a9d2bc49 | 5 | Changes between 0.9.6 and 0.9.7 [xx XXX 2001] |
a43cf9fa | 6 | |
b9a3ef4c RL |
7 | OpenSSL 0.9.6a/0.9.6b/0.9.6c (bugfix releases, 5 Apr 2001, 9 July 2001 |
8 | and 21 Dec 2001) and OpenSSL 0.9.7 were developed in parallel, based | |
9 | on OpenSSL 0.9.6. | |
e9ad0d2c | 10 | |
a9d2bc49 | 11 | Change log entries are tagged as follows: |
daba492c BM |
12 | -) applies to 0.9.6a/0.9.6b/0.9.6c only |
13 | *) applies to 0.9.6a/0.9.6b/0.9.6c and 0.9.7 | |
a9d2bc49 BM |
14 | +) applies to 0.9.7 only |
15 | ||
acfe628b LJ |
16 | *) Make removal from session cache (SSL_CTX_remove_session()) more robust: |
17 | check whether we deal with a copy of a session and do not delete from | |
18 | the cache in this case. Problem reported by "Izhar Shoshani Levi" | |
19 | <izhar@checkpoint.com>. | |
20 | [Lutz Jaenicke] | |
21 | ||
22 | *) Do not store session data into the internal session cache, if it | |
4de920c9 LJ |
23 | is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP |
24 | flag is set). Proposed by Aslam <aslam@funk.com>. | |
25 | [Lutz Jaenicke] | |
26 | ||
3cd039dd RL |
27 | +) Support for crypto accelerator cards from Accelerated Encryption |
28 | Processing, www.aep.ie. (Use engine 'aep') | |
29 | The support was copied from 0.9.6c [engine] and adapted/corrected | |
30 | to work with the new engine framework. | |
31 | [AEP Inc. and Richard Levitte] | |
32 | ||
33 | +) Support for SureWare crypto accelerator cards from Baltimore | |
34 | Technologies. (Use engine 'sureware') | |
35 | The support was copied from 0.9.6c [engine] and adapted | |
36 | to work with the new engine framework. | |
37 | [Richard Levitte] | |
38 | ||
b9a3ef4c RL |
39 | *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested |
40 | value is 0. | |
41 | [Richard Levitte] | |
42 | ||
1199e2d8 RL |
43 | +) Have the CHIL engine fork-safe (as defined by nCipher) and actually |
44 | make the newer ENGINE framework commands for the CHIL engine work. | |
45 | [Toomas Kiisk <vix@cyber.ee> and Richard Levitte] | |
46 | ||
a3fffd64 RL |
47 | +) Make it possible to produce shared libraries on ReliantUNIX. |
48 | [Robert Dahlem <Robert.Dahlem@ffm2.siemens.de> via Richard Levitte] | |
49 | ||
f14845d9 RL |
50 | *) Add the configuration target linux-s390x. |
51 | [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte] | |
52 | ||
80bb905d RL |
53 | +) Add the configuration target debug-linux-ppro. |
54 | Make 'openssl rsa' use the general key loading routines | |
55 | implemented in apps.c, and make those routines able to | |
56 | handle the key format FORMAT_NETSCAPE and the variant | |
57 | FORMAT_IISSGC. | |
58 | [Toomas Kiisk <vix@cyber.ee> via Richard Levitte] | |
59 | ||
60 | *) Fix a crashbug and a logic bug in hwcrhk_load_pubkey(). | |
61 | [Toomas Kiisk <vix@cyber.ee> via Richard Levitte] | |
62 | ||
8242a6a9 RL |
63 | +) Add -keyform to rsautl, and document -engine. |
64 | [Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>] | |
65 | ||
a14e2d9d BM |
66 | +) Change BIO_new_file (crypto/bio/bss_file.c) to use new |
67 | BIO_R_NO_SUCH_FILE error code rather than the generic | |
68 | ERR_R_SYS_LIB error code if fopen() fails with ENOENT. | |
69 | [Ben Laurie] | |
70 | ||
71 | +) Add new functions | |
72 | ERR_peek_last_error | |
73 | ERR_peek_last_error_line | |
74 | ERR_peek_last_error_line_data. | |
75 | These are similar to | |
76 | ERR_peek_error | |
77 | ERR_peek_error_line | |
78 | ERR_peek_error_line_data, | |
79 | but report on the latest error recorded rather than the first one | |
80 | still in the error queue. | |
81 | [Ben Laurie, Bodo Moeller] | |
82 | ||
df5eaa8a DSH |
83 | +) default_algorithms option in ENGINE config module. This allows things |
84 | like: | |
85 | default_algorithms = ALL | |
86 | default_algorithms = RSA, DSA, RAND, CIPHERS, DIGESTS | |
