter case the | |
139 | OCSP signer certificate must contain the OCSP signing extended key | |
140 | usage. This check is performed by attempting to match the OCSP | |
141 | signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash | |
142 | in the OCSP_CERTID structures of the response. | |
143 | [Steve Henson] | |
144 | ||
81f169e9 DSH |
145 | *) Initial OCSP certificate verification added to OCSP_basic_verify() |
146 | and related routines. This uses the standard OpenSSL certificate | |
147 | verify routines to perform initial checks (just CA validity) and | |
148 | to obtain the certificate chain. Then additional checks will be | |
149 | performed on the chain. Currently the root CA is checked to see | |
150 | if it is explicitly trusted for OCSP signing. This is used to set | |
151 | a root CA as a global signing root: that is any certificate that | |
152 | chains to that CA is an acceptable OCSP signing certificate. | |
153 | [Steve Henson] | |
154 | ||
dfebac32 BM |
155 | *) New '-extfile ...' option to 'openssl ca' for reading X.509v3 |
156 | extensions from a separate configuration file. | |
157 | As when reading extensions from the main configuration file, | |
158 | the '-extensions ...' option may be used for specifying the | |
159 | section to use. | |
160 | [Massimiliano Pala <madwolf@comune.modena.it>] | |
161 | ||
6308af19 DSH |
162 | *) Change PKCS12_key_gen_asc() so it can cope with non null |
163 | terminated strings whose length is passed in the passlen | |
164 | parameter, for example from PEM callbacks. This was done | |
165 | by adding an extra length parameter to asc2uni(). | |
166 | [Steve Henson, reported by <oddissey@samsung.co.kr>] | |
167 | ||
5782ceb2 DSH |
168 | *) New OCSP utility. Allows OCSP requests to be generated or |
169 | read. The request can be sent to a responder and the output | |
170 | parsed, outputed or printed in text form. Not complete yet: | |
171 | still needs to check the OCSP response validity. | |
172 | [Steve Henson] | |
173 | ||
c67cdb50 BM |
174 | *) New subcommands for 'openssl ca': |
175 | 'openssl ca -status <serial>' prints the status of the cert with | |
176 | the given serial number (according to the index file). | |
177 | 'openssl ca -updatedb' updates the expiry status of certificates | |
178 | in the index file. | |
179 | [Massimiliano Pala <madwolf@comune.modena.it>] | |
180 | ||
d199858e BM |
181 | *) New '-newreq-nodes' command option to CA.pl. This is like |
182 | '-newreq', but calls 'openssl req' with the '-nodes' option | |
183 | so that the resulting key is not encrypted. | |
184 | [Damien Miller <djm@mindrot.org>] | |
185 | ||
10a2975a RL |
186 | *) New configuration for the GNU Hurd. |
187 | [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte] | |
188 | ||
9b4dc830 DSH |
189 | *) Initial code to implement OCSP basic response verify. This |
190 | is currently incomplete. Currently just finds the signer's | |
191 | certificate and verifies the signature on the response. | |
192 | [Steve Henson] | |
193 | ||
673b3fde BM |
194 | *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in |
195 | value of OPENSSLDIR. This is available via the new '-d' option | |
196 | to 'openssl version', and is also included in 'openssl version -a'. | |
197 | [Bodo Moeller] | |
198 | ||
c06648f7 BM |
199 | *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn |
200 | call failed, free the DSA structure. | |
201 | [Bodo Moeller] | |
202 | ||
a5435e8b BM |
203 | *) Allowing defining memory allocation callbacks that will be given |
204 | file name and line number information in additional arguments | |
205 | (a const char* and an int). The basic functionality remains, as | |
206 | well as the original possibility to just replace malloc(), | |
207 | realloc() and free() by functions that do not know about these | |
208 | additional arguments. To register and find out the current | |
209 | settings for extended allocation functions, the following | |
210 | functions are provided: | |
65a22e8e RL |
211 | |
212 | CRYPTO_set_mem_ex_functions | |
