11d01d37 | 5 | Changes between 0.9.8g and 0.9.9 [xx XXX xxxx] |
3ff55e96 | 6 | |
5ce278a7 BL |
7 | *) Removed effectively defunct crypto/store from the build. |
8 | [Ben Laurie] | |
9 | ||
10 | *) Revamp of STACK to provide stronger type-checking. Still to come: | |
11 | TXT_DB, bsearch(?), OBJ_bsearch, qsort, CRYPTO_EX_DATA, ASN1_VALUE, | |
12 | ASN1_STRING, CONF_VALUE. | |
13 | [Ben Laurie] | |
14 | ||
8671b898 BL |
15 | *) Add a new SSL_MODE_RELEASE_BUFFERS mode flag to release unused buffer |
16 | RAM on SSL connections. This option can save about 34k per idle SSL. | |
17 | [Nick Mathewson] | |
18 | ||
3c1d6bbc BL |
19 | *) Revamp of LHASH to provide stronger type-checking. Still to come: |
20 | STACK, TXT_DB, bsearch, qsort. | |
21 | [Ben Laurie] | |
22 | ||
4bd4afa3 BM |
23 | *) Not all of this is true any longer. |
24 | Will have to be updated to reflect all subsequent changes to cryptlib.c. | |
25 | --bodo | |
26 | ||
27 | ||
28 | To support arbitrarily-typed thread IDs, deprecate the existing | |
f7ccba3e GT |
29 | type-specific APIs for a general purpose CRYPTO_THREADID |
30 | interface. Applications can choose the thread ID | |
31 | callback type it wishes to register, as before; | |
32 | ||
33 | void CRYPTO_set_id_callback(unsigned long (*func)(void)); | |
34 | void CRYPTO_set_idptr_callback(void *(*func)(void)); | |
35 | ||
36 | but retrieval, copies, and comparisons of thread IDs are via | |
37 | type-independent interfaces; | |
38 | ||
39 | void CRYPTO_THREADID_set(CRYPTO_THREADID *id); | |
40 | void CRYPTO_THREADID_cmp(const CRYPTO_THREADID *id1, | |
41 | const CRYPTO_THREADID *id2); | |
42 | void CRYPTO_THREADID_cpy(CRYPTO_THREADID *dst, | |
43 | const CRYPTO_THREADID *src); | |
44 | ||
45 | Also, for code that needs a thread ID "value" for use in | |
46 | hash-tables or logging, a "hash" is available by; | |
47 | ||
48 | unsigned long CRYPTO_THREADID_hash(const CRYPTO_THREADID *id); | |
49 | ||
50 | This hash value is likely to be the thread ID anyway, but | |
51 | otherwise it will be unique if possible or as collision-free as | |
52 | possible if uniqueness can't be guaranteed on the target | |
53 | architecture. | |
54 | ||
55 | The following functions are deprecated; | |
56 | unsigned long (*CRYPTO_get_id_callback(void))(void); | |
57 | unsigned long CRYPTO_thread_id(void); | |
58 | ||
59 | As a consequence of the above, there are similar deprecations of | |
60 | BN_BLINDING functions in favour of CRYPTO_THREADID-based | |
61 | alternatives; | |
62 | ||
63 | #ifndef OPENSSL_NO_DEPRECATED | |
64 | unsigned long BN_BLINDING_get_thread_id(const BN_BLINDING *); | |
65 | void BN_BLINDING_set_thread_id(BN_BLINDING *, unsigned long); | |
66 | #endif | |
67 | void BN_BLINDING_set_thread(BN_BLINDING *); | |
68 | int BN_BLINDING_cmp_thread(const BN_BLINDING *, const | |
69 | CRYPTO_THREADID *); | |
70 | ||
71 | Also, the ERR_remove_state(int pid) API has been deprecated; | |
72 | ||
73 | #ifndef OPENSSL_NO_DEPRECATED | |
74 | void ERR_remove_state(unsigned long pid) | |
75 | #endif | |
76 | void ERR_remove_thread_state(CRYPTO_THREADID *tid); | |
77 | ||
78 | [Geoff Thorpe] | |
79 | ||
8931b30d DSH |
80 | *) Initial support for Cryptographic Message Syntax (aka CMS) based |
81 | on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility, | |
fd47c361 | 82 | support for data, signedData, compressedData, digestedData and |
eb9d8d8c DSH |
83 | encryptedData, envelopedData types included. Scripts to check against |
84 | RFC4134 examples draft and interop and consistency checks of many | |
85 | content types and variants. | |
8931b30d DSH |
86 | [Steve Henson] |
87 | ||
3df93571 | 88 | *) Add options to enc utility to support use of zlib compression BIO. |
8931b30d DSH |
89 | [Steve Henson] |