87 | [Steve Henson] | |
88 | ||
c9501c22 DSH |
89 | +) Prelminary ENGINE config module. |
90 | [Steve Henson] | |
91 | ||
8c74b5e5 BM |
92 | *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of |
93 | ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag | |
94 | variable as an indication that a ClientHello message has been | |
95 | received. As the flag value will be lost between multiple | |
96 | invocations of ssl3_accept when using non-blocking I/O, the | |
97 | function may not be aware that a handshake has actually taken | |
98 | place, thus preventing a new session from being added to the | |
99 | session cache. | |
100 | ||
101 | To avoid this problem, we now set s->new_session to 2 instead of | |
102 | using a local variable. | |
103 | [Lutz Jaenicke, Bodo Moeller] | |
104 | ||
c59ba5b5 BM |
105 | *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c) |
106 | if the SSL_R_LENGTH_MISMATCH error is detected. | |
107 | [Geoff Thorpe, Bodo Moeller] | |
108 | ||
bc37d996 DSH |
109 | +) New experimental application configuration code. |
110 | [Steve Henson] | |
111 | ||
d59fb0dd BM |
112 | *) New 'shared_ldflag' column in Configure platform table. |
113 | [Richard Levitte] | |
114 | ||
e5d6528a BM |
115 | *) Fix EVP_CIPHER_mode macro. |
116 | ["Dan S. Camper" <dan@bti.net>] | |
117 | ||
6f9079fd RL |
118 | +) Change the AES code to follow the same name structure as all other |
119 | symmetric ciphers, and behave the same way. Move everything to | |
120 | the directory crypto/aes, thereby obsoleting crypto/rijndael. | |
121 | [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte] | |
122 | ||
dcbbf83d UM |
123 | *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown |
124 | type, we must throw them away by setting rr->length to 0. | |
125 | [D P Chang <dpc@qualys.com>] | |
126 | ||
3c89d78d BM |
127 | -) OpenSSL 0.9.6c released [21 dec 2001] |
128 | ||
7c517a04 BL |
129 | +) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c. |
130 | [Ben Laurie and Theo de Raadt] | |
131 | ||
66df02fd BM |
132 | *) Fix BN_rand_range bug pointed out by Dominikus Scherkl |
133 | <Dominikus.Scherkl@biodata.com>. (The previous implementation | |
134 | worked incorrectly for those cases where range = 10..._2 and | |
135 | 3*range is two bits longer than range.) | |
136 | [Bodo Moeller] | |
137 | ||
b5348a09 BM |
138 | *) Only add signing time to PKCS7 structures if it is not already |
139 | present. | |
f3e24bad DSH |
140 | [Steve Henson] |
141 | ||
35e25255 BM |
142 | *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce", |
143 | OBJ_ld_ce should be OBJ_id_ce. | |
144 | Also some ip-pda OIDs in crypto/objects/objects.txt were | |
145 | incorrect (cf. RFC 3039). | |
146 | [Matt Cooper, Frederic Giudicelli, Bodo Moeller] | |
147 | ||
21a85f19 DSH |
148 | +) Add option to output public keys in req command. |
149 | [Massimiliano Pala madwolf@openca.org] | |
150 | ||
883b0c22 BM |
151 | *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid() |
152 | returns early because it has nothing to do. | |
153 | [Andy Schneider <andy.schneider@bjss.co.uk>] | |
154 | ||
155 | *) [In 0.9.6c-engine and 0.9.7 release:] | |
156 | Fix mutex callback return values in crypto/engine/hw_ncipher.c. | |
157 | [Andy Schneider <andy.schneider@bjss.co.uk>] | |
158 | ||
898f856c BM |
159 | -) [In 0.9.6c-engine release:] |
160 | Add support for Cryptographic Appliance's keyserver technology. | |
161 | (Use engine 'keyclient') | |
162 | [Cryptographic Appliances and Geoff Thorpe] | |
163 | ||
1d4581c2 BM |
164 | *) Add a configuration entry for OS/390 Unix. The C compiler 'c89' |
165 | is called via tools/c89.sh because arguments have to be | |
166 | rearranged (all '-L' options must appear before the first object | |
167 | modules). | |