213 | CRYPTO_set_locked_mem_ex_functions | |
214 | CRYPTO_get_mem_ex_functions | |
215 | CRYPTO_get_locked_mem_ex_functions | |
216 | ||
a5435e8b BM |
217 | These work the same way as CRYPTO_set_mem_functions and friends. |
218 | CRYPTO_get_[locked_]mem_functions now writes 0 where such an | |
219 | extended allocation function is enabled. | |
220 | Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where | |
221 | a conventional allocation function is enabled. | |
222 | [Richard Levitte, Bodo Moeller] | |
65a22e8e | 223 | |
cbf0f45f DSH |
224 | *) Fix to uni2asc() to cope with zero length Unicode strings. |
225 | These are present in some PKCS#12 files. | |
226 | [Steve Henson] | |
227 | ||
3c914840 GT |
228 | *) Finish off removing the remaining LHASH function pointer casts. |
229 | There should no longer be any prototype-casting required when using | |
56a67adb GT |
230 | the LHASH abstraction, and any casts that remain are "bugs". See |
231 | the callback types and macros at the head of lhash.h for details | |
232 | (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example). | |
3c914840 GT |
233 | [Geoff Thorpe] |
234 | ||
599c0353 LJ |
235 | *) Add automatic query of EGD sockets in RAND_poll() for the unix variant. |
236 | If an EGD or PRNGD is running and enough entropy is returned, automatic | |
237 | seeding like with /dev/[u]random will be performed. | |
238 | Positions tried are: /etc/entropy, /var/run/egd-pool. | |
239 | [Lutz Jaenicke] | |
240 | ||
0c61e299 | 241 | *) Change the Unix RAND_poll() variant to be able to poll several |
361ef5f4 RL |
242 | random devices, as specified by DEVRANDOM, until a sufficient amount |
243 | of data has been collected. We spend at most 10 ms on each file | |
244 | (select timeout) and read in non-blocking mode. DEVRANDOM now | |
245 | defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom" | |
246 | (previously it was just the string "/dev/urandom"), so on typical | |
247 | platforms the 10 ms delay will never occur. | |
248 | Also separate out the Unix variant to its own file, rand_unix.c. | |
249 | For VMS, there's a currently-empty rand_vms.c. | |
0c61e299 RL |
250 | [Richard Levitte] |
251 | ||
0b33bc65 DSH |
252 | *) Move OCSP client related routines to ocsp_cl.c. These |
253 | provide utility functions which an application needing | |
254 | to issue a request to an OCSP responder and analyse the | |
255 | response will typically need: as opposed to those which an | |
256 | OCSP responder itself would need which will be added later. | |
257 | ||
258 | OCSP_request_sign() signs an OCSP request with an API similar | |
259 | to PKCS7_sign(). OCSP_response_status() returns status of OCSP | |
260 | response. OCSP_response_get1_basic() extracts basic response | |
261 | from response. OCSP_resp_find_status(): finds and extracts status | |
262 | information from an OCSP_CERTID structure (which will be created | |
263 | when the request structure is built). These are built from lower | |
264 | level functions which work on OCSP_SINGLERESP structures but | |
265 | wont normally be used unless the application wishes to examine | |
266 | extensions in the OCSP response for example. | |
267 | ||
268 | Replace nonce routines with a pair of functions. | |
269 | OCSP_request_add1_nonce() adds a nonce value and optionally | |
270 | generates a random value. OCSP_check_nonce() checks the | |
271 | validity of the nonce in an OCSP response. | |
272 | [Steve Henson] | |
273 | ||
274 | *) Change function OCSP_request_add() to OCSP_request_add0_id(). | |
8e961835 DSH |
275 | This doesn't copy the supplied OCSP_CERTID and avoids the |
276 | need to free up the newly created id. Change return type | |
277 | to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure. | |
278 | This can then be used to add extensions to the request. | |
279 | Deleted OCSP_request_new(), since most of its functionality | |
280 | is now in OCSP_REQUEST_new() (and the case insensitive name | |
281 | clash) apart from the ability to set the request name which | |
282 | will be added elsewhere. | |
