7d3ba88a | 5 | Changes between 1.0.2 and 1.1.0 [xx XXX xxxx] |
785da0e6 | 6 | |
5e3ff62c DSH |
7 | *) Experimental encrypt-then-mac support. |
8 | ||
9 | Experimental support for encrypt then mac from | |
10 | draft-gutmann-tls-encrypt-then-mac-02.txt | |
a6e7d1c0 | 11 | |
5e3ff62c DSH |
12 | To enable it set the appropriate extension number (0x10 for the test |
13 | server) using e.g. -DTLSEXT_TYPE_encrypt_then_mac=0x10 | |
a6e7d1c0 | 14 | |
5e3ff62c DSH |
15 | For non-compliant peers (i.e. just about everything) this should have no |
16 | effect. | |
17 | ||
18 | WARNING: EXPERIMENTAL, SUBJECT TO CHANGE. | |
a6e7d1c0 DSH |
19 | |
20 | NOTE: unfortunately the test server value (0x10) clashes with the draft | |
21 | ALPN extension. Until this is resolved the only way to check against the | |
22 | test server is to temporarily change the ALPN extension value (ugh!). | |
23 | ||
5e3ff62c DSH |
24 | [Steve Henson] |
25 | ||
36086186 SD |
26 | *) Add callbacks supporting generation and retrieval of supplemental |
27 | data entries. | |
28 | [Scott Deboy <sdeboy@apache.org>, Trevor Perrin and Ben Laurie] | |
29 | ||
97cf1f6c DSH |
30 | *) Add EVP support for key wrapping algorithms, to avoid problems with |
31 | existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in | |
32 | the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap | |
33 | algorithms and include tests cases. | |
34 | [Steve Henson] | |
35 | ||
5c84d2f5 DSH |
36 | *) Extend CMS code to support RSA-PSS signatures and RSA-OAEP for |
37 | enveloped data. | |
38 | [Steve Henson] | |
39 | ||
271fef0e DSH |
40 | *) Extended RSA OAEP support via EVP_PKEY API. Options to specify digest, |
41 | MGF1 digest and OAEP label. | |
42 | [Steve Henson] | |
43 | ||
c6913eeb DSH |
44 | *) Support for DTLS 1.2. This adds two sets of DTLS methods: DTLS_*_method() |
45 | supports both DTLS 1.2 and 1.0 and should use whatever version the peer | |
46 | supports and DTLSv1_2_*_method() which supports DTLS 1.2 only. | |
47 | [Steve Henson] | |
48 | ||
fefc111a BL |
49 | *) Make openssl verify return errors. |
50 | [Chris Palmer <palmer@google.com> and Ben Laurie] | |
51 | ||
1c455bc0 DSH |
52 | *) New function ASN1_TIME_diff to calculate the difference between two |
53 | ASN1_TIME structures or one structure and the current time. | |
54 | [Steve Henson] | |
55 | ||
a98b8ce6 DSH |
56 | *) Update fips_test_suite to support multiple command line options. New |
57 | test to induce all self test errors in sequence and check expected | |
58 | failures. | |
59 | [Steve Henson] | |
60 | ||
f4324e51 DSH |
61 | *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and |
62 | sign or verify all in one operation. | |
63 | [Steve Henson] | |
64 | ||
3ec9dceb DSH |
65 | *) Add fips_algvs: a multicall fips utility incorporaing all the algorithm |
66 | test programs and fips_test_suite. Includes functionality to parse | |
67 | the minimal script output of fipsalgest.pl directly. | |
f4324e51 | 68 | [Steve Henson] |
3ec9dceb | 69 | |
5e4eb995 DSH |
70 | *) Add authorisation parameter to FIPS_module_mode_set(). |
71 | [Steve Henson] | |
72 | ||
2bfeb7dc DSH |
73 | *) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves. |
74 | [Steve Henson] | |
75 | ||
4420b3b1 | 76 | *) Use separate DRBG fields for internal and external flags. New function |
cb71870d DSH |
77 | FIPS_drbg_health_check() to perform on demand health checking. Add |
78 | generation tests to fips_test_suite with reduced health check interval to | |
4420b3b1 DSH |
79 | demonstrate periodic health checking. Add "nodh" option to |
80 | fips_test_suite to skip very slow DH test. | |
81 | [Steve Henson] | |
82 | ||
15094852 DSH |
83 | *) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers |
84 | based on NID. | |
85 | [Steve Henson] | |
86 | ||
a11f06b2 DSH |
87 | *) More extensive health check for DRBG checking many more failure modes. |
88 | New function FIPS_selftest_drbg_all() to handle every possible DRBG | |
89 | combination: call this in fips_test_suite. | |
90 | [Steve Henson] | |
91 | ||
7fdcb457 DSH |
92 | *) Add support for Dual EC DRBG from SP800-90. Update DRBG algorithm test |
