7b3a9b00 | 5 | Changes between 1.0.1 and 1.1.0 [xx XXX xxxx] |
aaf35f11 | 6 | |
2ca873e8 DSH |
7 | *) Transparently support X9.42 DH parameters when calling |
8 | PEM_read_bio_DHparameters. This means existing applications can handle | |
9 | the new parameter format automatically. | |
10 | [Steve Henson] | |
11 | ||
afb14cda DSH |
12 | *) Initial experimental support for X9.42 DH parameter format: mainly |
13 | to support use of 'q' parameter for RFC5114 parameters. | |
14 | [Steve Henson] | |
15 | ||
20bee968 DSH |
16 | *) Add DH parameters from RFC5114 including test data to dhtest. |
17 | [Steve Henson] | |
18 | ||
a98b8ce6 DSH |
19 | *) Update fips_test_suite to support multiple command line options. New |
20 | test to induce all self test errors in sequence and check expected | |
21 | failures. | |
22 | [Steve Henson] | |
23 | ||
f4324e51 DSH |
24 | *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and |
25 | sign or verify all in one operation. | |
26 | [Steve Henson] | |
27 | ||
3ec9dceb DSH |
28 | *) Add fips_algvs: a multicall fips utility incorporaing all the algorithm |
29 | test programs and fips_test_suite. Includes functionality to parse | |
30 | the minimal script output of fipsalgest.pl directly. | |
f4324e51 | 31 | [Steve Henson] |
3ec9dceb | 32 | |
5e4eb995 DSH |
33 | *) Add authorisation parameter to FIPS_module_mode_set(). |
34 | [Steve Henson] | |
35 | ||
2bfeb7dc DSH |
36 | *) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves. |
37 | [Steve Henson] | |
38 | ||
4420b3b1 | 39 | *) Use separate DRBG fields for internal and external flags. New function |
cb71870d DSH |
40 | FIPS_drbg_health_check() to perform on demand health checking. Add |
41 | generation tests to fips_test_suite with reduced health check interval to | |
4420b3b1 DSH |
42 | demonstrate periodic health checking. Add "nodh" option to |
43 | fips_test_suite to skip very slow DH test. | |
44 | [Steve Henson] | |
45 | ||
15094852 DSH |
46 | *) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers |
47 | based on NID. | |
48 | [Steve Henson] | |
49 | ||
a11f06b2 DSH |
50 | *) More extensive health check for DRBG checking many more failure modes. |
51 | New function FIPS_selftest_drbg_all() to handle every possible DRBG | |
52 | combination: call this in fips_test_suite. | |
53 | [Steve Henson] | |
54 | ||
7fdcb457 DSH |
55 | *) Add support for Dual EC DRBG from SP800-90. Update DRBG algorithm test |
56 | and POST to handle Dual EC cases. | |
57 | [Steve Henson] | |
58 | ||
f55f5f77 DSH |
59 | *) Add support for canonical generation of DSA parameter 'g'. See |
60 | FIPS 186-3 A.2.3. | |
61 | ||
7fdcb457 DSH |
62 | *) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and |
63 | POST to handle HMAC cases. | |
20f12e63 DSH |
64 | [Steve Henson] |
65 | ||
01a9a759 DSH |
66 | *) Add functions FIPS_module_version() and FIPS_module_version_text() |
67 | to return numberical and string versions of the FIPS module number. | |
68 | [Steve Henson] | |
69 | ||
c2fd5989 DSH |
70 | *) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and |
71 | FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implmeneted | |
72 | outside the validated module in the FIPS capable OpenSSL. | |
73 | [Steve Henson] | |
74 | ||
e0d1a2f8 DSH |
75 | *) Minor change to DRBG entropy callback semantics. In some cases |
76 | there is no mutiple of the block length between min_len and | |
77 | max_len. Allow the callback to return more than max_len bytes | |
78 | of entropy but discard any extra: it is the callback's responsibility | |
79 | to ensure that the extra data discarded does not impact the | |
80 | requested amount of entropy. | |
81 | [Steve Henson] | |
82 | ||
cac4fb58 DSH |
83 | *) Add PRNG security strength checks to RSA, DSA and ECDSA using |
84 | information in FIPS186-3, SP800-57 and SP800-131A. | |
85 | [Steve Henson] | |
86 | ||
b5dd1787 DSH |
87 | *) CCM support via EVP. Interface is very similar to GCM case except we |
88 | must supply all data in one chunk (i.e. no update, final) and the | |
89 | message length must be supplied if AAD is used. Add algorithm test | |
90 | support. | |
23916810 DSH |
91 | [Steve Henson] |
92 | ||
ac892b7a DSH |
93 | *) Initial version of POST overhaul. Add POST callback to allow the status |
94 | of POST to be monitored and/or failures induced. Modify fips_test_suite | |
95 | to use callback. Always run all selftests even if one fails. | |
96 | [Steve Henson] | |
97 | ||
06b7e5a0 DSH |
98 | *) XTS support including algorithm test driver in the fips_gcmtest program. |
99 | Note: this does increase the maximum key length from 32 to 64 bytes but | |
100 | there should be no binary compatibility issues as existing applications | |
101 | will never use XTS mode. | |
32a2d8dd DSH |
102 | [Steve Henson] |
103 | ||
05e24c87 DSH |
104 | *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies |
105 | to OpenSSL RAND code and replace with a tiny FIPS RAND API which also | |
106 | performs algorithm blocking for unapproved PRNG types. Also do not | |
107 | set PRNG type in FIPS_mode_set(): leave this to the application. | |
108 | Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with | |
d7a3ce98 | 109 | the standard OpenSSL PRNG: set additional data to a date time vector. |
