4 | ||
1c5dc844 DSH |
5 | Changes between 0.9.8b and 0.9.8c [xx XXX xxxx] |
6 | ||
7 | *) | |
8 | ||
f871949e | 9 | Changes between 0.9.8a and 0.9.8b [04 May 2006] |
d8b408b1 | 10 | |
cbb0b734 DSH |
11 | *) When applying a cipher rule check to see if string match is an explicit |
12 | cipher suite and only match that one cipher suite if it is. | |
13 | [Steve Henson] | |
14 | ||
217382d5 DSH |
15 | *) Link in manifests for VC++ if needed. |
16 | [Austin Ziegler <halostatue@gmail.com>] | |
17 | ||
bc932045 | 18 | *) Update support for ECC-based TLS ciphersuites according to |
5586a71a BM |
19 | draft-ietf-tls-ecc-12.txt with proposed changes (but without |
20 | TLS extensions, which are supported starting with the 0.9.9 | |
21 | branch, not in the OpenSSL 0.9.8 branch). | |
bc932045 BM |
22 | [Douglas Stebila] |
23 | ||
23d43aae BM |
24 | *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support |
25 | opaque EVP_CIPHER_CTX handling. | |
26 | [Steve Henson] | |
27 | ||
7614f0e5 DSH |
28 | *) Fixes and enhancements to zlib compression code. We now only use |
29 | "zlib1.dll" and use the default __cdecl calling convention on Win32 | |
30 | to conform with the standards mentioned here: | |
31 | http://www.zlib.net/DLL_FAQ.txt | |
32 | Static zlib linking now works on Windows and the new --with-zlib-include | |
33 | --with-zlib-lib options to Configure can be used to supply the location | |
34 | of the headers and library. Gracefully handle case where zlib library | |
35 | can't be loaded. | |
36 | [Steve Henson] | |
37 | ||
feef17fd DSH |
38 | *) Several fixes and enhancements to the OID generation code. The old code |
39 | sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't | |
40 | handle numbers larger than ULONG_MAX, truncated printing and had a | |
41 | non standard OBJ_obj2txt() behaviour. | |
42 | [Steve Henson] | |
43 | ||
abb0c2bb DSH |
44 | *) Add support for building of engines under engine/ as shared libraries |
45 | under VC++ build system. | |
46 | [Steve Henson] | |
47 | ||
d3afc92b RL |
48 | *) Corrected the numerous bugs in the Win32 path splitter in DSO. |
49 | Hopefully, we will not see any false combination of paths any more. | |
50 | [Richard Levitte] | |
51 | ||
64932f9e MC |
52 | Changes between 0.9.8 and 0.9.8a [11 Oct 2005] |
53 | ||
54 | *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING | |
55 | (part of SSL_OP_ALL). This option used to disable the | |
56 | countermeasure against man-in-the-middle protocol-version | |
57 | rollback in the SSL 2.0 server implementation, which is a bad | |
802c0146 | 58 | idea. (CVE-2005-2969) |
64932f9e MC |
59 | |
60 | [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center | |
61 | for Information Security, National Institute of Advanced Industrial | |
62 | Science and Technology [AIST], Japan)] | |
750cb3d2 | 63 | |
0fce007b DSH |
64 | *) Add two function to clear and return the verify parameter flags. |
65 | [Steve Henson] | |
66 | ||
3c0e39c5 NL |
67 | *) Keep cipherlists sorted in the source instead of sorting them at |
68 | runtime, thus removing the need for a lock. | |
69 | [Nils Larsch] | |
70 | ||
19fddebf | 71 | *) Avoid some small subgroup attacks in Diffie-Hellman. |
60864221 BL |
72 | [Nick Mathewson and Ben Laurie] |
73 | ||
74 | *) Add functions for well-known primes. | |
75 | [Nick Mathewson] | |
9ddb11f1 | 76 | |
98e98614 AP |
77 | *) Extended Windows CE support. |
78 | [Satoshi Nakamura and Andy Polyakov] | |
79 | ||
222f2246 DSH |
80 | *) Initialize SSL_METHOD structures at compile time instead of during |
81 | runtime, thus removing the need for a lock. | |
82 | [Steve Henson] | |
83 | ||
1682e8fb DSH |
84 | *) Make PKCS7_decrypt() work even if no certificate is supplied by |
85 | attempting to decrypt each encrypted key in turn. Add support to | |
86 | smime utility. | |
87 | [Steve Henson] | |
750cb3d2 | 88 | |
f254b540 | 89 | Changes between 0.9.7h and 0.9.8 [05 Jul 2005] |
12bdb643 | 90 | |
1d01c9d4 RL |
91 | *) Add libcrypto.pc and libssl.pc for those who feel they need them. |
92 | [Richard Levitte] | |
93 | ||
94 | *) Change CA.sh and CA.pl so they don't bundle the CSR and the private | |
95 | key into the same file any more. | |
96 | [Richard Levitte] | |
97 | ||
e32ea818 AP |
98 | *) Add initial support for Win64, both IA64 and AMD64/x64 flavors. |
99 | [Andy Polyakov] | |
100 | ||
09c1a425 DSH |
101 | *) Add -utf8 command line and config file option to 'ca'. |
102 | [Stefan <stf@udoma.org] | |
103 | ||
1d01c9d4 RL |
104 | *) Removed the macro des_crypt(), as it seems to conflict with some |
105 | libraries. Use DES_crypt(). | |
106 | [Richard Levitte] | |
107 | ||
a4578a54 GT |
108 | *) Correct naming of the 'chil' and '4758cca' ENGINEs. This |
109 | involves renaming the source and generated shared-libs for | |
110 | both. The engines will accept the corrected or legacy ids | |
