bf3d6c0c | 5 | Changes between 0.9.8a and 0.9.9 [xx XXX xxxx] |
28e4fe34 | 6 | |
eea374fd DSH |
7 | *) Support for PKCS#1 RSAPublicKey format on rsa utility command line. |
8 | [Steve Henson] | |
9 | ||
45e27385 DSH |
10 | *) Remove the ancient ASN1_METHOD code. This was only ever used in one |
11 | place for the (very old) "NETSCAPE" format certificates which are now | |
12 | handled using new ASN1 code equivalents. | |
eea374fd | 13 | [Steve Henson] |
45e27385 | 14 | |
4ebb342f NL |
15 | *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD |
16 | pointer and make the SSL_METHOD parameter in SSL_CTX_new, | |
17 | SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'. | |
18 | [Nils Larsch] | |
19 | ||
9aa9d70d | 20 | *) Modify CRL distribution points extension code to print out previously |
0745d089 DSH |
21 | unsupported fields. Enhance extension setting code to allow setting of |
22 | all fields. | |
9aa9d70d DSH |
23 | [Steve Henson] |
24 | ||
0537f968 | 25 | *) Add print and set support for Issuing Distribution Point CRL extension. |
231493c9 | 26 | [Steve Henson] |
28e4fe34 | 27 | |
2bd2cd9b RL |
28 | Changes between 0.9.8 and 0.9.8a [XX xxx XXXX] |
29 | ||
770bc596 | 30 | *) Avoid some small subgroup attacks in Diffie-Hellman. |
bf3d6c0c BL |
31 | [Nick Mathewson and Ben Laurie] |
32 | ||
33 | *) Add functions for well-known primes. | |
34 | [Nick Mathewson] | |
35 | ||
0491e058 AP |
36 | *) Extended Windows CE support. |
37 | [Satoshi Nakamura and Andy Polyakov] | |
38 | ||
f3b656b2 DSH |
39 | *) Initialize SSL_METHOD structures at compile time instead of during |
40 | runtime, thus removing the need for a lock. | |
41 | [Steve Henson] | |
42 | ||
8f2e4fdf DSH |
43 | *) Make PKCS7_decrypt() work even if no certificate is supplied by |
44 | attempting to decrypt each encrypted key in turn. Add support to | |
45 | smime utility. | |
46 | [Steve Henson] | |
2bd2cd9b RL |
47 | |
48 | Changes between 0.9.7h and 0.9.8 [05 Jul 2005] | |
12bdb643 | 49 | |
c8310124 RL |
50 | *) Add libcrypto.pc and libssl.pc for those who feel they need them. |
51 | [Richard Levitte] | |
52 | ||
53 | *) Change CA.sh and CA.pl so they don't bundle the CSR and the private | |
54 | key into the same file any more. | |
55 | [Richard Levitte] | |
56 | ||
8d3509b9 AP |
57 | *) Add initial support for Win64, both IA64 and AMD64/x64 flavors. |
58 | [Andy Polyakov] | |
59 | ||
cbdac46d DSH |
60 | *) Add -utf8 command line and config file option to 'ca'. |
61 | [Stefan <stf@udoma.org] | |
62 | ||
c8310124 RL |
63 | *) Removed the macro des_crypt(), as it seems to conflict with some |
64 | libraries. Use DES_crypt(). | |
65 | [Richard Levitte] | |
66 | ||
a2c32e2d GT |
67 | *) Correct naming of the 'chil' and '4758cca' ENGINEs. This |
68 | involves renaming the source and generated shared-libs for | |
69 | both. The engines will accept the corrected or legacy ids | |
70 | ('ncipher' and '4758_cca' respectively) when binding. NB, | |
71 | this only applies when building 'shared'. | |
72 | [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe] | |
73 | ||
b6995add DSH |
74 | *) Add attribute functions to EVP_PKEY structure. Modify |
75 | PKCS12_create() to recognize a CSP name attribute and | |
76 | use it. Make -CSP option work again in pkcs12 utility. | |
77 | [Steve Henson] | |
78 | ||
800e400d NL |
79 | *) Add new functionality to the bn blinding code: |
80 | - automatic re-creation of the BN_BLINDING parameters after | |
81 | a fixed number of uses (currently 32) | |
82 | - add new function for parameter creation | |
83 | - introduce flags to control the update behaviour of the | |
84 | BN_BLINDING parameters | |
85 | - hide BN_BLINDING structure | |
86 | Add a second BN_BLINDING slot to the RSA structure to improve | |
87 | performance when a single RSA object is shared among several | |
88 | threads. | |
89 | [Nils Larsch] | |
90 | ||
36d16f8e BL |
91 | *) Add support for DTLS. |
92 | [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie] | |
93 | ||
dc0ed30c NL |
94 | *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1) |
95 | to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file() | |
96 | [Walter Goulet] | |