90 | ||
73980531 DSH |
91 | *) Extend mk1mf to support importing of options and assembly language |
92 | files from Configure script, currently only included in VC-WIN32. | |
93 | The assembly language rules can now optionally generate the source | |
94 | files from the associated perl scripts. | |
95 | [Steve Henson] | |
96 | ||
0e1dba93 DSH |
97 | *) Implement remaining functionality needed to support GOST ciphersuites. |
98 | Interop testing has been performed using CryptoPro implementations. | |
99 | [Victor B. Wagner <vitus@cryptocom.ru>] | |
100 | ||
0023adb4 AP |
101 | *) s390x assembler pack. |
102 | [Andy Polyakov] | |
103 | ||
4c7c5ff6 AP |
104 | *) ARMv4 assembler pack. ARMv4 refers to v4 and later ISA, not CPU |
105 | "family." | |
106 | [Andy Polyakov] | |
107 | ||
761772d7 BM |
108 | *) Implement Opaque PRF Input TLS extension as specified in |
109 | draft-rescorla-tls-opaque-prf-input-00.txt. Since this is not an | |
110 | official specification yet and no extension type assignment by | |
111 | IANA exists, this extension (for now) will have to be explicitly | |
112 | enabled when building OpenSSL by providing the extension number | |
113 | to use. For example, specify an option | |
114 | ||
115 | -DTLSEXT_TYPE_opaque_prf_input=0x9527 | |
116 | ||
117 | to the "config" or "Configure" script to enable the extension, | |
118 | assuming extension number 0x9527 (which is a completely arbitrary | |
119 | and unofficial assignment based on the MD5 hash of the Internet | |
120 | Draft). Note that by doing so, you potentially lose | |
121 | interoperability with other TLS implementations since these might | |
122 | be using the same extension number for other purposes. | |
123 | ||
124 | SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the | |
125 | opaque PRF input value to use in the handshake. This will create | |
126 | an interal copy of the length-'len' string at 'src', and will | |
127 | return non-zero for success. | |
128 | ||
129 | To get more control and flexibility, provide a callback function | |
130 | by using | |
131 | ||
132 | SSL_CTX_set_tlsext_opaque_prf_input_callback(ctx, cb) | |
133 | SSL_CTX_set_tlsext_opaque_prf_input_callback_arg(ctx, arg) | |
134 | ||
135 | where | |
136 | ||
137 | int (*cb)(SSL *, void *peerinput, size_t len, void *arg); | |
138 | void *arg; | |
139 | ||
140 | Callback function 'cb' will be called in handshakes, and is | |
141 | expected to use SSL_set_tlsext_opaque_prf_input() as appropriate. | |
142 | Argument 'arg' is for application purposes (the value as given to | |
143 | SSL_CTX_set_tlsext_opaque_prf_input_callback_arg() will directly | |
144 | be provided to the callback function). The callback function | |
145 | has to return non-zero to report success: usually 1 to use opaque | |
146 | PRF input just if possible, or 2 to enforce use of the opaque PRF | |
147 | input. In the latter case, the library will abort the handshake | |
148 | if opaque PRF input is not successfully negotiated. | |
149 | ||
150 | Arguments 'peerinput' and 'len' given to the callback function | |
151 | will always be NULL and 0 in the case of a client. A server will | |
152 | see the client's opaque PRF input through these variables if | |
153 | available (NULL and 0 otherwise). Note that if the server | |
154 | provides an opaque PRF input, the length must be the same as the | |
155 | length of the client's opaque PRF input. | |
156 | ||
157 | Note that the callback function will only be called when creating | |
158 | a new session (session resumption can resume whatever was | |
159 | previously negotiated), and will not be called in SSL 2.0 | |
160 | handshakes; thus, SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2) or | |
