e0d1a2f80a Always return multiple of block length bytes from default DRBG seed 
callback.

Handle case where no multiple of the block size is in the interval
[min_len, max_len].

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

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

55e328f580 Add error for health check failure. 
Rebuild all FIPS error codes to clean out old obsolete codes.

f3823ddfcf Before initalising a live DRBG (i.e. not in test mode) run a complete health 
check on a DRBG of the same type.

42bd0a6b3c Update fipssyms.h to keep all symbols in FIPS,fips namespace. 
Rename drbg_cprng_test to fips_drbg_cprng_test.

Remove rand files from Makefile.fips.

ded1999702 Change RNG test to block oriented instead of request oriented, add option 
to test a "stuck" DRBG.

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

Allow setting of "rand" callbacks for DRBG.

011c865640 Initial switch to DRBG base PRNG in FIPS mode. Include bogus seeding for 
test applications.

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.

dad7851485 Allow setting of get_entropy and get_nonce callbacks outside test mode. 
Test mode is now set when a DRBG context is initialised.

1e803100de Implement continuous RNG test for SP800-90 DRBGs. 2011-03-17 18:53:33 +00:00

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?
