0f32c841 | 5 | Changes between 0.9.8f and 0.9.9 [xx XXX xxxx] |
3ff55e96 | 6 | |
47b71e6e DSH |
7 | *) Experimental support for use of HMAC via EVP_PKEY interface. This |
8 | allows HMAC to be handled via the EVP_DigestSign*() interface. The | |
9 | EVP_PKEY "key" in this case is the HMAC key, potentially allowing | |
10 | ENGINE support for HMAC keys which are unextractable. | |
11 | [Steve Henson] | |
12 | ||
d952c79a DSH |
13 | *) New option -sigopt to dgst utility. Update dgst to use |
14 | EVP_Digest{Sign,Verify}*. These two changes make it possible to use | |
15 | alternative signing paramaters such as X9.31 or PSS in the dgst | |
16 | utility. | |
17 | [Steve Henson] | |
18 | ||
fd5bc65c BM |
19 | *) Change ssl_cipher_apply_rule(), the internal function that does |
20 | the work each time a ciphersuite string requests enabling | |
21 | ("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or | |
22 | removing ("!foo+bar") a class of ciphersuites: Now it maintains | |
23 | the order of disabled ciphersuites such that those ciphersuites | |
24 | that most recently went from enabled to disabled not only stay | |
25 | in order with respect to each other, but also have higher priority | |
26 | than other disabled ciphersuites the next time ciphersuites are | |
27 | enabled again. | |
28 | ||
29 | This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable | |
30 | the same ciphersuites as with "HIGH" alone, but in a specific | |
31 | order where the PSK ciphersuites come first (since they are the | |
32 | most recently disabled ciphersuites when "HIGH" is parsed). | |
33 | ||
34 | Also, change ssl_create_cipher_list() (using this new | |
35 | funcionality) such that between otherwise identical | |
36 | cihpersuites, ephemeral ECDH is preferred over ephemeral DH in | |
37 | the default order. | |
38 | [Bodo Moeller] | |
39 | ||
0a05123a BM |
40 | *) Change ssl_create_cipher_list() so that it automatically |
41 | arranges the ciphersuites in reasonable order before starting | |
42 | to process the rule string. Thus, the definition for "DEFAULT" | |
43 | (SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but | |
44 | remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH". | |
45 | This makes it much easier to arrive at a reasonable default order | |
46 | in applications for which anonymous ciphers are OK (meaning | |
47 | that you can't actually use DEFAULT). | |
48 | [Bodo Moeller; suggested by Victor Duchovni] | |
49 | ||
52b8dad8 BM |
50 | *) Split the SSL/TLS algorithm mask (as used for ciphersuite string |
51 | processing) into multiple integers instead of setting | |
52 | "SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK", | |
53 | "SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer. | |
54 | (These masks as well as the individual bit definitions are hidden | |
55 | away into the non-exported interface ssl/ssl_locl.h, so this | |
56 | change to the definition of the SSL_CIPHER structure shouldn't | |
57 | affect applications.) This give us more bits for each of these | |
58 | categories, so there is no longer a need to coagulate AES128 and | |
59 | AES256 into a single algorithm bit, and to coagulate Camellia128 | |
60 | and Camellia256 into a single algorithm bit, which has led to all | |
61 | kinds of kludges. | |
62 | ||
63 | Thus, among other things, the kludge introduced in 0.9.7m and | |
64 | 0.9.8e for masking out AES256 independently of AES128 or masking | |
65 | out Camellia256 independently of AES256 is not needed here in 0.9.9. | |
66 | ||
67 | With the change, we also introduce new ciphersuite aliases that | |
68 | so far were missing: "AES128", "AES256", "CAMELLIA128", and | |
69 | "CAMELLIA256". | |
70 | [Bodo Moeller] | |
71 | ||
357d5de5 NL |
72 | *) Add support for dsa-with-SHA224 and dsa-with-SHA256. |
73 | Use the leftmost N bytes of the signature input if the input is | |
74 | larger than the prime q (with N being the size in bytes of q). | |
75 | [Nils Larsch] | |
76 | ||
11d8cdc6 DSH |