161 | SSL_set_options(ssl, SSL_OP_NO_SSLv2) is especially recommended | |
162 | for applications that need to enforce opaque PRF input. | |
163 | ||
164 | [Bodo Moeller] | |
165 | ||
81025661 DSH |
166 | *) Update ssl code to support digests other than SHA1+MD5 for handshake |
167 | MAC. | |
168 | ||
169 | [Victor B. Wagner <vitus@cryptocom.ru>] | |
170 | ||
6434abbf DSH |
171 | *) Add RFC4507 support to OpenSSL. This includes the corrections in |
172 | RFC4507bis. The encrypted ticket format is an encrypted encoded | |
173 | SSL_SESSION structure, that way new session features are automatically | |
174 | supported. | |
175 | ||
ba0e826d DSH |
176 | If a client application caches session in an SSL_SESSION structure |
177 | support is transparent because tickets are now stored in the encoded | |
178 | SSL_SESSION. | |
179 | ||
180 | The SSL_CTX structure automatically generates keys for ticket | |
181 | protection in servers so again support should be possible | |
6434abbf DSH |
182 | with no application modification. |
183 | ||
184 | If a client or server wishes to disable RFC4507 support then the option | |
185 | SSL_OP_NO_TICKET can be set. | |
186 | ||
187 | Add a TLS extension debugging callback to allow the contents of any client | |
188 | or server extensions to be examined. | |
ec5d7473 DSH |
189 | |
190 | This work was sponsored by Google. | |
6434abbf DSH |
191 | [Steve Henson] |
192 | ||
3c07d3a3 DSH |
193 | *) Final changes to avoid use of pointer pointer casts in OpenSSL. |
194 | OpenSSL should now compile cleanly on gcc 4.2 | |
195 | [Peter Hartley <pdh@utter.chaos.org.uk>, Steve Henson] | |
196 | ||
b948e2c5 DSH |
197 | *) Update SSL library to use new EVP_PKEY MAC API. Include generic MAC |
198 | support including streaming MAC support: this is required for GOST | |
199 | ciphersuite support. | |
200 | [Victor B. Wagner <vitus@cryptocom.ru>, Steve Henson] | |
201 | ||
9cfc8a9d DSH |
202 | *) Add option -stream to use PKCS#7 streaming in smime utility. New |
203 | function i2d_PKCS7_bio_stream() and PEM_write_PKCS7_bio_stream() | |
204 | to output in BER and PEM format. | |
205 | [Steve Henson] | |
206 | ||
47b71e6e DSH |
207 | *) Experimental support for use of HMAC via EVP_PKEY interface. This |
208 | allows HMAC to be handled via the EVP_DigestSign*() interface. The | |
209 | EVP_PKEY "key" in this case is the HMAC key, potentially allowing | |
2022cfe0 DSH |
210 | ENGINE support for HMAC keys which are unextractable. New -mac and |
211 | -macopt options to dgst utility. | |
47b71e6e DSH |
212 | [Steve Henson] |
213 | ||
d952c79a DSH |
214 | *) New option -sigopt to dgst utility. Update dgst to use |
215 | EVP_Digest{Sign,Verify}*. These two changes make it possible to use | |
216 | alternative signing paramaters such as X9.31 or PSS in the dgst | |
217 | utility. | |
218 | [Steve Henson] | |
219 | ||
fd5bc65c BM |
220 | *) Change ssl_cipher_apply_rule(), the internal function that does |
221 | the work each time a ciphersuite string requests enabling | |
222 | ("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or | |
223 | removing ("!foo+bar") a class of ciphersuites: Now it maintains | |
224 | the order of disabled ciphersuites such that those ciphersuites | |
225 | that most recently went from enabled to disabled not only stay | |
226 | in order with respect to each other, but also have higher priority | |
227 | than other disabled ciphersuites the next time ciphersuites are | |
228 | enabled again. | |
229 | ||
230 | This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable | |
231 | the same ciphersuites as with "HIGH" alone, but in a specific | |
232 | order where the PSK ciphersuites come first (since they are the | |
233 | most recently disabled ciphersuites when "HIGH" is parsed). | |