168 | [Richard Shapiro <rshapiro@abinitio.com>] | |
169 | ||
76c4336c BM |
170 | +) Use wNAFs in EC_POINTs_mul() for improved efficiency |
171 | (up to about 10% better than before for P-192 and P-224). | |
3ba1f111 BM |
172 | [Bodo Moeller] |
173 | ||
83978bd3 BM |
174 | -) [In 0.9.6c-engine release:] |
175 | Add support for Broadcom crypto accelerator cards, backported | |
176 | from 0.9.7. | |
177 | [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox] | |
178 | ||
179 | -) [In 0.9.6c-engine release:] | |
180 | Add support for SureWare crypto accelerator cards from | |
181 | Baltimore Technologies. (Use engine 'sureware') | |
182 | [Baltimore Technologies and Mark Cox] | |
183 | ||
184 | -) [In 0.9.6c-engine release:] | |
185 | Add support for crypto accelerator cards from Accelerated | |
186 | Encryption Processing, www.aep.ie. (Use engine 'aep') | |
187 | [AEP Inc. and Mark Cox] | |
188 | ||
c5571db0 BM |
189 | *) Add a configuration entry for gcc on UnixWare. |
190 | [Gary Benson <gbenson@redhat.com>] | |
191 | ||
7aa983c6 BM |
192 | +) New functions/macros |
193 | ||
194 | SSL_CTX_set_msg_callback(ctx, cb) | |
195 | SSL_CTX_set_msg_callback_arg(ctx, arg) | |
196 | SSL_set_msg_callback(ssl, cb) | |
197 | SSL_set_msg_callback_arg(ssl, arg) | |
198 | ||
199 | to request calling a callback function | |
200 | ||
201 | void cb(int write_p, int version, int content_type, | |
202 | const void *buf, size_t len, SSL *ssl, void *arg) | |
203 | ||
204 | whenever a protocol message has been completely received | |
205 | (write_p == 0) or sent (write_p == 1). Here 'version' is the | |
206 | protocol version according to which the SSL library interprets | |
207 | the current protocol message (SSL2_VERSION, SSL3_VERSION, or | |
208 | TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or | |
209 | the content type as defined in the SSL 3.0/TLS 1.0 protocol | |
210 | specification (change_cipher_spec(20), alert(21), handshake(22)). | |
211 | 'buf' and 'len' point to the actual message, 'ssl' to the | |
212 | SSL object, and 'arg' is the application-defined value set by | |
213 | SSL[_CTX]_set_msg_callback_arg(). | |
214 | ||
215 | 'openssl s_client' and 'openssl s_server' have new '-msg' options | |
216 | to enable a callback that displays all protocol messages. | |
217 | [Bodo Moeller] | |
218 | ||
219 | *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake | |
220 | messages are stored in a single piece (fixed-length part and | |
221 | variable-length part combined) and fix various bugs found on the way. | |
222 | [Bodo Moeller] | |
223 | ||
a7b42009 RL |
224 | +) Change the shared library support so shared libraries are built as |
225 | soon as the corresponding static library is finished, and thereby get | |
226 | openssl and the test programs linked against the shared library. | |
227 | This still only happens when the keyword "shard" has been given to | |
228 | the configuration scripts. | |
229 | ||
230 | NOTE: shared library support is still an experimental thing, and | |
231 | backward binary compatibility is still not guaranteed. | |
232 | ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte] | |
233 | ||
7d5b04db DSH |
234 | +) Add support for Subject Information Access extension. |
235 | [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>] | |
236 | ||
48b0cf8b BM |
237 | +) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero |
238 | additional bytes when new memory had to be allocated, not just | |
239 | when reusing an existing buffer. | |
240 | [Bodo Moeller] | |
241 | ||
c602e7f4 BM |
242 | *) Disable caching in BIO_gethostbyname(), directly use gethostbyname() |
243 | instead. BIO_gethostbyname() does not know what timeouts are | |
48b0cf8b | 244 | appropriate, so entries would stay in cache even when they have |
