399a6f0b DSH |
5 | Changes between 0.9.8b and 0.9.9 [xx XXX xxxx] |
6 | ||
c4e7870a BM |
7 | *) Change the array representation of binary polynomials: the list |
8 | of degrees of non-zero coefficients is now terminated with -1. | |
9 | Previously it was terminated with 0, which was also part of the | |
10 | value; thus, the array representation was not applicable to | |
11 | polynomials where t^0 has coefficient zero. This change makes | |
12 | the array representation useful in a more general context. | |
13 | [Douglas Stebila] | |
14 | ||
89bbe14c BM |
15 | *) Various modifications and fixes to SSL/TLS cipher string |
16 | handling. For ECC, the code now distinguishes between fixed ECDH | |
17 | with RSA certificates on the one hand and with ECDSA certificates | |
18 | on the other hand, since these are separate ciphersuites. The | |
19 | unused code for Fortezza ciphersuites has been removed. | |
20 | ||
21 | For consistency with EDH, ephemeral ECDH is now called "EECDH" | |
22 | (not "ECDHE"). For consistency with the code for DH | |
23 | certificates, use of ECDH certificates is now considered ECDH | |
24 | authentication, not RSA or ECDSA authentication (the latter is | |
25 | merely the CA's signing algorithm and not actively used in the | |
26 | protocol). | |
27 | ||
28 | The temporary ciphersuite alias "ECCdraft" is no longer | |
29 | available, and ECC ciphersuites are no longer excluded from "ALL" | |
30 | and "DEFAULT". The following aliases now exist for RFC 4492 | |
31 | ciphersuites, most of these by analogy with the DH case: | |
32 | ||
33 | kECDHr - ECDH cert, signed with RSA | |
34 | kECDHe - ECDH cert, signed with ECDSA | |
35 | kECDH - ECDH cert (signed with either RSA or ECDSA) | |
36 | kEECDH - ephemeral ECDH | |
37 | ECDH - ECDH cert or ephemeral ECDH | |
38 | ||
39 | aECDH - ECDH cert | |
40 | aECDSA - ECDSA cert | |
41 | ECDSA - ECDSA cert | |
42 | ||
43 | AECDH - anonymous ECDH | |
44 | EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH") | |
45 | ||
46 | [Bodo Moeller] | |
47 | ||
fb7b3932 DSH |
48 | *) Add additional S/MIME capabilities for AES and GOST ciphers if supported. |
49 | Use correct micalg parameters depending on digest(s) in signed message. | |
50 | [Steve Henson] | |
51 | ||
01b8b3c7 DSH |
52 | *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process |
53 | an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code. | |
54 | [Steve Henson] | |
de9fcfe3 | 55 | |
58aa573a | 56 | *) Initial engine support for EVP_PKEY_METHOD. New functions to permit |
c9777d26 DSH |
57 | an engine to register a method. Add ENGINE lookups for methods and |
58 | functional reference processing. | |
58aa573a DSH |
59 | [Steve Henson] |
60 | ||
91c9e621 DSH |
61 | *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of |
62 | EVP_{Sign,Verify}* which allow an application to customise the signature | |
63 | process. | |
64 | [Steve Henson] | |
65 | ||
55311921 DSH |
66 | *) New -resign option to smime utility. This adds one or more signers |
67 | to an existing PKCS#7 signedData structure. Also -md option to use an | |
68 | alternative message digest algorithm for signing. | |
69 | [Steve Henson] | |
70 | ||
a6e7fcd1 DSH |
71 | *) Tidy up PKCS#7 routines and add new functions to make it easier to |
72 | create PKCS7 structures containing multiple signers. Update smime | |
73 | application to support multiple signers. | |
74 | [Steve Henson] | |
75 | ||
121dd39f DSH |
76 | *) New -macalg option to pkcs12 utility to allow setting of an alternative |
77 | digest MAC. | |
78 | [Steve Henson] | |
79 | ||
856640b5 | 80 | *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC. |
b8f702a0 | 81 | Reorganize PBE internals to lookup from a static table using NIDs, |
6d3a1eac DSH |
82 | add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl: |
83 | EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative | |
84 | PRF which will be automatically used with PBES2. | |
856640b5 DSH |
85 | [Steve Henson] |
86 | ||
34b3c72e | 87 | *) Replace the algorithm specific calls to generate keys in "req" with the |
959e8dfe DSH |
88 | new API. |
89 | [Steve Henson] | |
90 | ||
399a6f0b DSH |
91 | *) Update PKCS#7 enveloped data routines to use new API. This is now |
92 | supported by any public key method supporting the encrypt operation. A | |
93 | ctrl is added to allow the public key algorithm to examine or modify | |
94 | the PKCS#7 RecipientInfo structure if it needs to: for RSA this is | |
95 | a no op. | |
96 | [Steve Henson] | |
28e4fe34 | 97 | |
03919683 DSH |
98 | *) Add a ctrl to asn1 method to allow a public key algorithm to express |
99 | a default digest type to use. In most cases this will be SHA1 but some | |
100 | algorithms (such as GOST) need to specify an alternative digest. The | |
101 | return value indicates how strong the prefernce is 1 means optional and | |
102 | 2 is mandatory (that is it is the only supported type). Modify | |
103 | ASN1_item_sign() to accept a NULL digest argument to indicate it should | |
104 | use the default md. Update openssl utilities to use the default digest | |
