3 | _______________ |
4 | ||
7d3ba88a | 5 | Changes between 1.0.2 and 1.1.0 [xx XXX xxxx] |
6668b6b8 | 6 | |
995101d6 RS |
7 | *) Added HTTP GET support to the ocsp command. |
8 | [Rich Salz] | |
9 | ||
302d38e3 MC |
10 | *) RAND_pseudo_bytes has been deprecated. Users should use RAND bytes instead. |
11 | ||
6668b6b8 DSH |
12 | *) Added support for TLS extended master secret from |
13 | draft-ietf-tls-session-hash-03.txt. Thanks for Alfredo Pironti for an | |
14 | initial patch which was a great help during development. | |
15 | [Steve Henson] | |
16 | ||
78cc1f03 MC |
17 | *) All libssl internal structures have been removed from the public header |
18 | files, and the OPENSSL_NO_SSL_INTERN option has been removed (since it is | |
19 | now redundant). Users should not attempt to access internal structures | |
20 | directly. Instead they should use the provided API functions. | |
21 | [Matt Caswell] | |
785da0e6 | 22 | |
bd2bd374 MC |
23 | *) config has been changed so that by default OPENSSL_NO_DEPRECATED is used. |
24 | Access to deprecated functions can be re-enabled by running config with | |
25 | "enable-deprecated". In addition applications wishing to use deprecated | |
26 | functions must define OPENSSL_USE_DEPRECATED. Note that this new behaviour | |
27 | will, by default, disable some transitive includes that previously existed | |
28 | in the header files (e.g. ec.h will no longer, by default, include bn.h) | |
29 | [Matt Caswell] | |
30 | ||
0c1bd7f0 MC |
31 | *) Added support for OCB mode. OpenSSL has been granted a patent license |
32 | compatible with the OpenSSL license for use of OCB. Details are available | |
33 | at https://www.openssl.org/docs/misc/OCB-patent-grant-OpenSSL.pdf. Support | |
34 | for OCB can be removed by calling config with no-ocb. | |
bd2bd374 | 35 | [Matt Caswell] |
0c1bd7f0 | 36 | |
12478cc4 KR |
37 | *) SSLv2 support has been removed. It still supports receiving a SSLv2 |
38 | compatible client hello. | |
39 | [Kurt Roeckx] | |
40 | ||
c56a50b2 AY |
41 | *) Increased the minimal RSA keysize from 256 to 512 bits [Rich Salz], |
42 | done while fixing the error code for the key-too-small case. | |
43 | [Annie Yousar <a.yousar@informatik.hu-berlin.de>] | |
44 | ||
be739b0c RS |
45 | *) CA.sh has been removmed; use CA.pl instead. |
46 | [Rich Salz] | |
47 | ||
24956ca0 RS |
48 | *) Removed old DES API. |
49 | [Rich Salz] | |
50 | ||

62 | 16-bit platforms such as WIN16 | |
b317819b RS |
63 | [Rich Salz] |
64 | ||
10bf4fc2 RS |
65 | *) Clean up OPENSSL_NO_xxx #define's |
66 | Use setbuf() and remove OPENSSL_NO_SETVBUF_IONBF | |
68b00c23 | 67 | Rename OPENSSL_SYSNAME_xxx to OPENSSL_SYS_xxx |
10bf4fc2 RS |
68 | OPENSSL_NO_EC{DH,DSA} merged into OPENSSL_NO_EC |
69 | OPENSSL_NO_RIPEMD160, OPENSSL_NO_RIPEMD merged into OPENSSL_NO_RMD160 | |
70 | OPENSSL_NO_FP_API merged into OPENSSL_NO_STDIO | |
71 | Remove OPENSSL_NO_BIO OPENSSL_NO_BUFFER OPENSSL_NO_CHAIN_VERIFY | |
72 | OPENSSL_NO_EVP OPENSSL_NO_FIPS_ERR OPENSSL_NO_HASH_COMP | |
73 | OPENSSL_NO_LHASH OPENSSL_NO_OBJECT OPENSSL_NO_SPEED OPENSSL_NO_STACK | |
74 | OPENSSL_NO_X509 OPENSSL_NO_X509_VERIFY | |
68b00c23 | 75 | Remove MS_STATIC; it's a relic from platforms <32 bits. |
4b618848 RS |
76 | [Rich Salz] |
77 | ||
10bf4fc2 | 78 | *) Cleaned up dead code |
a2b18e65 RS |
79 | Remove all but one '#ifdef undef' which is to be looked at. |
80 | [Rich Salz] | |
81 | ||
0dfb9398 RS |
82 | *) Clean up calling of xxx_free routines. |
83 | Just like free(), fix most of the xxx_free routines to accept | |
84 | NULL. Remove the non-null checks from callers. Save much code. | |
85 | [Rich Salz] | |
86 | ||
5fc3a5fe BL |
87 | *) Experimental support for a new, fast, unbiased prime candidate generator, |
88 | bn_probable_prime_dh_coprime(). Not currently used by any prime generator. | |
89 | [Felix Laurie von Massenbach <felix@erbridge.co.uk>] | |
90 | ||
189ae368 MK |
91 | *) New output format NSS in the sess_id command line tool. This allows |
92 | exporting the session id and the master key in NSS keylog format. | |
93 | [Martin Kaiser <martin@kaiser.cx>] | |
94 | ||
8acb9538 | 95 | *) Harmonize version and its documentation. -f flag is used to display |
96 | compilation flags. | |
97 | [mancha <mancha1@zoho.com>] | |
98 | ||
e14f14d3 | 99 | *) Fix eckey_priv_encode so it immediately returns an error upon a failure |