93 | and POST to handle Dual EC cases. | |
94 | [Steve Henson] | |
95 | ||
f55f5f77 DSH |
96 | *) Add support for canonical generation of DSA parameter 'g'. See |
97 | FIPS 186-3 A.2.3. | |
98 | ||
7fdcb457 DSH |
99 | *) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and |
100 | POST to handle HMAC cases. | |
20f12e63 DSH |
101 | [Steve Henson] |
102 | ||
01a9a759 | 103 | *) Add functions FIPS_module_version() and FIPS_module_version_text() |
3d7bf77f | 104 | to return numerical and string versions of the FIPS module number. |
01a9a759 DSH |
105 | [Steve Henson] |
106 | ||
c2fd5989 | 107 | *) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and |
3d7bf77f | 108 | FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implemented |
c2fd5989 DSH |
109 | outside the validated module in the FIPS capable OpenSSL. |
110 | [Steve Henson] | |
111 | ||
e0d1a2f8 | 112 | *) Minor change to DRBG entropy callback semantics. In some cases |
3d7bf77f | 113 | there is no multiple of the block length between min_len and |
e0d1a2f8 DSH |
114 | max_len. Allow the callback to return more than max_len bytes |
115 | of entropy but discard any extra: it is the callback's responsibility | |
116 | to ensure that the extra data discarded does not impact the | |
117 | requested amount of entropy. | |
118 | [Steve Henson] | |
119 | ||
cac4fb58 DSH |
120 | *) Add PRNG security strength checks to RSA, DSA and ECDSA using |
121 | information in FIPS186-3, SP800-57 and SP800-131A. | |
122 | [Steve Henson] | |
123 | ||
b5dd1787 DSH |
124 | *) CCM support via EVP. Interface is very similar to GCM case except we |
125 | must supply all data in one chunk (i.e. no update, final) and the | |
126 | message length must be supplied if AAD is used. Add algorithm test | |
127 | support. | |
23916810 DSH |
128 | [Steve Henson] |
129 | ||
ac892b7a DSH |
130 | *) Initial version of POST overhaul. Add POST callback to allow the status |
131 | of POST to be monitored and/or failures induced. Modify fips_test_suite | |
132 | to use callback. Always run all selftests even if one fails. | |
133 | [Steve Henson] | |
134 | ||
06b7e5a0 DSH |
135 | *) XTS support including algorithm test driver in the fips_gcmtest program. |
136 | Note: this does increase the maximum key length from 32 to 64 bytes but | |
137 | there should be no binary compatibility issues as existing applications | |
138 | will never use XTS mode. | |
32a2d8dd DSH |
139 | [Steve Henson] |
140 | ||
05e24c87 DSH |
141 | *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies |
142 | to OpenSSL RAND code and replace with a tiny FIPS RAND API which also | |
143 | performs algorithm blocking for unapproved PRNG types. Also do not | |
144 | set PRNG type in FIPS_mode_set(): leave this to the application. | |
145 | Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with | |
d7a3ce98 | 146 | the standard OpenSSL PRNG: set additional data to a date time vector. |
05e24c87 DSH |
147 | [Steve Henson] |
148 | ||
cab0595c DSH |
149 | *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*. |
150 | This shouldn't present any incompatibility problems because applications | |
151 | shouldn't be using these directly and any that are will need to rethink | |
152 | anyway as the X9.31 PRNG is now deprecated by FIPS 140-2 | |
153 | [Steve Henson] | |
154 | ||
96ec46f7 DSH |
155 | *) Extensive self tests and health checking required by SP800-90 DRBG. |
156 | Remove strength parameter from FIPS_drbg_instantiate and always | |
157 | instantiate at maximum supported strength. | |
158 | [Steve Henson] | |
159 | ||
8857b380 DSH |
160 | *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing. |
161 | [Steve Henson] | |
162 | ||
11e80de3 DSH |
163 | *) New algorithm test program fips_dhvs to handle DH primitives only testing. |
164 | [Steve Henson] | |
165 | ||
166 | *) New function DH_compute_key_padded() to compute a DH key and pad with | |
167 | leading zeroes if needed: this complies with SP800-56A et al. | |
168 | [Steve Henson] | |
169 | ||
591cbfae DSH |
170 | *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by |