111 | ('ncipher' and '4758_cca' respectively) when binding. NB, | |
112 | this only applies when building 'shared'. | |
113 | [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe] | |
114 | ||
b6995add DSH |
115 | *) Add attribute functions to EVP_PKEY structure. Modify |
116 | PKCS12_create() to recognize a CSP name attribute and | |
117 | use it. Make -CSP option work again in pkcs12 utility. | |
118 | [Steve Henson] | |
119 | ||
800e400d NL |
120 | *) Add new functionality to the bn blinding code: |
121 | - automatic re-creation of the BN_BLINDING parameters after | |
122 | a fixed number of uses (currently 32) | |
123 | - add new function for parameter creation | |
124 | - introduce flags to control the update behaviour of the | |
125 | BN_BLINDING parameters | |
126 | - hide BN_BLINDING structure | |
127 | Add a second BN_BLINDING slot to the RSA structure to improve | |
128 | performance when a single RSA object is shared among several | |
129 | threads. | |
130 | [Nils Larsch] | |
131 | ||
36d16f8e BL |
132 | *) Add support for DTLS. |
133 | [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie] | |
134 | ||
dc0ed30c NL |
135 | *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1) |
136 | to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file() | |
137 | [Walter Goulet] | |
138 | ||
6049399b NL |
139 | *) Remove buggy and incompletet DH cert support from |
140 | ssl/ssl_rsa.c and ssl/s3_both.c | |
141 | [Nils Larsch] | |
142 | ||
12bdb643 NL |
143 | *) Use SHA-1 instead of MD5 as the default digest algorithm for |
144 | the apps/openssl applications. | |
145 | [Nils Larsch] | |
4d94ae00 | 146 | |
41a15c4f BL |
147 | *) Compile clean with "-Wall -Wmissing-prototypes |
148 | -Wstrict-prototypes -Wmissing-declarations -Werror". Currently | |
149 | DEBUG_SAFESTACK must also be set. | |
150 | [Ben Laurie] | |
151 | ||
c9a112f5 | 152 | *) Change ./Configure so that certain algorithms can be disabled by default. |
ecc5ef87 BM |
153 | The new counterpiece to "no-xxx" is "enable-xxx". |
154 | ||
155 | The patented RC5 and MDC2 algorithms will now be disabled unless | |
156 | "enable-rc5" and "enable-mdc2", respectively, are specified. | |
157 | ||
158 | (IDEA remains enabled despite being patented. This is because IDEA | |
159 | is frequently required for interoperability, and there is no license | |
160 | fee for non-commercial use. As before, "no-idea" can be used to | |
161 | avoid this algorithm.) | |
162 | ||
c9a112f5 BM |
163 | [Bodo Moeller] |
164 | ||
6951c23a RL |
165 | *) Add processing of proxy certificates (see RFC 3820). This work was |
166 | sponsored by KTH (The Royal Institute of Technology in Stockholm) and | |
167 | EGEE (Enabling Grids for E-science in Europe). | |
168 | [Richard Levitte] | |
169 | ||
ea681ba8 AP |
170 | *) RC4 performance overhaul on modern architectures/implementations, such |
171 | as Intel P4, IA-64 and AMD64. | |
172 | [Andy Polyakov] | |
173 | ||
401ee37a DSH |
174 | *) New utility extract-section.pl. This can be used specify an alternative |
175 | section number in a pod file instead of having to treat each file as | |
176 | a separate case in Makefile. This can be done by adding two lines to the | |
177 | pod file: | |
178 | ||
179 | =for comment openssl_section:XXX | |
180 | ||
181 | The blank line is mandatory. | |
182 | ||
183 | [Steve Henson] | |
184 | ||
826a42a0 DSH |
185 | *) New arguments -certform, -keyform and -pass for s_client and s_server |
186 | to allow alternative format key and certificate files and passphrase | |
187 | sources. | |
188 | [Steve Henson] | |
189 | ||
5d7c222d DSH |
190 | *) New structure X509_VERIFY_PARAM which combines current verify parameters, |
191 | update associated structures and add various utility functions. | |
192 | ||
193 | Add new policy related verify parameters, include policy checking in | |
194 | standard verify code. Enhance 'smime' application with extra parameters | |
195 | to support policy checking and print out. | |
196 | [Steve Henson] | |
197 | ||
30fe028f GT |
198 | *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3 |
199 | Nehemiah processors. These extensions support AES encryption in hardware | |
200 | as well as RNG (though RNG support is currently disabled). | |
201 | [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov] | |
202 | ||
df11e1e9 GT |
203 | *) Deprecate BN_[get|set]_params() functions (they were ignored internally). |
204 | [Geoff Thorpe] | |
205 | ||
ad500340 AP |
206 | *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented. |
207 | [Andy Polyakov and a number of other people] | |
208 | ||
e14f4aab AP |
209 | *) Improved PowerPC platform support. Most notably BIGNUM assembler |
210 | implementation contributed by IBM. | |
211 | [Suresh Chari, Peter Waltenberg, Andy Polyakov] | |
212 | ||
bcfea9fb GT |