c602e7f4 BM |
245 | become invalid. |
246 | [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com> | |
247 | ||
1fc6d41b DSH |
248 | +) New command line and configuration option 'utf8' for the req command. |
249 | This allows field values to be specified as UTF8 strings. | |
250 | [Steve Henson] | |
251 | ||
0e211563 BL |
252 | +) Add -multi and -mr options to "openssl speed" - giving multiple parallel |
253 | runs for the former and machine-readable output for the latter. | |
254 | [Ben Laurie] | |
255 | ||
89da653f BM |
256 | +) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion |
257 | of the e-mail address in the DN (i.e., it will go into a certificate | |
258 | extension only). The new configuration file option 'email_in_dn = no' | |
259 | has the same effect. | |
260 | [Massimiliano Pala madwolf@openca.org] | |
261 | ||
ba1c6022 BM |
262 | *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when |
263 | faced with a pathologically small ClientHello fragment that does | |
264 | not contain client_version: Instead of aborting with an error, | |
265 | simply choose the highest available protocol version (i.e., | |
266 | TLS 1.0 unless it is disabled). In practice, ClientHello | |
267 | messages are never sent like this, but this change gives us | |
268 | strictly correct behaviour at least for TLS. | |
269 | [Bodo Moeller] | |
270 | ||
c2e4f17c | 271 | +) Change all functions with names starting with des_ to be starting |
12852213 | 272 | with DES_ instead. Add wrappers that are compatible with libdes, |
2d57b73a RL |
273 | but are named _ossl_old_des_*. Finally, add macros that map the |
274 | des_* symbols to the corresponding _ossl_old_des_*. | |
12852213 RL |
275 | |
276 | All this is done because there are increasing clashes with libdes | |
a8b94d64 BM |
277 | and other DES libraries that are currently used by other projects. |
278 | The old libdes interface (including crypt()) is provided if | |
279 | <openssl/des_old.h> is included. For now, this automatically | |
a14e2d9d | 280 | happens in <openssl/des.h> unless OPENSSL_DISABLE_OLD_DES_SUPPORT is |
a8b94d64 | 281 | defined. Note that crypt() is no longer declared in <openssl/des.h>. |
c2e4f17c RL |
282 | |
283 | NOTE: This is a major break of an old API into a new one. Software | |
284 | authors are encouraged to switch to the DES_ style functions. Some | |
285 | time in the future, des_old.h and the libdes compatibility functions | |
286 | will be completely removed. | |
287 | [Richard Levitte] | |
288 | ||
979689aa BM |
289 | *) Fix SSL handshake functions and SSL_clear() such that SSL_clear() |
290 | never resets s->method to s->ctx->method when called from within | |
291 | one of the SSL handshake functions. | |
292 | [Bodo Moeller; problem pointed out by Niko Baric] | |
293 | ||
f1558bb4 DSH |
294 | +) Test for certificates which contain unsupported critical extensions. |
295 | If such a certificate is found during a verify operation it is | |
296 | rejected by default: this behaviour can be overridden by either | |
297 | handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or | |
298 | by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function | |
299 | X509_supported_extension() has also been added which returns 1 if a | |
300 | particular extension is supported. | |
301 | [Steve Henson] | |
302 | ||
a661b653 BM |
303 | *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert |
304 | (sent using the client's version number) if client_version is | |
305 | smaller than the protocol version in use. Also change | |
306 | ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if | |
307 | the client demanded SSL 3.0 but only TLS 1.0 is enabled; then | |
308 | the client will at least see that alert. | |
309 | [Bodo Moeller] | |
310 | ||
581f1c84 DSH |