283 | [Steve Henson] | |
284 | ||
bf0d176e DSH |
285 | *) Update OCSP API. Remove obsolete extensions argument from |
286 | various functions. Extensions are now handled using the new | |
287 | OCSP extension code. New simple OCSP HTTP function which | |
288 | can be used to send requests and parse the response. | |
289 | [Steve Henson] | |
290 | ||
ec5add87 DSH |
291 | *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new |
292 | ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN | |
293 | uses the special reorder version of SET OF to sort the attributes | |
294 | and reorder them to match the encoded order. This resolves a long | |
295 | standing problem: a verify on a PKCS7 structure just after signing | |
296 | it used to fail because the attribute order did not match the | |
297 | encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: | |
298 | it uses the received order. This is necessary to tolerate some broken | |
299 | software that does not order SET OF. This is handled by encoding | |
300 | as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) | |
301 | to produce the required SET OF. | |
302 | [Steve Henson] | |
303 | ||
a6574c21 RL |
304 | *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and |
305 | OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header | |
306 | files to get correct declarations of the ASN.1 item variables. | |
307 | [Richard Levitte] | |
308 | ||
ecbe0781 DSH |
309 | *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many |
310 | PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: | |
311 | asn1_check_tlen() would sometimes attempt to use 'ctx' when it was | |
312 | NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). | |
313 | New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant | |
314 | ASN1_ITEM and no wrapper functions. | |
315 | [Steve Henson] | |
316 | ||
4e1209eb DSH |
317 | *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These |
318 | replace the old function pointer based I/O routines. Change most of | |
319 | the *_d2i_bio() and *_d2i_fp() functions to use these. | |
320 | [Steve Henson] | |
321 | ||
3f07fe09 RL |
322 | *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor |
323 | lines, recognice more "algorithms" that can be deselected, and make | |
324 | it complain about algorithm deselection that isn't recognised. | |
325 | [Richard Levitte] | |
326 | ||
78d3b819 | 327 | *) New ASN1 functions to handle dup, sign, verify, digest, pack and |
73e92de5 DSH |
328 | unpack operations in terms of ASN1_ITEM. Modify existing wrappers |
329 | to use new functions. Add NO_ASN1_OLD which can be set to remove | |
330 | some old style ASN1 functions: this can be used to determine if old | |
331 | code will still work when these eventually go away. | |
09ab755c DSH |
332 | [Steve Henson] |
333 | ||
ec558b65 DSH |
334 | *) New extension functions for OCSP structures, these follow the |
335 | same conventions as certificates and CRLs. | |
336 | [Steve Henson] | |
337 | ||
57d2f217 DSH |
338 | *) New function X509V3_add1_i2d(). This automatically encodes and |
339 | adds an extension. Its behaviour can be customised with various | |
340 | flags to append, replace or delete. Various wrappers added for | |
341 | certifcates and CRLs. | |
342 | [Steve Henson] | |
343 | ||
5755cab4 DSH |
344 | *) Fix to avoid calling the underlying ASN1 print routine when |
345 | an extension cannot be parsed. Correct a typo in the | |
346 | OCSP_SERVICELOC extension. Tidy up print OCSP format. | |
347 | [Steve Henson] | |
348 | ||
3880cd35 BM |
349 | *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c). |
350 | Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits | |
351 | when writing a 32767 byte record. | |
352 | [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>] | |
353 | ||
f640ee90 | 354 | *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c), |
126fe085 | 355 | obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}. |
f640ee90 BM |
356 | |
357 | (RSA objects have a reference count access to which is protected | |