171 | anything, incomplete, subject to change and largely untested at present. | |
172 | [Steve Henson] | |
173 | ||
eead69f5 DSH |
174 | *) Modify fipscanisteronly build option to only build the necessary object |
175 | files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile. | |
176 | [Steve Henson] | |
177 | ||
017bc57b DSH |
178 | *) Add experimental option FIPSSYMS to give all symbols in |
179 | fipscanister.o and FIPS or fips prefix. This will avoid | |
5d439d69 DSH |
180 | conflicts with future versions of OpenSSL. Add perl script |
181 | util/fipsas.pl to preprocess assembly language source files | |
182 | and rename any affected symbols. | |
017bc57b DSH |
183 | [Steve Henson] |
184 | ||
25c65429 DSH |
185 | *) Add selftest checks and algorithm block of non-fips algorithms in |
186 | FIPS mode. Remove DES2 from selftests. | |
187 | [Steve Henson] | |
188 | ||
fe26d066 DSH |
189 | *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just |
190 | return internal method without any ENGINE dependencies. Add new | |
25c65429 | 191 | tiny fips sign and verify functions. |
fe26d066 DSH |
192 | [Steve Henson] |
193 | ||
b3310161 DSH |
194 | *) New build option no-ec2m to disable characteristic 2 code. |
195 | [Steve Henson] | |
196 | ||
30b56225 DSH |
197 | *) New build option "fipscanisteronly". This only builds fipscanister.o |
198 | and (currently) associated fips utilities. Uses the file Makefile.fips | |
199 | instead of Makefile.org as the prototype. | |
200 | [Steve Henson] | |
201 | ||
b3d8022e DSH |
202 | *) Add some FIPS mode restrictions to GCM. Add internal IV generator. |
203 | Update fips_gcmtest to use IV generator. | |
204 | [Steve Henson] | |
205 | ||
bdaa5415 DSH |
206 | *) Initial, experimental EVP support for AES-GCM. AAD can be input by |
207 | setting output buffer to NULL. The *Final function must be | |
208 | called although it will not retrieve any additional data. The tag | |
209 | can be set or retrieved with a ctrl. The IV length is by default 12 | |
210 | bytes (96 bits) but can be set to an alternative value. If the IV | |
211 | length exceeds the maximum IV length (currently 16 bytes) it cannot be | |
212 | set before the key. | |
213 | [Steve Henson] | |
214 | ||
3da0ca79 DSH |
215 | *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the |
216 | underlying do_cipher function handles all cipher semantics itself | |
217 | including padding and finalisation. This is useful if (for example) | |
218 | an ENGINE cipher handles block padding itself. The behaviour of | |
219 | do_cipher is subtly changed if this flag is set: the return value | |
220 | is the number of characters written to the output buffer (zero is | |
221 | no longer an error code) or a negative error code. Also if the | |
d45087c6 | 222 | input buffer is NULL and length 0 finalisation should be performed. |
3da0ca79 DSH |
223 | [Steve Henson] |
224 | ||
2b3936e8 DSH |
225 | *) If a candidate issuer certificate is already part of the constructed |
226 | path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case. | |
227 | [Steve Henson] | |
228 | ||
7c2d4fee BM |
229 | *) Improve forward-security support: add functions |
230 | ||
231 | void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure)) | |
232 | void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure)) | |
233 | ||
234 | for use by SSL/TLS servers; the callback function will be called whenever a | |
235 | new session is created, and gets to decide whether the session may be | |
236 | cached to make it resumable (return 0) or not (return 1). (As by the | |
237 | SSL/TLS protocol specifications, the session_id sent by the server will be | |
238 | empty to indicate that the session is not resumable; also, the server will | |
239 | not generate RFC 4507 (RFC 5077) session tickets.) | |
240 | ||
241 | A simple reasonable callback implementation is to return is_forward_secure. | |
242 | This parameter will be set to 1 or 0 depending on the ciphersuite selected | |
243 | by the SSL/TLS server library, indicating whether it can provide forward | |
244 | security. | |
245 |