100 | in i2d_ECPrivateKey. | |
101 | [mancha <mancha1@zoho.com>] | |
102 | ||
4ba5e63b BL |
103 | *) Fix some double frees. These are not thought to be exploitable. |
104 | [mancha <mancha1@zoho.com>] | |
105 | ||
731f4314 DSH |
106 | *) A missing bounds check in the handling of the TLS heartbeat extension |
107 | can be used to reveal up to 64k of memory to a connected client or | |
108 | server. | |
109 | ||
110 | Thanks for Neel Mehta of Google Security for discovering this bug and to | |
111 | Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for | |
112 | preparing the fix (CVE-2014-0160) | |
113 | [Adam Langley, Bodo Moeller] | |
114 | ||
f9b6c0ba DSH |
115 | *) Fix for the attack described in the paper "Recovering OpenSSL |
116 | ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack" | |
117 | by Yuval Yarom and Naomi Benger. Details can be obtained from: | |
118 | http://eprint.iacr.org/2014/140 | |
119 | ||
120 | Thanks to Yuval Yarom and Naomi Benger for discovering this | |
121 | flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076) | |
122 | [Yuval Yarom and Naomi Benger] | |
123 | ||
a4339ea3 | 124 | *) Use algorithm specific chains in SSL_CTX_use_certificate_chain_file(): |
14e96192 | 125 | this fixes a limitation in previous versions of OpenSSL. |
a4339ea3 DSH |
126 | [Steve Henson] |
127 | ||
5e3ff62c DSH |
128 | *) Experimental encrypt-then-mac support. |
129 | ||
130 | Experimental support for encrypt then mac from | |
131 | draft-gutmann-tls-encrypt-then-mac-02.txt | |
a6e7d1c0 | 132 | |
5fdeb58c DSH |
133 | To enable it set the appropriate extension number (0x42 for the test |
134 | server) using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x42 | |
a6e7d1c0 | 135 | |
5e3ff62c DSH |
136 | For non-compliant peers (i.e. just about everything) this should have no |
137 | effect. | |
138 | ||
139 | WARNING: EXPERIMENTAL, SUBJECT TO CHANGE. | |
a6e7d1c0 | 140 | |
5e3ff62c DSH |
141 | [Steve Henson] |
142 | ||
97cf1f6c DSH |
143 | *) Add EVP support for key wrapping algorithms, to avoid problems with |
144 | existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in | |
145 | the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap | |
146 | algorithms and include tests cases. | |
147 | [Steve Henson] | |
148 | ||
5c84d2f5 DSH |
149 | *) Extend CMS code to support RSA-PSS signatures and RSA-OAEP for |
150 | enveloped data. | |
151 | [Steve Henson] | |
152 | ||
271fef0e DSH |
153 | *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest, |
154 | MGF1 digest and OAEP label. | |
155 | [Steve Henson] | |
156 | ||
fefc111a BL |
157 | *) Make openssl verify return errors. |
158 | [Chris Palmer <palmer@google.com> and Ben Laurie] | |
159 | ||
1c455bc0 DSH |
160 | *) New function ASN1_TIME_diff to calculate the difference between two |
161 | ASN1_TIME structures or one structure and the current time. | |
162 | [Steve Henson] | |
163 | ||
a98b8ce6 DSH |
164 | *) Update fips_test_suite to support multiple command line options. New |
165 | test to induce all self test errors in sequence and check expected | |
166 | failures. | |
167 | [Steve Henson] | |
168 | ||
f4324e51 DSH |
169 | *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and |
170 | sign or verify all in one operation. | |
171 | [Steve Henson] | |
172 | ||
14e96192 | 173 | *) Add fips_algvs: a multicall fips utility incorporating all the algorithm |
3ec9dceb DSH |
174 | test programs and fips_test_suite. Includes functionality to parse |
175 | the minimal script output of fipsalgest.pl directly. | |
f4324e51 | 176 | [Steve Henson] |
3ec9dceb | 177 | |
5e4eb995 DSH |
178 | *) Add authorisation parameter to FIPS_module_mode_set(). |
179 | [Steve Henson] | |
180 | ||
2bfeb7dc DSH |
181 | *) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves. |
182 | [Steve Henson] | |
183 | ||
4420b3b1 | 184 | *) Use separate DRBG fields for internal and external flags. New function |
cb71870d DSH |
185 | FIPS_drbg_health_check() to perform on demand health checking. Add |
186 | generation tests to fips_test_suite with reduced health check interval to | |
4420b3b1 DSH |
187 | demonstrate periodic health checking. Add "nodh" option to |
188 | fips_test_suite to skip very slow DH test. | |
189 | [Steve Henson] | |
190 | ||
15094852 DSH |