234 | ||
235 | Also, change ssl_create_cipher_list() (using this new | |
236 | funcionality) such that between otherwise identical | |
237 | cihpersuites, ephemeral ECDH is preferred over ephemeral DH in | |
238 | the default order. | |
239 | [Bodo Moeller] | |
240 | ||
0a05123a BM |
241 | *) Change ssl_create_cipher_list() so that it automatically |
242 | arranges the ciphersuites in reasonable order before starting | |
243 | to process the rule string. Thus, the definition for "DEFAULT" | |
244 | (SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but | |
245 | remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH". | |
246 | This makes it much easier to arrive at a reasonable default order | |
247 | in applications for which anonymous ciphers are OK (meaning | |
248 | that you can't actually use DEFAULT). | |
249 | [Bodo Moeller; suggested by Victor Duchovni] | |
250 | ||
52b8dad8 BM |
251 | *) Split the SSL/TLS algorithm mask (as used for ciphersuite string |
252 | processing) into multiple integers instead of setting | |
253 | "SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK", | |
254 | "SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer. | |
255 | (These masks as well as the individual bit definitions are hidden | |
256 | away into the non-exported interface ssl/ssl_locl.h, so this | |
257 | change to the definition of the SSL_CIPHER structure shouldn't | |
258 | affect applications.) This give us more bits for each of these | |
259 | categories, so there is no longer a need to coagulate AES128 and | |
260 | AES256 into a single algorithm bit, and to coagulate Camellia128 | |
261 | and Camellia256 into a single algorithm bit, which has led to all | |
262 | kinds of kludges. | |
263 | ||
264 | Thus, among other things, the kludge introduced in 0.9.7m and | |
265 | 0.9.8e for masking out AES256 independently of AES128 or masking | |
266 | out Camellia256 independently of AES256 is not needed here in 0.9.9. | |
267 | ||
268 | With the change, we also introduce new ciphersuite aliases that | |
269 | so far were missing: "AES128", "AES256", "CAMELLIA128", and | |
270 | "CAMELLIA256". | |
271 | [Bodo Moeller] | |
272 | ||
357d5de5 NL |
273 | *) Add support for dsa-with-SHA224 and dsa-with-SHA256. |
274 | Use the leftmost N bytes of the signature input if the input is | |
275 | larger than the prime q (with N being the size in bytes of q). | |
276 | [Nils Larsch] | |
277 | ||
11d8cdc6 DSH |
278 | *) Very *very* experimental PKCS#7 streaming encoder support. Nothing uses |
279 | it yet and it is largely untested. | |
280 | [Steve Henson] | |
281 | ||
06e2dd03 NL |
282 | *) Add support for the ecdsa-with-SHA224/256/384/512 signature types. |
283 | [Nils Larsch] | |
284 | ||
de121164 | 285 | *) Initial incomplete changes to avoid need for function casts in OpenSSL |
297e6f19 | 286 | some compilers (gcc 4.2 and later) reject their use. Safestack is |
a6fbcb42 | 287 | reimplemented. Update ASN1 to avoid use of legacy functions. |
de121164 DSH |
288 | [Steve Henson] |
289 | ||
3189772e AP |
290 | *) Win32/64 targets are linked with Winsock2. |
291 | [Andy Polyakov] | |
292 | ||
010fa0b3 DSH |
293 | *) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected |
294 | to external functions. This can be used to increase CRL handling | |
295 | efficiency especially when CRLs are very large by (for example) storing | |
296 | the CRL revoked certificates in a database. | |
297 | [Steve Henson] | |
298 | ||
5d20c4fb DSH |
299 | *) Overhaul of by_dir code. Add support for dynamic loading of CRLs so |
300 | new CRLs added to a directory can be used. New command line option | |
301 | -verify_return_error to s_client and s_server. This causes real errors | |