105 | type for signing if it is not explicitly indicated. | |
106 | [Steve Henson] | |
107 | ||
ee1d9ec0 DSH |
108 | *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New |
109 | EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant | |
110 | signing method from the key type. This effectively removes the link | |
111 | between digests and public key types. | |
112 | [Steve Henson] | |
113 | ||
d2027098 DSH |
114 | *) Add an OID cross reference table and utility functions. Its purpose is to |
115 | translate between signature OIDs such as SHA1WithrsaEncryption and SHA1, | |
116 | rsaEncryption. This will allow some of the algorithm specific hackery | |
117 | needed to use the correct OID to be removed. | |
118 | [Steve Henson] | |
119 | ||
492a9e24 DSH |
120 | *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO |
121 | structures for PKCS7_sign(). They are now set up by the relevant public | |
122 | key ASN1 method. | |
123 | [Steve Henson] | |
124 | ||
9ca7047d DSH |
125 | *) Add provisional EC pkey method with support for ECDSA and ECDH. |
126 | [Steve Henson] | |
127 | ||
ffb1ac67 DSH |
128 | *) Add support for key derivation (agreement) in the API, DH method and |
129 | pkeyutl. | |
130 | [Steve Henson] | |
131 | ||
3ba0885a DSH |
132 | *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support |
133 | public and private key formats. As a side effect these add additional | |
134 | command line functionality not previously available: DSA signatures can be | |
135 | generated and verified using pkeyutl and DH key support and generation in | |
136 | pkey, genpkey. | |
137 | [Steve Henson] | |
138 | ||
4700aea9 UM |
139 | *) BeOS support. |
140 | [Oliver Tappe <zooey@hirschkaefer.de>] | |
141 | ||
142 | *) New make target "install_html_docs" installs HTML renditions of the | |
143 | manual pages. | |
144 | [Oliver Tappe <zooey@hirschkaefer.de>] | |
145 | ||
f5cda4cb DSH |
146 | *) New utility "genpkey" this is analagous to "genrsa" etc except it can |
147 | generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to | |
148 | support key and parameter generation and add initial key generation | |
149 | functionality for RSA. | |
150 | [Steve Henson] | |
151 | ||
f733a5ef DSH |
152 | *) Add functions for main EVP_PKEY_method operations. The undocumented |
153 | functions EVP_PKEY_{encrypt,decrypt} have been renamed to | |
154 | EVP_PKEY_{encrypt,decrypt}_old. | |
155 | [Steve Henson] | |
156 | ||
0b6f3c66 DSH |
157 | *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public |
158 | key API, doesn't do much yet. | |
159 | [Steve Henson] | |
160 | ||
0b33dac3 DSH |
161 | *) New function EVP_PKEY_asn1_get0_info() to retrieve information about |
162 | public key algorithms. New option to openssl utility: | |
163 | "list-public-key-algorithms" to print out info. | |
164 | [Steve Henson] | |
165 | ||
33273721 BM |
166 | *) Implement the Supported Elliptic Curves Extension for |
167 | ECC ciphersuites from draft-ietf-tls-ecc-12.txt. | |
168 | [Douglas Stebila] | |
169 | ||
246e0931 DSH |
170 | *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or |
171 | EVP_CIPHER structures to avoid later problems in EVP_cleanup(). | |
172 | [Steve Henson] | |
173 | ||
3e4585c8 | 174 | *) New utilities pkey and pkeyparam. These are similar to algorithm specific |
f5cda4cb | 175 | utilities such as rsa, dsa, dsaparam etc except they process any key |
3e4585c8 | 176 | type. |
3e84b6e1 DSH |
177 | [Steve Henson] |
178 | ||
35208f36 DSH |
179 | *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New |
180 | functions EVP_PKEY_print_public(), EVP_PKEY_print_private(), | |
181 | EVP_PKEY_print_param() to print public key data from an EVP_PKEY | |
182 | structure. | |
183 | [Steve Henson] | |
184 | ||
448be743 DSH |
185 | *) Initial support for pluggable public key ASN1. |
186 | De-spaghettify the public key ASN1 handling. Move public and private | |
187 | key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate | |
188 | algorithm specific handling to a single module within the relevant | |
189 | algorithm directory. Add functions to allow (near) opaque processing | |
190 | of public and private key structures. | |
191 | [Steve Henson] | |
192 | ||
36ca4ba6 BM |
193 | *) Implement the Supported Point Formats Extension for |
194 | ECC ciphersuites from draft-ietf-tls-ecc-12.txt. | |
195 | [Douglas Stebila] | |
196 | ||
ddac1974 NL |
197 | *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members |
198 | for the psk identity [hint] and the psk callback functions to the | |
199 | SSL_SESSION, SSL and SSL_CTX structure. | |
200 | ||
201 | New ciphersuites: | |
202 | PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA, | |
203 | PSK-AES256-CBC-SHA | |
204 | ||
205 | New functions: | |
206 | SSL_CTX_use_psk_identity_hint | |
207 | SSL_get_psk_identity_hint | |
208 | SSL_get_psk_identity | |
209 | SSL_use_psk_identity_hint | |
210 | ||
211 | [Mika Kousa and Pasi Eronen of Nokia Corporation] | |
212 | ||
c7235be6 UM |
213 | *) Add RFC 3161 compliant time stamp request creation, response generation |
214 | and response verification functionality. | |
215 |
