7b3a9b00 | 5 | Changes between 1.0.1 and 1.1.0 [xx XXX xxxx] |
aaf35f11 | 6 | |
23916810 DSH |
7 | *) Initial untested CCM support via EVP. Interface is very similar to GCM |
8 | case except we must supply all data in one chunk (i.e. no update, final) | |
9 | and the message length must be supplied if AAD is used. | |
10 | [Steve Henson] | |
11 | ||
ac892b7a DSH |
12 | *) Initial version of POST overhaul. Add POST callback to allow the status |
13 | of POST to be monitored and/or failures induced. Modify fips_test_suite | |
14 | to use callback. Always run all selftests even if one fails. | |
15 | [Steve Henson] | |
16 | ||
06b7e5a0 DSH |
17 | *) XTS support including algorithm test driver in the fips_gcmtest program. |
18 | Note: this does increase the maximum key length from 32 to 64 bytes but | |
19 | there should be no binary compatibility issues as existing applications | |
20 | will never use XTS mode. | |
32a2d8dd DSH |
21 | [Steve Henson] |
22 | ||
05e24c87 DSH |
23 | *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies |
24 | to OpenSSL RAND code and replace with a tiny FIPS RAND API which also | |
25 | performs algorithm blocking for unapproved PRNG types. Also do not | |
26 | set PRNG type in FIPS_mode_set(): leave this to the application. | |
27 | Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with | |
d7a3ce98 | 28 | the standard OpenSSL PRNG: set additional data to a date time vector. |
05e24c87 DSH |
29 | [Steve Henson] |
30 | ||
cab0595c DSH |
31 | *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*. |
32 | This shouldn't present any incompatibility problems because applications | |
33 | shouldn't be using these directly and any that are will need to rethink | |
34 | anyway as the X9.31 PRNG is now deprecated by FIPS 140-2 | |
35 | [Steve Henson] | |
36 | ||
96ec46f7 DSH |
37 | *) Extensive self tests and health checking required by SP800-90 DRBG. |
38 | Remove strength parameter from FIPS_drbg_instantiate and always | |
39 | instantiate at maximum supported strength. | |
40 | [Steve Henson] | |
41 | ||
0deea0e0 | 42 | *) Add SRP support. |
d4f3dd5f | 43 | [Tom Wu <tjw@cs.stanford.edu> and Ben Laurie] |
0deea0e0 | 44 | |
8857b380 DSH |
45 | *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing. |
46 | [Steve Henson] | |
47 | ||
11e80de3 DSH |
48 | *) New algorithm test program fips_dhvs to handle DH primitives only testing. |
49 | [Steve Henson] | |
50 | ||
51 | *) New function DH_compute_key_padded() to compute a DH key and pad with | |
52 | leading zeroes if needed: this complies with SP800-56A et al. | |
53 | [Steve Henson] | |
54 | ||
591cbfae DSH |
55 | *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by |
56 | anything, incomplete, subject to change and largely untested at present. | |
57 | [Steve Henson] | |
58 | ||
eead69f5 DSH |
59 | *) Modify fipscanisteronly build option to only build the necessary object |
60 | files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile. | |
61 | [Steve Henson] | |
62 | ||
017bc57b DSH |
63 | *) Add experimental option FIPSSYMS to give all symbols in |
64 | fipscanister.o and FIPS or fips prefix. This will avoid | |
5d439d69 DSH |
65 | conflicts with future versions of OpenSSL. Add perl script |
66 | util/fipsas.pl to preprocess assembly language source files | |
67 | and rename any affected symbols. | |
017bc57b DSH |
68 | [Steve Henson] |
69 | ||
25c65429 DSH |
70 | *) Add selftest checks and algorithm block of non-fips algorithms in |
71 | FIPS mode. Remove DES2 from selftests. | |
72 | [Steve Henson] | |
73 | ||
fe26d066 DSH |
74 | *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just |
75 | return internal method without any ENGINE dependencies. Add new | |
25c65429 | 76 | tiny fips sign and verify functions. |
fe26d066 DSH |
77 | [Steve Henson] |
78 | ||
b3310161 DSH |
79 | *) New build option no-ec2m to disable characteristic 2 code. |
80 | [Steve Henson] | |
81 | ||
30b56225 DSH |
82 | *) New build option "fipscanisteronly". This only builds fipscanister.o |
83 | and (currently) associated fips utilities. Uses the file Makefile.fips | |
84 | instead of Makefile.org as the prototype. | |
85 | [Steve Henson] | |
86 | ||
b3d8022e DSH |
87 | *) Add some FIPS mode restrictions to GCM. Add internal IV generator. |
88 | Update fips_gcmtest to use IV generator. | |
89 | [Steve Henson] | |
90 | ||
bdaa5415 DSH |
91 | *) Initial, experimental EVP support for AES-GCM. AAD can be input by |
92 | setting output buffer to NULL. The *Final function must be | |
93 | called although it will not retrieve any additional data. The tag | |
94 | can be set or retrieved with a ctrl. The IV length is by default 12 | |
95 | bytes (96 bits) but can be set to an alternative value. If the IV | |
96 | length exceeds the maximum IV length (currently 16 bytes) it cannot be | |
97 | set before the key. | |
98 | [Steve Henson] | |
99 | ||
3da0ca79 DSH |
100 | *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the |
101 | underlying do_cipher function handles all cipher semantics itself | |
102 | including padding and finalisation. This is useful if (for example) | |
103 | an ENGINE cipher handles block padding itself. The behaviour of | |
104 | do_cipher is subtly changed if this flag is set: the return value | |
105 | is the number of characters written to the output buffer (zero is | |
106 | no longer an error code) or a negative error code. Also if the | |
d45087c6 | 107 | input buffer is NULL and length 0 finalisation should be performed. |
3da0ca79 DSH |
108 | [Steve Henson] |
109 | ||
2b3936e8 DSH |
110 | *) If a candidate issuer certificate is already part of the constructed |
111 | path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case. | |
112 | [Steve Henson] | |
113 | ||
7c2d4fee BM |
114 | *) Improve forward-security support: add functions |
115 | ||
116 | void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure)) | |
117 | void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure)) | |
118 | ||
119 | for use by SSL/TLS servers; the callback function will be called whenever a | |
120 | new session is created, and gets to decide whether the session may be | |
121 | cached to make it resumable (return 0) or not (return 1). (As by the | |
122 | SSL/TLS protocol specifications, the session_id sent by the server will be | |
123 | empty to indicate that the session is not resumable; also, the server will | |
124 | not generate RFC 4507 (RFC 5077) session tickets.) | |
125 | ||
126 | A simple reasonable callback implementation is to return is_forward_secure. | |
127 | This parameter will be set to 1 or 0 depending on the ciphersuite selected | |
128 | by the SSL/TLS server library, indicating whether it can provide forward | |
129 | security. | |