213 | *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public |
214 | exponent rather than 'unsigned long'. There is a corresponding change to | |
215 | the new 'rsa_keygen' element of the RSA_METHOD structure. | |
216 | [Jelte Jansen, Geoff Thorpe] | |
217 | ||
d5f686d8 BM |
218 | *) Functionality for creating the initial serial number file is now |
219 | moved from CA.pl to the 'ca' utility with a new option -create_serial. | |
220 | ||
221 | (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial | |
222 | number file to 1, which is bound to cause problems. To avoid | |
223 | the problems while respecting compatibility between different 0.9.7 | |
224 | patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in | |
225 | CA.pl for serial number initialization. With the new release 0.9.8, | |
226 | we can fix the problem directly in the 'ca' utility.) | |
64674bcc DSH |
227 | [Steve Henson] |
228 | ||
3a87a9b9 GT |
229 | *) Reduced header interdepencies by declaring more opaque objects in |
230 | ossl_typ.h. As a consequence, including some headers (eg. engine.h) will | |
231 | give fewer recursive includes, which could break lazy source code - so | |
232 | this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always, | |
233 | developers should define this symbol when building and using openssl to | |
234 | ensure they track the recommended behaviour, interfaces, [etc], but | |
235 | backwards-compatible behaviour prevails when this isn't defined. | |
236 | [Geoff Thorpe] | |
237 | ||
bf5773fa DSH |
238 | *) New function X509_POLICY_NODE_print() which prints out policy nodes. |
239 | [Steve Henson] | |
240 | ||
216659eb DSH |
241 | *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality. |
242 | This will generate a random key of the appropriate length based on the | |
243 | cipher context. The EVP_CIPHER can provide its own random key generation | |
244 | routine to support keys of a specific form. This is used in the des and | |
245 | 3des routines to generate a key of the correct parity. Update S/MIME | |
246 | code to use new functions and hence generate correct parity DES keys. | |
247 | Add EVP_CHECK_DES_KEY #define to return an error if the key is not | |
248 | valid (weak or incorrect parity). | |
249 | [Steve Henson] | |
250 | ||
e1a27eb3 DSH |
251 | *) Add a local set of CRLs that can be used by X509_verify_cert() as well |
252 | as looking them up. This is useful when the verified structure may contain | |
253 | CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs | |
254 | present unless the new PKCS7_NO_CRL flag is asserted. | |
255 | [Steve Henson] | |
256 | ||
6446e0c3 DSH |
257 | *) Extend ASN1 oid configuration module. It now additionally accepts the |
258 | syntax: | |
259 | ||
260 | shortName = some long name, 1.2.3.4 | |
261 | [Steve Henson] | |
262 | ||
5c98b2ca GT |
263 | *) Reimplemented the BN_CTX implementation. There is now no more static |
264 | limitation on the number of variables it can handle nor the depth of the | |
265 | "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack | |
266 | information can now expand as required, and rather than having a single | |
267 | static array of bignums, BN_CTX now uses a linked-list of such arrays | |
268 | allowing it to expand on demand whilst maintaining the usefulness of | |
269 | BN_CTX's "bundling". | |
270 | [Geoff Thorpe] | |
271 | ||
46ef873f GT |
272 | *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD |
273 | to allow all RSA operations to function using a single BN_CTX. | |
274 | [Geoff Thorpe] | |
275 | ||
4acc3e90 DSH |
276 | *) Preliminary support for certificate policy evaluation and checking. This |
277 | is initially intended to pass the tests outlined in "Conformance Testing | |
278 | of Relying Party Client Certificate Path Processing Logic" v1.07. | |
279 | [Steve Henson] | |
280 | ||
7f663ce4 GT |
281 | *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and |
282 | remained unused and not that useful. A variety of other little bignum | |
283 | tweaks and fixes have also been made continuing on from the audit (see | |
284 | below). | |
285 | [Geoff Thorpe] | |
286 | ||
875a644a RL |
287 | *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with |
288 | associated ASN1, EVP and SSL functions and old ASN1 macros. | |
7f663ce4 | 289 | [Richard Levitte] |
875a644a | 290 | |
b6358c89 GT |
291 | *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results, |
292 | and this should never fail. So the return value from the use of | |
293 | BN_set_word() (which can fail due to needless expansion) is now deprecated; | |
294 | if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro. | |
295 | [Geoff Thorpe] | |
296 | ||
9e051bac GT |
297 | *) BN_CTX_get() should return zero-valued bignums, providing the same |
298 | initialised value as BN_new(). | |
299 |