97 | ||
6049399b NL |
98 | *) Remove buggy and incompletet DH cert support from |
99 | ssl/ssl_rsa.c and ssl/s3_both.c | |
100 | [Nils Larsch] | |
101 | ||
12bdb643 NL |
102 | *) Use SHA-1 instead of MD5 as the default digest algorithm for |
103 | the apps/openssl applications. | |
104 | [Nils Larsch] | |
4d94ae00 | 105 | |
41a15c4f BL |
106 | *) Compile clean with "-Wall -Wmissing-prototypes |
107 | -Wstrict-prototypes -Wmissing-declarations -Werror". Currently | |
108 | DEBUG_SAFESTACK must also be set. | |
109 | [Ben Laurie] | |
110 | ||
c9a112f5 | 111 | *) Change ./Configure so that certain algorithms can be disabled by default. |
ecc5ef87 BM |
112 | The new counterpiece to "no-xxx" is "enable-xxx". |
113 | ||
114 | The patented RC5 and MDC2 algorithms will now be disabled unless | |
115 | "enable-rc5" and "enable-mdc2", respectively, are specified. | |
116 | ||
117 | (IDEA remains enabled despite being patented. This is because IDEA | |
118 | is frequently required for interoperability, and there is no license | |
119 | fee for non-commercial use. As before, "no-idea" can be used to | |
120 | avoid this algorithm.) | |
121 | ||
c9a112f5 BM |
122 | [Bodo Moeller] |
123 | ||
6951c23a RL |
124 | *) Add processing of proxy certificates (see RFC 3820). This work was |
125 | sponsored by KTH (The Royal Institute of Technology in Stockholm) and | |
126 | EGEE (Enabling Grids for E-science in Europe). | |
127 | [Richard Levitte] | |
128 | ||
ea681ba8 AP |
129 | *) RC4 performance overhaul on modern architectures/implementations, such |
130 | as Intel P4, IA-64 and AMD64. | |
131 | [Andy Polyakov] | |
132 | ||
401ee37a DSH |
133 | *) New utility extract-section.pl. This can be used specify an alternative |
134 | section number in a pod file instead of having to treat each file as | |
135 | a separate case in Makefile. This can be done by adding two lines to the | |
136 | pod file: | |
137 | ||
138 | =for comment openssl_section:XXX | |
139 | ||
140 | The blank line is mandatory. | |
141 | ||
142 | [Steve Henson] | |
143 | ||
826a42a0 DSH |
144 | *) New arguments -certform, -keyform and -pass for s_client and s_server |
145 | to allow alternative format key and certificate files and passphrase | |
146 | sources. | |
147 | [Steve Henson] | |
148 | ||
5d7c222d DSH |
149 | *) New structure X509_VERIFY_PARAM which combines current verify parameters, |
150 | update associated structures and add various utility functions. | |
151 | ||
152 | Add new policy related verify parameters, include policy checking in | |
153 | standard verify code. Enhance 'smime' application with extra parameters | |
154 | to support policy checking and print out. | |
155 | [Steve Henson] | |
156 | ||
30fe028f GT |
157 | *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3 |
158 | Nehemiah processors. These extensions support AES encryption in hardware | |
159 | as well as RNG (though RNG support is currently disabled). | |
160 | [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov] | |
161 | ||
df11e1e9 GT |
162 | *) Deprecate BN_[get|set]_params() functions (they were ignored internally). |
163 | [Geoff Thorpe] | |
164 | ||
ad500340 AP |
165 | *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented. |
166 | [Andy Polyakov and a number of other people] | |
167 | ||
e14f4aab AP |
168 | *) Improved PowerPC platform support. Most notably BIGNUM assembler |
169 | implementation contributed by IBM. | |
170 | [Suresh Chari, Peter Waltenberg, Andy Polyakov] | |
171 | ||
bcfea9fb GT |
172 | *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public |
173 | exponent rather than 'unsigned long'. There is a corresponding change to | |
174 | the new 'rsa_keygen' element of the RSA_METHOD structure. | |
175 | [Jelte Jansen, Geoff Thorpe] | |
176 | ||
d5f686d8 BM |
177 | *) Functionality for creating the initial serial number file is now |
178 | moved from CA.pl to the 'ca' utility with a new option -create_serial. | |
179 | ||
180 | (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial | |
181 | number file to 1, which is bound to cause problems. To avoid | |
182 | the problems while respecting compatibility between different 0.9.7 | |