77 | *) Very *very* experimental PKCS#7 streaming encoder support. Nothing uses |
78 | it yet and it is largely untested. | |
79 | [Steve Henson] | |
80 | ||
06e2dd03 NL |
81 | *) Add support for the ecdsa-with-SHA224/256/384/512 signature types. |
82 | [Nils Larsch] | |
83 | ||
de121164 DSH |
84 | *) Initial incomplete changes to avoid need for function casts in OpenSSL |
85 | when OPENSSL_NO_FCAST is set: some compilers (gcc 4.2 and later) reject | |
86 | their use. Safestack is reimplemented using inline functions: tests show | |
87 | that these calls are typically optimized away by compilers so they have | |
88 | no additional overhead. Update ASN1 to avoid use of legacy functions. | |
89 | [Steve Henson] | |
90 | ||
3189772e AP |
91 | *) Win32/64 targets are linked with Winsock2. |
92 | [Andy Polyakov] | |
93 | ||
010fa0b3 DSH |
94 | *) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected |
95 | to external functions. This can be used to increase CRL handling | |
96 | efficiency especially when CRLs are very large by (for example) storing | |
97 | the CRL revoked certificates in a database. | |
98 | [Steve Henson] | |
99 | ||
5d20c4fb DSH |
100 | *) Overhaul of by_dir code. Add support for dynamic loading of CRLs so |
101 | new CRLs added to a directory can be used. New command line option | |
102 | -verify_return_error to s_client and s_server. This causes real errors | |
103 | to be returned by the verify callback instead of carrying on no matter | |
104 | what. This reflects the way a "real world" verify callback would behave. | |
105 | [Steve Henson] | |
106 | ||
107 | *) GOST engine, supporting several GOST algorithms and public key formats. | |
108 | Kindly donated by Cryptocom. | |
109 | [Cryptocom] | |
110 | ||
bc7535bc DSH |
111 | *) Partial support for Issuing Distribution Point CRL extension. CRLs |
112 | partitioned by DP are handled but no indirect CRL or reason partitioning | |
113 | (yet). Complete overhaul of CRL handling: now the most suitable CRL is | |
114 | selected via a scoring technique which handles IDP and AKID in CRLs. | |
115 | [Steve Henson] | |
116 | ||
117 | *) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which | |
118 | will ultimately be used for all verify operations: this will remove the | |
119 | X509_STORE dependency on certificate verification and allow alternative | |
120 | lookup methods. X509_STORE based implementations of these two callbacks. | |
121 | [Steve Henson] | |
122 | ||
f6e7d014 DSH |
123 | *) Allow multiple CRLs to exist in an X509_STORE with matching issuer names. |
124 | Modify get_crl() to find a valid (unexpired) CRL if possible. | |
125 | [Steve Henson] | |
126 | ||
edc54021 DSH |
127 | *) New function X509_CRL_match() to check if two CRLs are identical. Normally |
128 | this would be called X509_CRL_cmp() but that name is already used by | |
129 | a function that just compares CRL issuer names. Cache several CRL | |
130 | extensions in X509_CRL structure and cache CRLDP in X509. | |
131 | [Steve Henson] | |
132 | ||
450ea834 DSH |
133 | *) Store a "canonical" representation of X509_NAME structure (ASN1 Name) |
134 | this maps equivalent X509_NAME structures into a consistent structure. | |
135 | Name comparison can then be performed rapidly using memcmp(). | |
136 | [Steve Henson] | |
137 | ||
454dbbc5 DSH |
138 | *) Non-blocking OCSP request processing. Add -timeout option to ocsp |
139 | utility. | |
c1c6c0bf DSH |
140 | [Steve Henson] |
141 | ||
b7683e3a DSH |
142 | *) Allow digests to supply their own micalg string for S/MIME type using |
143 | the ctrl EVP_MD_CTRL_MICALG. | |
144 | [Steve Henson] | |
145 | ||
146 | *) During PKCS7 signing pass the PKCS7 SignerInfo structure to the | |
147 | EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN | |
148 | ctrl. It can then customise the structure before and/or after signing | |
149 | if necessary. | |
150 | [Steve Henson] | |
151 | ||
0ee2166c DSH |
152 | *) New function OBJ_add_sigid() to allow application defined signature OIDs |