311 | +) Modify the behaviour of EVP cipher functions in similar way to digests |
312 | to retain compatibility with existing code. | |
313 | [Steve Henson] | |
314 | ||
20d2186c | 315 | +) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain |
50d194af DSH |
316 | compatibility with existing code. In particular the 'ctx' parameter does |
317 | not have to be to be initialized before the call to EVP_DigestInit() and | |
318 | it is tidied up after a call to EVP_DigestFinal(). New function | |
319 | EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function | |
320 | EVP_MD_CTX_copy() changed to not require the destination to be | |
321 | initialized valid and new function EVP_MD_CTX_copy_ex() added which | |
322 | requires the destination to be valid. | |
323 | ||
324 | Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(), | |
325 | EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex(). | |
20d2186c DSH |
326 | [Steve Henson] |
327 | ||
48948d53 BM |
328 | +) Change ssl3_get_message (ssl/s3_both.c) and the functions using it |
329 | so that complete 'Handshake' protocol structures are kept in memory | |
330 | instead of overwriting 'msg_type' and 'length' with 'body' data. | |
331 | [Bodo Moeller] | |
332 | ||
333 | *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation | |
334 | correctly. | |
335 | [Bodo Moeller] | |
336 | ||
285046ec RL |
337 | +) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32. |
338 | [Massimo Santin via Richard Levitte] | |
339 | ||
07cee702 GT |
340 | +) Major restructuring to the underlying ENGINE code. This includes |
341 | reduction of linker bloat, separation of pure "ENGINE" manipulation | |
342 | (initialisation, etc) from functionality dealing with implementations | |
343 | of specific crypto iterfaces. This change also introduces integrated | |
344 | support for symmetric ciphers and digest implementations - so ENGINEs | |
345 | can now accelerate these by providing EVP_CIPHER and EVP_MD | |
346 | implementations of their own. This is detailed in crypto/engine/README | |
347 | as it couldn't be adequately described here. However, there are a few | |
348 | API changes worth noting - some RSA, DSA, DH, and RAND functions that | |
349 | were changed in the original introduction of ENGINE code have now | |
350 | reverted back - the hooking from this code to ENGINE is now a good | |
351 | deal more passive and at run-time, operations deal directly with | |
352 | RSA_METHODs, DSA_METHODs (etc) as they did before, rather than | |
353 | dereferencing through an ENGINE pointer any more. Also, the ENGINE | |
354 | functions dealing with BN_MOD_EXP[_CRT] handlers have been removed - | |
355 | they were not being used by the framework as there is no concept of a | |
356 | BIGNUM_METHOD and they could not be generalised to the new | |
357 | 'ENGINE_TABLE' mechanism that underlies the new code. Similarly, | |
358 | ENGINE_cpy() has been removed as it cannot be consistently defined in | |
359 | the new code. | |
360 | [Geoff Thorpe] | |
361 | ||
d46c1a81 DSH |
362 | +) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds. |
363 | [Steve Henson] | |
364 | ||
89eeccac RL |
365 | +) Change mkdef.pl to sort symbols that get the same entry number, |
366 | and make sure the automatically generated functions ERR_load_* | |
367 | become part of libeay.num as well. | |
368 | [Richard Levitte] | |
369 | ||
3b0b5aba BM |
370 | *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a |
371 | client receives HelloRequest while in a handshake. | |
372 | [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>] | |
373 | ||
6b0e9fac BM |
374 | +) New function SSL_renegotiate_pending(). This returns true once |
375 | renegotiation has been requested (either SSL_renegotiate() call | |
376 | or HelloRequest/ClientHello receveived from the peer) and becomes | |