183 | patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in | |
184 | CA.pl for serial number initialization. With the new release 0.9.8, | |
185 | we can fix the problem directly in the 'ca' utility.) | |
64674bcc DSH |
186 | [Steve Henson] |
187 | ||
3a87a9b9 GT |
188 | *) Reduced header interdepencies by declaring more opaque objects in |
189 | ossl_typ.h. As a consequence, including some headers (eg. engine.h) will | |
190 | give fewer recursive includes, which could break lazy source code - so | |
191 | this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always, | |
192 | developers should define this symbol when building and using openssl to | |
193 | ensure they track the recommended behaviour, interfaces, [etc], but | |
194 | backwards-compatible behaviour prevails when this isn't defined. | |
195 | [Geoff Thorpe] | |
196 | ||
bf5773fa DSH |
197 | *) New function X509_POLICY_NODE_print() which prints out policy nodes. |
198 | [Steve Henson] | |
199 | ||
216659eb DSH |
200 | *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality. |
201 | This will generate a random key of the appropriate length based on the | |
202 | cipher context. The EVP_CIPHER can provide its own random key generation | |
203 | routine to support keys of a specific form. This is used in the des and | |
204 | 3des routines to generate a key of the correct parity. Update S/MIME | |
205 | code to use new functions and hence generate correct parity DES keys. | |
206 | Add EVP_CHECK_DES_KEY #define to return an error if the key is not | |
207 | valid (weak or incorrect parity). | |
208 | [Steve Henson] | |
209 | ||
e1a27eb3 DSH |
210 | *) Add a local set of CRLs that can be used by X509_verify_cert() as well |
211 | as looking them up. This is useful when the verified structure may contain | |
212 | CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs | |
213 | present unless the new PKCS7_NO_CRL flag is asserted. | |
214 | [Steve Henson] | |
215 | ||
6446e0c3 DSH |
216 | *) Extend ASN1 oid configuration module. It now additionally accepts the |
217 | syntax: | |
218 | ||
219 | shortName = some long name, 1.2.3.4 | |
220 | [Steve Henson] | |
221 | ||
5c98b2ca GT |
222 | *) Reimplemented the BN_CTX implementation. There is now no more static |
223 | limitation on the number of variables it can handle nor the depth of the | |
224 | "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack | |
225 | information can now expand as required, and rather than having a single | |
226 | static array of bignums, BN_CTX now uses a linked-list of such arrays | |
227 | allowing it to expand on demand whilst maintaining the usefulness of | |
228 | BN_CTX's "bundling". | |
229 | [Geoff Thorpe] | |
230 | ||
46ef873f GT |
231 | *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD |
232 | to allow all RSA operations to function using a single BN_CTX. | |
233 | [Geoff Thorpe] | |
234 | ||
4acc3e90 DSH |
235 | *) Preliminary support for certificate policy evaluation and checking. This |
236 | is initially intended to pass the tests outlined in "Conformance Testing | |
237 | of Relying Party Client Certificate Path Processing Logic" v1.07. | |
238 | [Steve Henson] | |
239 | ||
7f663ce4 GT |
240 | *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and |
241 | remained unused and not that useful. A variety of other little bignum | |
242 | tweaks and fixes have also been made continuing on from the audit (see | |
243 | below). | |
244 | [Geoff Thorpe] | |
245 | ||
875a644a RL |
246 | *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with |
247 | associated ASN1, EVP and SSL functions and old ASN1 macros. | |
7f663ce4 | 248 | [Richard Levitte] |
875a644a | 249 | |
b6358c89 GT |
250 | *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results, |
251 | and this should never fail. So the return value from the use of | |
252 | BN_set_word() (which can fail due to needless expansion) is now deprecated; | |
253 | if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro. | |
254 | [Geoff Thorpe] | |
255 | ||
9e051bac GT |
256 | *) BN_CTX_get() should return zero-valued bignums, providing the same |
257 | initialised value as BN_new(). | |
258 |