153 | to be added to OpenSSLs internal tables. New function OBJ_sigid_free() | |
154 | to free up any added signature OIDs. | |
155 | [Steve Henson] | |
156 | ||
5ba4bf35 DSH |
157 | *) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(), |
158 | EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal | |
159 | digest and cipher tables. New options added to openssl utility: | |
160 | list-message-digest-algorithms and list-cipher-algorithms. | |
161 | [Steve Henson] | |
162 | ||
48fc582f BM |
163 | *) In addition to the numerical (unsigned long) thread ID, provide |
164 | for a pointer (void *) thread ID. This helps accomodate systems | |
165 | that do not provide an unsigned long thread ID. OpenSSL assumes | |
166 | it is in the same thread iff both the numerical and the pointer | |
167 | thread ID agree; so applications are just required to define one | |
168 | of them appropriately (e.g., by using a pointer to a per-thread | |
169 | memory object malloc()ed by the application for the pointer-type | |
170 | thread ID). Exactly analoguous to the existing functions | |
171 | ||
172 | void CRYPTO_set_id_callback(unsigned long (*func)(void)); | |
173 | unsigned long (*CRYPTO_get_id_callback(void))(void); | |
174 | unsigned long CRYPTO_thread_id(void); | |
175 | ||
176 | we now have additional functions | |
177 | ||
178 | void CRYPTO_set_idptr_callback(void *(*func)(void)); | |
179 | void *(*CRYPTO_get_idptr_callback(void))(void); | |
180 | void *CRYPTO_thread_idptr(void); | |
181 | ||
182 | also in <openssl/crypto.h>. The default value for | |
183 | CRYPTO_thread_idptr() if the application has not provided its own | |
184 | callback is &errno. | |
185 | [Bodo Moeller] | |
186 | ||
c4e7870a BM |
187 | *) Change the array representation of binary polynomials: the list |
188 | of degrees of non-zero coefficients is now terminated with -1. | |
189 | Previously it was terminated with 0, which was also part of the | |
190 | value; thus, the array representation was not applicable to | |
191 | polynomials where t^0 has coefficient zero. This change makes | |
192 | the array representation useful in a more general context. | |
193 | [Douglas Stebila] | |
194 | ||
89bbe14c BM |
195 | *) Various modifications and fixes to SSL/TLS cipher string |
196 | handling. For ECC, the code now distinguishes between fixed ECDH | |
197 | with RSA certificates on the one hand and with ECDSA certificates | |
198 | on the other hand, since these are separate ciphersuites. The | |
199 | unused code for Fortezza ciphersuites has been removed. | |
200 | ||
201 | For consistency with EDH, ephemeral ECDH is now called "EECDH" | |
202 | (not "ECDHE"). For consistency with the code for DH | |
203 | certificates, use of ECDH certificates is now considered ECDH | |
204 | authentication, not RSA or ECDSA authentication (the latter is | |
205 | merely the CA's signing algorithm and not actively used in the | |
206 | protocol). | |
207 | ||
208 | The temporary ciphersuite alias "ECCdraft" is no longer | |
209 | available, and ECC ciphersuites are no longer excluded from "ALL" | |
210 | and "DEFAULT". The following aliases now exist for RFC 4492 | |
211 | ciphersuites, most of these by analogy with the DH case: | |
212 | ||
213 | kECDHr - ECDH cert, signed with RSA | |
214 | kECDHe - ECDH cert, signed with ECDSA | |
215 | kECDH - ECDH cert (signed with either RSA or ECDSA) | |
216 | kEECDH - ephemeral ECDH | |
217 | ECDH - ECDH cert or ephemeral ECDH | |
218 | ||
219 | aECDH - ECDH cert | |
220 | aECDSA - ECDSA cert | |
221 | ECDSA - ECDSA cert | |
222 | ||
223 | AECDH - anonymous ECDH | |
224 | EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH") | |
225 | ||
226 | [Bodo Moeller] | |
227 | ||
fb7b3932 DSH |
228 | *) Add additional S/MIME capabilities for AES and GOST ciphers if supported. |
229 | Use correct micalg parameters depending on digest(s) in signed message. | |
230 | [Steve Henson] | |
231 | ||
01b8b3c7 DSH |