302 | to be returned by the verify callback instead of carrying on no matter | |
303 | what. This reflects the way a "real world" verify callback would behave. | |
304 | [Steve Henson] | |
305 | ||
306 | *) GOST engine, supporting several GOST algorithms and public key formats. | |
307 | Kindly donated by Cryptocom. | |
308 | [Cryptocom] | |
309 | ||
bc7535bc DSH |
310 | *) Partial support for Issuing Distribution Point CRL extension. CRLs |
311 | partitioned by DP are handled but no indirect CRL or reason partitioning | |
312 | (yet). Complete overhaul of CRL handling: now the most suitable CRL is | |
313 | selected via a scoring technique which handles IDP and AKID in CRLs. | |
314 | [Steve Henson] | |
315 | ||
316 | *) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which | |
317 | will ultimately be used for all verify operations: this will remove the | |
318 | X509_STORE dependency on certificate verification and allow alternative | |
319 | lookup methods. X509_STORE based implementations of these two callbacks. | |
320 | [Steve Henson] | |
321 | ||
f6e7d014 DSH |
322 | *) Allow multiple CRLs to exist in an X509_STORE with matching issuer names. |
323 | Modify get_crl() to find a valid (unexpired) CRL if possible. | |
324 | [Steve Henson] | |
325 | ||
edc54021 DSH |
326 | *) New function X509_CRL_match() to check if two CRLs are identical. Normally |
327 | this would be called X509_CRL_cmp() but that name is already used by | |
328 | a function that just compares CRL issuer names. Cache several CRL | |
329 | extensions in X509_CRL structure and cache CRLDP in X509. | |
330 | [Steve Henson] | |
331 | ||
450ea834 DSH |
332 | *) Store a "canonical" representation of X509_NAME structure (ASN1 Name) |
333 | this maps equivalent X509_NAME structures into a consistent structure. | |
334 | Name comparison can then be performed rapidly using memcmp(). | |
335 | [Steve Henson] | |
336 | ||
454dbbc5 DSH |
337 | *) Non-blocking OCSP request processing. Add -timeout option to ocsp |
338 | utility. | |
c1c6c0bf DSH |
339 | [Steve Henson] |
340 | ||
b7683e3a DSH |
341 | *) Allow digests to supply their own micalg string for S/MIME type using |
342 | the ctrl EVP_MD_CTRL_MICALG. | |
343 | [Steve Henson] | |
344 | ||
345 | *) During PKCS7 signing pass the PKCS7 SignerInfo structure to the | |
346 | EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN | |
347 | ctrl. It can then customise the structure before and/or after signing | |
348 | if necessary. | |
349 | [Steve Henson] | |
350 | ||
0ee2166c DSH |
351 | *) New function OBJ_add_sigid() to allow application defined signature OIDs |
352 | to be added to OpenSSLs internal tables. New function OBJ_sigid_free() | |
353 | to free up any added signature OIDs. | |
354 | [Steve Henson] | |
355 | ||
5ba4bf35 DSH |
356 | *) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(), |
357 | EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal | |
358 | digest and cipher tables. New options added to openssl utility: | |
359 | list-message-digest-algorithms and list-cipher-algorithms. | |
360 | [Steve Henson] | |
361 | ||
48fc582f BM |
362 | *) In addition to the numerical (unsigned long) thread ID, provide |
363 | for a pointer (void *) thread ID. This helps accomodate systems | |
364 | that do not provide an unsigned long thread ID. OpenSSL assumes | |
365 | it is in the same thread iff both the numerical and the pointer | |
366 | thread ID agree; so applications are just required to define one | |
367 | of them appropriately (e.g., by using a pointer to a per-thread | |
368 | memory object malloc()ed by the application for the pointer-type | |
369 | thread ID). Exactly analoguous to the existing functions | |
370 | ||
371 | void CRYPTO_set_id_callback(unsigned long (*func)(void)); | |