05e24c87 DSH |
110 | [Steve Henson] |
111 | ||
cab0595c DSH |
112 | *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*. |
113 | This shouldn't present any incompatibility problems because applications | |
114 | shouldn't be using these directly and any that are will need to rethink | |
115 | anyway as the X9.31 PRNG is now deprecated by FIPS 140-2 | |
116 | [Steve Henson] | |
117 | ||
96ec46f7 DSH |
118 | *) Extensive self tests and health checking required by SP800-90 DRBG. |
119 | Remove strength parameter from FIPS_drbg_instantiate and always | |
120 | instantiate at maximum supported strength. | |
121 | [Steve Henson] | |
122 | ||
8857b380 DSH |
123 | *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing. |
124 | [Steve Henson] | |
125 | ||
11e80de3 DSH |
126 | *) New algorithm test program fips_dhvs to handle DH primitives only testing. |
127 | [Steve Henson] | |
128 | ||
129 | *) New function DH_compute_key_padded() to compute a DH key and pad with | |
130 | leading zeroes if needed: this complies with SP800-56A et al. | |
131 | [Steve Henson] | |
132 | ||
591cbfae DSH |
133 | *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by |
134 | anything, incomplete, subject to change and largely untested at present. | |
135 | [Steve Henson] | |
136 | ||
eead69f5 DSH |
137 | *) Modify fipscanisteronly build option to only build the necessary object |
138 | files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile. | |
139 | [Steve Henson] | |
140 | ||
017bc57b DSH |
141 | *) Add experimental option FIPSSYMS to give all symbols in |
142 | fipscanister.o and FIPS or fips prefix. This will avoid | |
5d439d69 DSH |
143 | conflicts with future versions of OpenSSL. Add perl script |
144 | util/fipsas.pl to preprocess assembly language source files | |
145 | and rename any affected symbols. | |
017bc57b DSH |
146 | [Steve Henson] |
147 | ||
25c65429 DSH |
148 | *) Add selftest checks and algorithm block of non-fips algorithms in |
149 | FIPS mode. Remove DES2 from selftests. | |
150 | [Steve Henson] | |
151 | ||
fe26d066 DSH |
152 | *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just |
153 | return internal method without any ENGINE dependencies. Add new | |
25c65429 | 154 | tiny fips sign and verify functions. |
fe26d066 DSH |
155 | [Steve Henson] |
156 | ||
b3310161 DSH |
157 | *) New build option no-ec2m to disable characteristic 2 code. |
158 | [Steve Henson] | |
159 | ||
30b56225 DSH |
160 | *) New build option "fipscanisteronly". This only builds fipscanister.o |
161 | and (currently) associated fips utilities. Uses the file Makefile.fips | |
162 | instead of Makefile.org as the prototype. | |
163 | [Steve Henson] | |
164 | ||
b3d8022e DSH |
165 | *) Add some FIPS mode restrictions to GCM. Add internal IV generator. |
166 | Update fips_gcmtest to use IV generator. | |
167 | [Steve Henson] | |
168 | ||
bdaa5415 DSH |
169 | *) Initial, experimental EVP support for AES-GCM. AAD can be input by |
170 | setting output buffer to NULL. The *Final function must be | |
171 | called although it will not retrieve any additional data. The tag | |
172 | can be set or retrieved with a ctrl. The IV length is by default 12 | |
173 | bytes (96 bits) but can be set to an alternative value. If the IV | |
174 | length exceeds the maximum IV length (currently 16 bytes) it cannot be | |
175 | set before the key. | |
176 | [Steve Henson] | |
177 | ||
3da0ca79 DSH |
178 | *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the |
179 | underlying do_cipher function handles all cipher semantics itself | |
180 | including padding and finalisation. This is useful if (for example) | |
181 | an ENGINE cipher handles block padding itself. The behaviour of | |
182 | do_cipher is subtly changed if this flag is set: the return value | |
183 | is the number of characters written to the output buffer (zero is | |
184 | no longer an error code) or a negative error code. Also if the | |
d45087c6 | 185 | input buffer is NULL and length 0 finalisation should be performed. |
3da0ca79 DSH |
186 | [Steve Henson] |
187 | ||
2b3936e8 DSH |
188 | *) If a candidate issuer certificate is already part of the constructed |
189 | path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case. | |
190 | [Steve Henson] | |
191 | ||
7c2d4fee BM |
192 | *) Improve forward-security support: add functions |
193 | ||
194 | void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure)) | |
195 | void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure)) | |
196 | ||
197 | for use by SSL/TLS servers; the callback function will be called whenever a | |
198 | new session is created, and gets to decide whether the session may be | |
199 | cached to make it resumable (return 0) or not (return 1). (As by the | |
200 | SSL/TLS protocol specifications, the session_id sent by the server will be | |
201 | empty to indicate that the session is not resumable; also, the server will | |
202 | not generate RFC 4507 (RFC 5077) session tickets.) | |
203 | ||
204 | A simple reasonable callback implementation is to return is_forward_secure. | |
205 | This parameter will be set to 1 or 0 depending on the ciphersuite selected | |
206 | by the SSL/TLS server library, indicating whether it can provide forward | |
207 | security. | |
208 |