377 | false once a handshake has been completed. | |
378 | (For servers, SSL_renegotiate() followed by SSL_do_handshake() | |
379 | sends a HelloRequest, but does not ensure that a handshake takes | |
380 | place. SSL_renegotiate_pending() is useful for checking if the | |
381 | client has followed the request.) | |
382 | [Bodo Moeller] | |
383 | ||
384 | +) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION. | |
385 | By default, clients may request session resumption even during | |
386 | renegotiation (if session ID contexts permit); with this option, | |
387 | session resumption is possible only in the first handshake. | |

390 | *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C |
391 | should end in 'break', not 'goto end' which circuments various | |
b49124f6 BM |
392 | cleanups done in state SSL_ST_OK. But session related stuff |
393 | must be disabled for SSL_ST_OK in the case that we just sent a | |
394 | HelloRequest. | |
2260ad21 BM |
395 | |
396 | Also avoid some overhead by not calling ssl_init_wbio_buffer() | |
397 | before just sending a HelloRequest. | |

400 | *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't |
401 | reveal whether illegal block cipher padding was found or a MAC | |
402 | verification error occured. (Neither SSLerr() codes nor alerts | |
403 | are directly visible to potential attackers, but the information | |
404 | may leak via logfiles.) | |
405 | ||
406 | Similar changes are not required for the SSL 2.0 implementation | |
407 | because the number of padding bytes is sent in clear for SSL 2.0, | |
408 | and the extra bytes are just ignored. However ssl/s2_pkt.c | |
409 | failed to verify that the purported number of padding bytes is in | |
410 | the legal range. | |

416 | +) Make maximum certificate chain size accepted from the peer application |
417 | settable (SSL*_get/set_max_cert_list()), as proposed by | |
418 | "Douglas E. Engert" <deengert@anl.gov>. | |

429 | *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid |
430 | 'wristwatch attack' using huge encoding parameters (cf. | |
431 | James H. Manger's CRYPTO 2001 paper). Note that the | |
432 | RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use | |
e3fefbfd | 433 | encoding parameters and hence was not vulnerable. |

4450107a | 436 | +) Add a "destroy" handler to ENGINEs that allows structural cleanup to |
908efd3b GT |
437 | be done prior to destruction. Use this to unload error strings from |
438 | ENGINEs that load their own error strings. NB: This adds two new API | |
439 | functions to "get" and "set" this destroy handler in an ENGINE. | |

908efd3b | 441 | |
4450107a | 442 | +) Alter all existing ENGINE implementations (except "openssl" and |
541814c4 GT |
443 | "openbsd") to dynamically instantiate their own error strings. This |
444 | makes them more flexible to be built both as statically-linked ENGINEs | |
445 | and self-contained shared-libraries loadable via the "dynamic" ENGINE. | |
446 | Also, add stub code to each that makes building them as self-contained | |
447 | shared-libraries easier (see README.ENGINE). | |
448 | [Geoff Thorpe] | |
449 | ||
4450107a | 450 | +) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE |
541814c4 GT |
451 | implementations into applications that are completely implemented in |
452 | self-contained shared-libraries. The "dynamic" ENGINE exposes control | |
453 | commands that can be used to configure what shared-library to load and | |
454 | to control aspects of the way it is handled. Also, made an update to | |
455 | the README.ENGINE file that brings its information up-to-date and | |
456 | provides some information and instructions on the "dynamic" ENGINE | |
457 | (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc). | |
