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