358 | by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c], | |
359 | so they are meant to be shared between threads.) | |
126fe085 BM |
360 | [Bodo Moeller, Geoff Thorpe; original patch submitted by |
361 | "Reddie, Steven" <Steven.Reddie@ca.com>] | |
f640ee90 | 362 | |
9c67ab2f DSH |
363 | *) Make mkdef.pl parse some of the ASN1 macros and add apropriate |
364 | entries for variables. | |
5755cab4 | 365 | [Steve Henson] |
9c67ab2f | 366 | |
1456d186 BM |
367 | *) Fix a deadlock in CRYPTO_mem_leaks(). |
368 | [Bodo Moeller] | |
369 | ||
3ac82faa BM |
370 | *) Add functionality to apps/openssl.c for detecting locking |
371 | problems: As the program is single-threaded, all we have | |
372 | to do is register a locking callback using an array for | |
373 | storing which locks are currently held by the program. | |
3ac82faa BM |
374 | [Bodo Moeller] |
375 | ||
376 | *) Use a lock around the call to CRYPTO_get_ex_new_index() in | |
377 | SSL_get_ex_data_X509_STORE_idx(), which is used in | |
378 | ssl_verify_cert_chain() and thus can be called at any time | |
379 | during TLS/SSL handshakes so that thread-safety is essential. | |
380 | Unfortunately, the ex_data design is not at all suited | |
381 | for multi-threaded use, so it probably should be abolished. | |
382 | [Bodo Moeller] | |

2a86064f GT |
384 | *) Added Broadcom "ubsec" ENGINE to OpenSSL. |
385 | [Broadcom, tweaked and integrated by Geoff Thorpe] | |

2c15d426 DSH |
387 | *) Move common extension printing code to new function |
388 | X509V3_print_extensions(). Reorganise OCSP print routines and | |
c08523d8 | 389 | implement some needed OCSP ASN1 functions. Add OCSP extensions. |

de487514 DSH |
392 | *) New function X509_signature_print() to remove duplication in some |
393 | print routines. | |
394 | [Steve Henson] | |
395 | ||
06db4253 DSH |
396 | *) Add a special meaning when SET OF and SEQUENCE OF flags are both |
397 | set (this was treated exactly the same as SET OF previously). This | |
398 | is used to reorder the STACK representing the structure to match the | |
399 | encoding. This will be used to get round a problem where a PKCS7 | |
400 | structure which was signed could not be verified because the STACK | |
401 | order did not reflect the encoded order. | |
402 | [Steve Henson] | |
403 | ||
36f554d4 DSH |
404 | *) Reimplement the OCSP ASN1 module using the new code. |
405 | [Steve Henson] | |
406 | ||
2aff7727 DSH |
407 | *) Update the X509V3 code to permit the use of an ASN1_ITEM structure |
408 | for its ASN1 operations. The old style function pointers still exist | |
409 | for now but they will eventually go away. | |
410 | [Steve Henson] | |
411 | ||
9d6b1ce6 | 412 | *) Merge in replacement ASN1 code from the ASN1 branch. This almost |
5755cab4 DSH |
413 | completely replaces the old ASN1 functionality with a table driven |
414 | encoder and decoder which interprets an ASN1_ITEM structure describing | |
415 | the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is | |
416 | largely maintained. Almost all of the old asn1_mac.h macro based ASN1 | |
417 | has also been converted to the new form. | |
9d6b1ce6 DSH |

8dea52fa BM |
420 | *) Change BN_mod_exp_recp so that negative moduli are tolerated |
421 | (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set | |
422 | so that BN_mod_exp_mont and BN_mod_exp_mont_word work | |
423 | for negative moduli. | |
424 | [Bodo Moeller] | |
425 | ||
426 | *) Fix BN_uadd and BN_usub: Always return non-negative results instead | |
427 | of not touching the result's sign bit. | |
428 | [Bodo Moeller] | |
429 | ||
80d89e6a BM |
430 | *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be |
431 | set. | |
432 | [Bodo Moeller] | |
433 | ||
f1919c3d GT |
434 | *) Changed the LHASH code to use prototypes for callbacks, and created |
435 | macros to declare and implement thin (optionally static) functions | |
436 | that provide type-safety and avoid function pointer casting for the | |
437 | type-specific callbacks. | |
438 | [Geoff Thorpe] | |
439 | ||
1946cd8b UM |
440 | *) Use better test patterns in bntest. |