372 | unsigned long (*CRYPTO_get_id_callback(void))(void); | |
373 | unsigned long CRYPTO_thread_id(void); | |
374 | ||
375 | we now have additional functions | |
376 | ||
377 | void CRYPTO_set_idptr_callback(void *(*func)(void)); | |
378 | void *(*CRYPTO_get_idptr_callback(void))(void); | |
379 | void *CRYPTO_thread_idptr(void); | |
380 | ||
381 | also in <openssl/crypto.h>. The default value for | |
382 | CRYPTO_thread_idptr() if the application has not provided its own | |
383 | callback is &errno. | |
384 | [Bodo Moeller] | |
385 | ||
f7ccba3e GT |
386 | -- NOTE -- this change has been reverted and replaced with a |
387 | type-independent wrapper (ie. applications do not have to check | |
388 | two type-specific thread ID representations as implied in this | |
389 | change note). However, the "idptr" callback form described here | |
390 | can still be registered. Please see the more recent CHANGES note | |
391 | regarding CRYPTO_THREADID. [Geoff Thorpe] | |
392 | -- NOTE -- | |
393 | ||
c4e7870a BM |
394 | *) Change the array representation of binary polynomials: the list |
395 | of degrees of non-zero coefficients is now terminated with -1. | |
396 | Previously it was terminated with 0, which was also part of the | |
397 | value; thus, the array representation was not applicable to | |
398 | polynomials where t^0 has coefficient zero. This change makes | |
399 | the array representation useful in a more general context. | |
400 | [Douglas Stebila] | |
401 | ||
89bbe14c BM |
402 | *) Various modifications and fixes to SSL/TLS cipher string |
403 | handling. For ECC, the code now distinguishes between fixed ECDH | |
404 | with RSA certificates on the one hand and with ECDSA certificates | |
405 | on the other hand, since these are separate ciphersuites. The | |
406 | unused code for Fortezza ciphersuites has been removed. | |
407 | ||
408 | For consistency with EDH, ephemeral ECDH is now called "EECDH" | |
409 | (not "ECDHE"). For consistency with the code for DH | |
410 | certificates, use of ECDH certificates is now considered ECDH | |
411 | authentication, not RSA or ECDSA authentication (the latter is | |
412 | merely the CA's signing algorithm and not actively used in the | |
413 | protocol). | |
414 | ||
415 | The temporary ciphersuite alias "ECCdraft" is no longer | |
416 | available, and ECC ciphersuites are no longer excluded from "ALL" | |
417 | and "DEFAULT". The following aliases now exist for RFC 4492 | |
418 | ciphersuites, most of these by analogy with the DH case: | |
419 | ||
420 | kECDHr - ECDH cert, signed with RSA | |
421 | kECDHe - ECDH cert, signed with ECDSA | |
422 | kECDH - ECDH cert (signed with either RSA or ECDSA) | |
423 | kEECDH - ephemeral ECDH | |
424 | ECDH - ECDH cert or ephemeral ECDH | |
425 | ||
426 | aECDH - ECDH cert | |
427 | aECDSA - ECDSA cert | |
428 | ECDSA - ECDSA cert | |
429 | ||
430 | AECDH - anonymous ECDH | |
431 | EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH") | |

434 | ||
fb7b3932 DSH |
435 | *) Add additional S/MIME capabilities for AES and GOST ciphers if supported. |
436 | Use correct micalg parameters depending on digest(s) in signed message. | |
437 | [Steve Henson] | |
438 | ||
01b8b3c7 DSH |
439 | *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process |
440 | an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code. | |
441 | [Steve Henson] | |
de9fcfe3 | 442 | |
58aa573a | 443 | *) Initial engine support for EVP_PKEY_METHOD. New functions to permit |
c9777d26 DSH |
444 | an engine to register a method. Add ENGINE lookups for methods and |
445 | functional reference processing. | |
58aa573a DSH |
446 | [Steve Henson] |
447 | ||
91c9e621 DSH |
448 | *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of |