191 | *) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers |
192 | based on NID. | |
193 | [Steve Henson] | |
194 | ||
a11f06b2 DSH |
195 | *) More extensive health check for DRBG checking many more failure modes. |
196 | New function FIPS_selftest_drbg_all() to handle every possible DRBG | |
197 | combination: call this in fips_test_suite. | |
198 | [Steve Henson] | |
199 | ||
7fdcb457 DSH |
200 | *) Add support for Dual EC DRBG from SP800-90. Update DRBG algorithm test |
201 | and POST to handle Dual EC cases. | |
202 | [Steve Henson] | |
203 | ||
f55f5f77 DSH |
204 | *) Add support for canonical generation of DSA parameter 'g'. See |
205 | FIPS 186-3 A.2.3. | |
206 | ||
7fdcb457 DSH |
207 | *) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and |
208 | POST to handle HMAC cases. | |
20f12e63 DSH |
209 | [Steve Henson] |
210 | ||
01a9a759 | 211 | *) Add functions FIPS_module_version() and FIPS_module_version_text() |
3d7bf77f | 212 | to return numerical and string versions of the FIPS module number. |
01a9a759 DSH |
213 | [Steve Henson] |
214 | ||
c2fd5989 | 215 | *) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and |
3d7bf77f | 216 | FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implemented |
c2fd5989 DSH |
217 | outside the validated module in the FIPS capable OpenSSL. |
218 | [Steve Henson] | |
219 | ||
e0d1a2f8 | 220 | *) Minor change to DRBG entropy callback semantics. In some cases |
3d7bf77f | 221 | there is no multiple of the block length between min_len and |
e0d1a2f8 DSH |
222 | max_len. Allow the callback to return more than max_len bytes |
223 | of entropy but discard any extra: it is the callback's responsibility | |
224 | to ensure that the extra data discarded does not impact the | |
225 | requested amount of entropy. | |
226 | [Steve Henson] | |
227 | ||
cac4fb58 DSH |
228 | *) Add PRNG security strength checks to RSA, DSA and ECDSA using |
229 | information in FIPS186-3, SP800-57 and SP800-131A. | |
230 | [Steve Henson] | |
231 | ||
b5dd1787 DSH |
232 | *) CCM support via EVP. Interface is very similar to GCM case except we |
233 | must supply all data in one chunk (i.e. no update, final) and the | |
234 | message length must be supplied if AAD is used. Add algorithm test | |
235 | support. | |
23916810 DSH |
236 | [Steve Henson] |
237 | ||
ac892b7a DSH |
238 | *) Initial version of POST overhaul. Add POST callback to allow the status |
239 | of POST to be monitored and/or failures induced. Modify fips_test_suite | |
240 | to use callback. Always run all selftests even if one fails. | |
241 | [Steve Henson] | |
242 | ||
06b7e5a0 DSH |
243 | *) XTS support including algorithm test driver in the fips_gcmtest program. |
244 | Note: this does increase the maximum key length from 32 to 64 bytes but | |
245 | there should be no binary compatibility issues as existing applications | |
246 | will never use XTS mode. | |
32a2d8dd DSH |
247 | [Steve Henson] |
248 | ||
05e24c87 DSH |
249 | *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies |
250 | to OpenSSL RAND code and replace with a tiny FIPS RAND API which also | |
251 | performs algorithm blocking for unapproved PRNG types. Also do not | |
252 | set PRNG type in FIPS_mode_set(): leave this to the application. | |
253 | Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with | |
d7a3ce98 | 254 | the standard OpenSSL PRNG: set additional data to a date time vector. |
05e24c87 DSH |
255 | [Steve Henson] |
256 | ||
cab0595c DSH |
257 | *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*. |
258 | This shouldn't present any incompatibility problems because applications | |
259 | shouldn't be using these directly and any that are will need to rethink | |
260 | anyway as the X9.31 PRNG is now deprecated by FIPS 140-2 | |
261 | [Steve Henson] | |
262 | ||
96ec46f7 DSH |
263 | *) Extensive self tests and health checking required by SP800-90 DRBG. |
264 | Remove strength parameter from FIPS_drbg_instantiate and always | |
265 | instantiate at maximum supported strength. | |
266 | [Steve Henson] | |
267 | ||
8857b380 DSH |
268 | *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing. |
269 | [Steve Henson] | |
270 | ||
11e80de3 DSH |
271 | *) New algorithm test program fips_dhvs to handle DH primitives only testing. |
272 | [Steve Henson] | |
273 | ||
274 | *) New function DH_compute_key_padded() to compute a DH key and pad with | |
