7b3a9b00 | 5 | Changes between 1.0.1 and 1.1.0 [xx XXX xxxx] |
aaf35f11 | 6 | |
05e24c87 DSH |
7 | *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies |
8 | to OpenSSL RAND code and replace with a tiny FIPS RAND API which also | |
9 | performs algorithm blocking for unapproved PRNG types. Also do not | |
10 | set PRNG type in FIPS_mode_set(): leave this to the application. | |
11 | Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with | |
12 | the standard OpenSSL PRNG. | |
13 | [Steve Henson] | |
14 | ||
cab0595c DSH |
15 | *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*. |
16 | This shouldn't present any incompatibility problems because applications | |
17 | shouldn't be using these directly and any that are will need to rethink | |
18 | anyway as the X9.31 PRNG is now deprecated by FIPS 140-2 | |
19 | [Steve Henson] | |
20 | ||
96ec46f7 DSH |
21 | *) Extensive self tests and health checking required by SP800-90 DRBG. |
22 | Remove strength parameter from FIPS_drbg_instantiate and always | |
23 | instantiate at maximum supported strength. | |
24 | [Steve Henson] | |
25 | ||
0deea0e0 | 26 | *) Add SRP support. |
d4f3dd5f | 27 | [Tom Wu <tjw@cs.stanford.edu> and Ben Laurie] |
0deea0e0 | 28 | |
8857b380 DSH |
29 | *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing. |
30 | [Steve Henson] | |
31 | ||
11e80de3 DSH |
32 | *) New algorithm test program fips_dhvs to handle DH primitives only testing. |
33 | [Steve Henson] | |
34 | ||
35 | *) New function DH_compute_key_padded() to compute a DH key and pad with | |
36 | leading zeroes if needed: this complies with SP800-56A et al. | |
37 | [Steve Henson] | |
38 | ||
591cbfae DSH |
39 | *) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by |
40 | anything, incomplete, subject to change and largely untested at present. | |
41 | [Steve Henson] | |
42 | ||
eead69f5 DSH |
43 | *) Modify fipscanisteronly build option to only build the necessary object |
44 | files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile. | |
45 | [Steve Henson] | |
46 | ||
017bc57b DSH |
47 | *) Add experimental option FIPSSYMS to give all symbols in |
48 | fipscanister.o and FIPS or fips prefix. This will avoid | |
5d439d69 DSH |
49 | conflicts with future versions of OpenSSL. Add perl script |
50 | util/fipsas.pl to preprocess assembly language source files | |
51 | and rename any affected symbols. | |
017bc57b DSH |
52 | [Steve Henson] |
53 | ||
25c65429 DSH |
54 | *) Add selftest checks and algorithm block of non-fips algorithms in |
55 | FIPS mode. Remove DES2 from selftests. | |
56 | [Steve Henson] | |
57 | ||
fe26d066 DSH |
58 | *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just |
59 | return internal method without any ENGINE dependencies. Add new | |
25c65429 | 60 | tiny fips sign and verify functions. |
fe26d066 DSH |
61 | [Steve Henson] |
62 | ||
b3310161 DSH |
63 | *) New build option no-ec2m to disable characteristic 2 code. |
64 | [Steve Henson] | |
65 | ||
30b56225 DSH |
66 | *) New build option "fipscanisteronly". This only builds fipscanister.o |
67 | and (currently) associated fips utilities. Uses the file Makefile.fips | |
68 | instead of Makefile.org as the prototype. | |
69 | [Steve Henson] | |
70 | ||
b3d8022e DSH |
71 | *) Add some FIPS mode restrictions to GCM. Add internal IV generator. |
72 | Update fips_gcmtest to use IV generator. | |
73 | [Steve Henson] | |
74 | ||
bdaa5415 DSH |
75 | *) Initial, experimental EVP support for AES-GCM. AAD can be input by |
76 | setting output buffer to NULL. The *Final function must be | |
77 | called although it will not retrieve any additional data. The tag | |
78 | can be set or retrieved with a ctrl. The IV length is by default 12 | |
79 | bytes (96 bits) but can be set to an alternative value. If the IV | |
80 | length exceeds the maximum IV length (currently 16 bytes) it cannot be | |
81 | set before the key. | |
82 | [Steve Henson] | |
83 | ||
3da0ca79 DSH |
84 | *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the |
85 | underlying do_cipher function handles all cipher semantics itself | |
86 | including padding and finalisation. This is useful if (for example) | |
87 | an ENGINE cipher handles block padding itself. The behaviour of | |
88 | do_cipher is subtly changed if this flag is set: the return value | |
89 | is the number of characters written to the output buffer (zero is | |
90 | no longer an error code) or a negative error code. Also if the | |
d45087c6 | 91 | input buffer is NULL and length 0 finalisation should be performed. |
3da0ca79 DSH |
92 | [Steve Henson] |
93 | ||
2b3936e8 DSH |
94 | *) If a candidate issuer certificate is already part of the constructed |
95 | path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case. | |
96 | [Steve Henson] | |
97 | ||
7c2d4fee BM |
98 | *) Improve forward-security support: add functions |
99 | ||
100 | void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure)) | |
101 | void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure)) | |
102 | ||
103 | for use by SSL/TLS servers; the callback function will be called whenever a | |
104 | new session is created, and gets to decide whether the session may be | |
105 | cached to make it resumable (return 0) or not (return 1). (As by the | |
106 | SSL/TLS protocol specifications, the session_id sent by the server will be | |
107 | empty to indicate that the session is not resumable; also, the server will | |
108 | not generate RFC 4507 (RFC 5077) session tickets.) | |
109 | ||
110 | A simple reasonable callback implementation is to return is_forward_secure. | |
111 | This parameter will be set to 1 or 0 depending on the ciphersuite selected | |
112 | by the SSL/TLS server library, indicating whether it can provide forward | |
113 | security. | |