449 | EVP_{Sign,Verify}* which allow an application to customise the signature | |
450 | process. | |
451 | [Steve Henson] | |
452 | ||
55311921 DSH |
453 | *) New -resign option to smime utility. This adds one or more signers |
454 | to an existing PKCS#7 signedData structure. Also -md option to use an | |
455 | alternative message digest algorithm for signing. | |
456 | [Steve Henson] | |
457 | ||
a6e7fcd1 DSH |
458 | *) Tidy up PKCS#7 routines and add new functions to make it easier to |
459 | create PKCS7 structures containing multiple signers. Update smime | |
460 | application to support multiple signers. | |
461 | [Steve Henson] | |
462 | ||
121dd39f DSH |
463 | *) New -macalg option to pkcs12 utility to allow setting of an alternative |
464 | digest MAC. | |
465 | [Steve Henson] | |
466 | ||
856640b5 | 467 | *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC. |
b8f702a0 | 468 | Reorganize PBE internals to lookup from a static table using NIDs, |
6d3a1eac DSH |
469 | add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl: |
470 | EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative | |
471 | PRF which will be automatically used with PBES2. | |
856640b5 DSH |
472 | [Steve Henson] |
473 | ||
34b3c72e | 474 | *) Replace the algorithm specific calls to generate keys in "req" with the |
959e8dfe DSH |
475 | new API. |
476 | [Steve Henson] | |
477 | ||
399a6f0b DSH |
478 | *) Update PKCS#7 enveloped data routines to use new API. This is now |
479 | supported by any public key method supporting the encrypt operation. A | |
480 | ctrl is added to allow the public key algorithm to examine or modify | |
481 | the PKCS#7 RecipientInfo structure if it needs to: for RSA this is | |
482 | a no op. | |
483 | [Steve Henson] | |
28e4fe34 | 484 | |
03919683 DSH |
485 | *) Add a ctrl to asn1 method to allow a public key algorithm to express |
486 | a default digest type to use. In most cases this will be SHA1 but some | |
487 | algorithms (such as GOST) need to specify an alternative digest. The | |
488 | return value indicates how strong the prefernce is 1 means optional and | |
489 | 2 is mandatory (that is it is the only supported type). Modify | |
490 | ASN1_item_sign() to accept a NULL digest argument to indicate it should | |
491 | use the default md. Update openssl utilities to use the default digest | |
492 | type for signing if it is not explicitly indicated. | |
493 | [Steve Henson] | |
494 | ||
ee1d9ec0 DSH |
495 | *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New |
496 | EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant | |
497 | signing method from the key type. This effectively removes the link | |
498 | between digests and public key types. | |
499 | [Steve Henson] | |
500 | ||
d2027098 DSH |
501 | *) Add an OID cross reference table and utility functions. Its purpose is to |
502 | translate between signature OIDs such as SHA1WithrsaEncryption and SHA1, | |
503 | rsaEncryption. This will allow some of the algorithm specific hackery | |
504 | needed to use the correct OID to be removed. | |
505 | [Steve Henson] | |
506 | ||
492a9e24 DSH |
507 | *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO |
508 | structures for PKCS7_sign(). They are now set up by the relevant public | |
509 | key ASN1 method. | |
510 | [Steve Henson] | |
511 | ||
9ca7047d DSH |
512 | *) Add provisional EC pkey method with support for ECDSA and ECDH. |
513 | [Steve Henson] | |
514 | ||
ffb1ac67 DSH |
515 | *) Add support for key derivation (agreement) in the API, DH method and |
516 | pkeyutl. | |
517 | [Steve Henson] | |
518 | ||
3ba0885a DSH |
519 | *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support |
520 | public and private key formats. As a side effect these add additional | |