275 | leading zeroes if needed: this complies with SP800-56A et al. | |
276 | [Steve Henson] | |
277 | ||
591cbfae DSH |
278 | *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by |
279 | anything, incomplete, subject to change and largely untested at present. | |
280 | [Steve Henson] | |
281 | ||
eead69f5 DSH |
282 | *) Modify fipscanisteronly build option to only build the necessary object |
283 | files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile. | |
284 | [Steve Henson] | |
285 | ||
017bc57b DSH |
286 | *) Add experimental option FIPSSYMS to give all symbols in |
287 | fipscanister.o and FIPS or fips prefix. This will avoid | |
5d439d69 DSH |
288 | conflicts with future versions of OpenSSL. Add perl script |
289 | util/fipsas.pl to preprocess assembly language source files | |
290 | and rename any affected symbols. | |
017bc57b DSH |
291 | [Steve Henson] |
292 | ||
25c65429 DSH |
293 | *) Add selftest checks and algorithm block of non-fips algorithms in |
294 | FIPS mode. Remove DES2 from selftests. | |
295 | [Steve Henson] | |
296 | ||
fe26d066 DSH |
297 | *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just |
298 | return internal method without any ENGINE dependencies. Add new | |
25c65429 | 299 | tiny fips sign and verify functions. |
fe26d066 DSH |
300 | [Steve Henson] |
301 | ||
b3310161 DSH |
302 | *) New build option no-ec2m to disable characteristic 2 code. |
303 | [Steve Henson] | |
304 | ||
30b56225 DSH |
305 | *) New build option "fipscanisteronly". This only builds fipscanister.o |
306 | and (currently) associated fips utilities. Uses the file Makefile.fips | |
307 | instead of Makefile.org as the prototype. | |
308 | [Steve Henson] | |
309 | ||
b3d8022e DSH |
310 | *) Add some FIPS mode restrictions to GCM. Add internal IV generator. |
311 | Update fips_gcmtest to use IV generator. | |
312 | [Steve Henson] | |
313 | ||
bdaa5415 DSH |
314 | *) Initial, experimental EVP support for AES-GCM. AAD can be input by |
315 | setting output buffer to NULL. The *Final function must be | |
316 | called although it will not retrieve any additional data. The tag | |
317 | can be set or retrieved with a ctrl. The IV length is by default 12 | |
318 | bytes (96 bits) but can be set to an alternative value. If the IV | |
319 | length exceeds the maximum IV length (currently 16 bytes) it cannot be | |
320 | set before the key. | |
321 | [Steve Henson] | |
322 | ||
3da0ca79 DSH |
323 | *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the |
324 | underlying do_cipher function handles all cipher semantics itself | |
325 | including padding and finalisation. This is useful if (for example) | |
326 | an ENGINE cipher handles block padding itself. The behaviour of | |
327 | do_cipher is subtly changed if this flag is set: the return value | |
328 | is the number of characters written to the output buffer (zero is | |
329 | no longer an error code) or a negative error code. Also if the | |
d45087c6 | 330 | input buffer is NULL and length 0 finalisation should be performed. |
3da0ca79 DSH |
331 | [Steve Henson] |
332 | ||
2b3936e8 DSH |
333 | *) If a candidate issuer certificate is already part of the constructed |
334 | path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case. | |
335 | [Steve Henson] | |
336 | ||
7c2d4fee BM |
337 | *) Improve forward-security support: add functions |
338 | ||
339 | void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure)) | |
340 | void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure)) | |
341 | ||
342 | for use by SSL/TLS servers; the callback function will be called whenever a | |
343 | new session is created, and gets to decide whether the session may be | |
344 | cached to make it resumable (return 0) or not (return 1). (As by the | |
345 | SSL/TLS protocol specifications, the session_id sent by the server will be | |
346 | empty to indicate that the session is not resumable; also, the server will | |
347 | not generate RFC 4507 (RFC 5077) session tickets.) | |
348 | ||
349 | A simple reasonable callback implementation is to return is_forward_secure. | |
350 | This parameter will be set to 1 or 0 depending on the ciphersuite selected | |
351 | by the SSL/TLS server library, indicating whether it can provide forward | |
352 | security. | |
353 |