232 | *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process |
233 | an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code. | |
234 | [Steve Henson] | |
de9fcfe3 | 235 | |
58aa573a | 236 | *) Initial engine support for EVP_PKEY_METHOD. New functions to permit |
c9777d26 DSH |
237 | an engine to register a method. Add ENGINE lookups for methods and |
238 | functional reference processing. | |
58aa573a DSH |
239 | [Steve Henson] |
240 | ||
91c9e621 DSH |
241 | *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of |
242 | EVP_{Sign,Verify}* which allow an application to customise the signature | |
243 | process. | |
244 | [Steve Henson] | |
245 | ||
55311921 DSH |
246 | *) New -resign option to smime utility. This adds one or more signers |
247 | to an existing PKCS#7 signedData structure. Also -md option to use an | |
248 | alternative message digest algorithm for signing. | |
249 | [Steve Henson] | |
250 | ||
a6e7fcd1 DSH |
251 | *) Tidy up PKCS#7 routines and add new functions to make it easier to |
252 | create PKCS7 structures containing multiple signers. Update smime | |
253 | application to support multiple signers. | |
254 | [Steve Henson] | |
255 | ||
121dd39f DSH |
256 | *) New -macalg option to pkcs12 utility to allow setting of an alternative |
257 | digest MAC. | |
258 | [Steve Henson] | |
259 | ||
856640b5 | 260 | *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC. |
b8f702a0 | 261 | Reorganize PBE internals to lookup from a static table using NIDs, |
6d3a1eac DSH |
262 | add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl: |
263 | EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative | |
264 | PRF which will be automatically used with PBES2. | |
856640b5 DSH |
265 | [Steve Henson] |
266 | ||
34b3c72e | 267 | *) Replace the algorithm specific calls to generate keys in "req" with the |
959e8dfe DSH |
268 | new API. |
269 | [Steve Henson] | |
270 | ||
399a6f0b DSH |
271 | *) Update PKCS#7 enveloped data routines to use new API. This is now |
272 | supported by any public key method supporting the encrypt operation. A | |
273 | ctrl is added to allow the public key algorithm to examine or modify | |
274 | the PKCS#7 RecipientInfo structure if it needs to: for RSA this is | |
275 | a no op. | |
276 | [Steve Henson] | |
28e4fe34 | 277 | |
03919683 DSH |
278 | *) Add a ctrl to asn1 method to allow a public key algorithm to express |
279 | a default digest type to use. In most cases this will be SHA1 but some | |
280 | algorithms (such as GOST) need to specify an alternative digest. The | |
281 | return value indicates how strong the prefernce is 1 means optional and | |
282 | 2 is mandatory (that is it is the only supported type). Modify | |
283 | ASN1_item_sign() to accept a NULL digest argument to indicate it should | |
284 | use the default md. Update openssl utilities to use the default digest | |
285 | type for signing if it is not explicitly indicated. | |
286 | [Steve Henson] | |
287 | ||
ee1d9ec0 DSH |
288 | *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New |
289 | EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant | |
290 | signing method from the key type. This effectively removes the link | |
291 | between digests and public key types. | |
292 | [Steve Henson] | |
293 | ||
d2027098 DSH |
294 | *) Add an OID cross reference table and utility functions. Its purpose is to |
295 | translate between signature OIDs such as SHA1WithrsaEncryption and SHA1, | |
296 | rsaEncryption. This will allow some of the algorithm specific hackery | |
297 | needed to use the correct OID to be removed. | |
298 | [Steve Henson] | |
299 | ||
492a9e24 DSH |
300 | *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO |
301 | structures for PKCS7_sign(). They are now set up by the relevant public | |
302 | key ASN1 method. | |
303 | [Steve Henson] | |
304 | ||
9ca7047d DSH |
305 | *) Add provisional EC pkey method with support for ECDSA and ECDH. |
306 | [Steve Henson] | |
307 | ||
ffb1ac67 DSH |