521 | command line functionality not previously available: DSA signatures can be | |
522 | generated and verified using pkeyutl and DH key support and generation in | |
523 | pkey, genpkey. | |
524 | [Steve Henson] | |
525 | ||
4700aea9 UM |
526 | *) BeOS support. |
527 | [Oliver Tappe <zooey@hirschkaefer.de>] | |
528 | ||
529 | *) New make target "install_html_docs" installs HTML renditions of the | |
530 | manual pages. | |
531 | [Oliver Tappe <zooey@hirschkaefer.de>] | |
532 | ||
f5cda4cb DSH |
533 | *) New utility "genpkey" this is analagous to "genrsa" etc except it can |
534 | generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to | |
535 | support key and parameter generation and add initial key generation | |
536 | functionality for RSA. | |
537 | [Steve Henson] | |
538 | ||
f733a5ef DSH |
539 | *) Add functions for main EVP_PKEY_method operations. The undocumented |
540 | functions EVP_PKEY_{encrypt,decrypt} have been renamed to | |
541 | EVP_PKEY_{encrypt,decrypt}_old. | |
542 | [Steve Henson] | |
543 | ||
0b6f3c66 DSH |
544 | *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public |
545 | key API, doesn't do much yet. | |
546 | [Steve Henson] | |
547 | ||
0b33dac3 DSH |
548 | *) New function EVP_PKEY_asn1_get0_info() to retrieve information about |
549 | public key algorithms. New option to openssl utility: | |
550 | "list-public-key-algorithms" to print out info. | |
551 | [Steve Henson] | |
552 | ||
33273721 BM |
553 | *) Implement the Supported Elliptic Curves Extension for |
554 | ECC ciphersuites from draft-ietf-tls-ecc-12.txt. | |
555 | [Douglas Stebila] | |
556 | ||
246e0931 DSH |
557 | *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or |
558 | EVP_CIPHER structures to avoid later problems in EVP_cleanup(). | |
559 | [Steve Henson] | |
560 | ||
3e4585c8 | 561 | *) New utilities pkey and pkeyparam. These are similar to algorithm specific |
f5cda4cb | 562 | utilities such as rsa, dsa, dsaparam etc except they process any key |
3e4585c8 | 563 | type. |
3e84b6e1 DSH |
564 | [Steve Henson] |
565 | ||
35208f36 DSH |
566 | *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New |
567 | functions EVP_PKEY_print_public(), EVP_PKEY_print_private(), | |
568 | EVP_PKEY_print_param() to print public key data from an EVP_PKEY | |
569 | structure. | |
570 | [Steve Henson] | |
571 | ||
448be743 DSH |
572 | *) Initial support for pluggable public key ASN1. |
573 | De-spaghettify the public key ASN1 handling. Move public and private | |
574 | key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate | |
575 | algorithm specific handling to a single module within the relevant | |
576 | algorithm directory. Add functions to allow (near) opaque processing | |
577 | of public and private key structures. | |
578 | [Steve Henson] | |
579 | ||
36ca4ba6 BM |
580 | *) Implement the Supported Point Formats Extension for |
581 | ECC ciphersuites from draft-ietf-tls-ecc-12.txt. | |
582 | [Douglas Stebila] | |
583 | ||
ddac1974 NL |
584 | *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members |
585 | for the psk identity [hint] and the psk callback functions to the | |
586 | SSL_SESSION, SSL and SSL_CTX structure. | |
587 | ||
588 | New ciphersuites: | |
589 | PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA, | |
590 | PSK-AES256-CBC-SHA | |
591 | ||
592 | New functions: | |
593 | SSL_CTX_use_psk_identity_hint | |
594 | SSL_get_psk_identity_hint | |
595 | SSL_get_psk_identity | |
596 | SSL_use_psk_identity_hint | |
597 | ||
598 | [Mika Kousa and Pasi Eronen of Nokia Corporation] | |
599 | ||
c7235be6 UM |
600 | *) Add RFC 3161 compliant time stamp request creation, response generation |
601 | and response verification functionality. | |
