cb71870dfa Use function name FIPS_drbg_health_check() for health check function. 
Add explanatory comments to health check code.

4420b3b17a Revise DRBG to split between internal and external flags. 
One demand health check function.

Perform generation test in fips_test_suite.

Option to skip dh test if fips_test_suite.

a5799bdc48 Allow reseed interval to be set. 2011-09-18 19:36:27 +00:00

de2132de93 Delete strength parameter from FIPS_drbg_generate. It isn't very useful 
(strength can be queried using FIPS_drbg_get_strength ) and adds a
substantial extra overhead to health check (need to check every combination
of parameters).

7fdcb45745 Add support for Dual EC DRBG from SP800-90. Include updates to algorithm 
tests and POST code.

20f12e63ff Add HMAC DRBG from SP800-90 2011-08-08 22:07:38 +00:00

fdb65c836c Don't include des.h any more: it is not needed. 2011-06-16 14:12:42 +00:00

1d55dd86dd Allow applications to specify alternative FIPS RAND methods if they 
are sure they are OK.

API to retrieve FIPS rand method.

b8b6a13a56 Add continuous RNG test to entropy source. Entropy callbacks now need 
to specify a "block length".

Dr. Stephen Henson
14264b19de Add periodic DRBG health checks as required by SP800-90. 2011-04-20 17:06:38 +00:00

68ea88b8d1 New function to return security strength of PRNG. 2011-04-09 16:49:59 +00:00
Dr. Stephen Henson
05e24c87dd Extensive reorganisation of PRNG handling in FIPS module: all calls 
now use an internal RAND_METHOD. All dependencies to OpenSSL standard
PRNG are now removed: it is the applications resposibility to setup
the FIPS PRNG and initalise it.

Initial OpenSSL RAND_init_fips() function that will setup the DRBG
for the "FIPS capable OpenSSL".

cab0595c14 Rename deprecated FIPS_rand functions to FIPS_x931. These shouldn't be 
used by applications directly and the X9.31 PRNG is deprecated by new
FIPS140-2 rules anyway.

e5cadaf8db Only zeroise sensitive parts of DRBG context, so the type and flags 
are undisturbed.

Allow setting of "rand" callbacks for DRBG.

212a08080c Unused, untested, provisional RAND interface for DRBG. 2011-03-31 18:06:07 +00:00
Dr. Stephen Henson
52b6ee8245 Reorganise DRBG API so the entropy and nonce callbacks can return a 
pointer to a buffer instead of copying to a fixed length buffer. This
removes the entropy and nonce length restrictions.
 2011-03-31 17:15:54 +00:00
Dr. Stephen Henson
dad7851485 Allow setting of get_entropy and get_nonce callbacks outside test mode. 
Test mode is now set when a DRBG context is initialised.

96ec46f7c0 Implement health checks needed by SP800-90. 
Fix warnings.

Instantiate DRBGs at maximum strength.

fbbabb646c Add extensive DRBG selftest data and option to corrupt it in fips_test_suite. 2011-03-16 15:52:12 +00:00

1b76fac5ae Check requested security strength in DRBG. Add function to retrieve the 
security strength.

868f12988c Updates to DRBG: fix bugs in infrastructure. Add initial experimental 
algorithm test generator.

591cbfae3c Initial, provisional, subject to wholesale change, untested, probably 
not working, incomplete and unused SP800-90 DRBGs for CTR and Hash modes.

Did I say this was untested?

2b4b28dc32 And so it begins... again. 
Initial FIPS 140-2 code ported to HEAD. Doesn't even compile yet, may have
missing files, extraneous files and other nastiness.

In other words: it's experimental ATM, OK?