308 | *) Add support for key derivation (agreement) in the API, DH method and |
309 | pkeyutl. | |
310 | [Steve Henson] | |
311 | ||
3ba0885a DSH |
312 | *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support |
313 | public and private key formats. As a side effect these add additional | |
314 | command line functionality not previously available: DSA signatures can be | |
315 | generated and verified using pkeyutl and DH key support and generation in | |
316 | pkey, genpkey. | |
317 | [Steve Henson] | |
318 | ||
4700aea9 UM |
319 | *) BeOS support. |
320 | [Oliver Tappe <zooey@hirschkaefer.de>] | |
321 | ||
322 | *) New make target "install_html_docs" installs HTML renditions of the | |
323 | manual pages. | |
324 | [Oliver Tappe <zooey@hirschkaefer.de>] | |
325 | ||
f5cda4cb DSH |
326 | *) New utility "genpkey" this is analagous to "genrsa" etc except it can |
327 | generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to | |
328 | support key and parameter generation and add initial key generation | |
329 | functionality for RSA. | |
330 | [Steve Henson] | |
331 | ||
f733a5ef DSH |
332 | *) Add functions for main EVP_PKEY_method operations. The undocumented |
333 | functions EVP_PKEY_{encrypt,decrypt} have been renamed to | |
334 | EVP_PKEY_{encrypt,decrypt}_old. | |
335 | [Steve Henson] | |
336 | ||
0b6f3c66 DSH |
337 | *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public |
338 | key API, doesn't do much yet. | |
339 | [Steve Henson] | |
340 | ||
0b33dac3 DSH |
341 | *) New function EVP_PKEY_asn1_get0_info() to retrieve information about |
342 | public key algorithms. New option to openssl utility: | |
343 | "list-public-key-algorithms" to print out info. | |
344 | [Steve Henson] | |
345 | ||
33273721 BM |
346 | *) Implement the Supported Elliptic Curves Extension for |
347 | ECC ciphersuites from draft-ietf-tls-ecc-12.txt. | |
348 | [Douglas Stebila] | |
349 | ||
246e0931 DSH |
350 | *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or |
351 | EVP_CIPHER structures to avoid later problems in EVP_cleanup(). | |
352 | [Steve Henson] | |
353 | ||
3e4585c8 | 354 | *) New utilities pkey and pkeyparam. These are similar to algorithm specific |
f5cda4cb | 355 | utilities such as rsa, dsa, dsaparam etc except they process any key |
3e4585c8 | 356 | type. |
3e84b6e1 DSH |
357 | [Steve Henson] |
358 | ||
35208f36 DSH |
359 | *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New |
360 | functions EVP_PKEY_print_public(), EVP_PKEY_print_private(), | |
361 | EVP_PKEY_print_param() to print public key data from an EVP_PKEY | |
362 | structure. | |
363 | [Steve Henson] | |
364 | ||
448be743 DSH |
365 | *) Initial support for pluggable public key ASN1. |
366 | De-spaghettify the public key ASN1 handling. Move public and private | |
367 | key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate | |
368 | algorithm specific handling to a single module within the relevant | |
369 | algorithm directory. Add functions to allow (near) opaque processing | |
370 | of public and private key structures. | |
371 | [Steve Henson] | |
372 | ||
36ca4ba6 BM |
373 | *) Implement the Supported Point Formats Extension for |
374 | ECC ciphersuites from draft-ietf-tls-ecc-12.txt. | |
375 | [Douglas Stebila] | |
376 | ||
ddac1974 NL |
377 | *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members |
378 | for the psk identity [hint] and the psk callback functions to the | |
379 | SSL_SESSION, SSL and SSL_CTX structure. | |
380 | ||
381 | New ciphersuites: | |
382 | PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA, | |
383 | PSK-AES256-CBC-SHA | |
384 | ||
385 | New functions: | |
386 | SSL_CTX_use_psk_identity_hint | |
387 | SSL_get_psk_identity_hint | |
388 | SSL_get_psk_identity | |
389 | SSL_use_psk_identity_hint | |
390 | ||
391 | [Mika Kousa and Pasi Eronen of Nokia Corporation] | |
392 | ||
c7235be6 UM |
393 | *) Add RFC 3161 compliant time stamp request creation, response generation |
394 | and response verification functionality. | |
395 |
