8ab0d50c43 Remove duplicate test from health check. Fix memory leaks by uninstantiating
DRBG before reinitialising it.

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

05272d4c51 Perform health check on all reseed operations not associated with
prediction resistance requests. Although SP 800-90 is arguably unclear
on whether this is necessary adding an additional check has minimal
penalty (very few applications will make an explicit reseed request).

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.

a11f06b2dc More extensive DRBG health check. New function to call health check
for all DRBG combinations.

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.

d98360392a Put quick DRBG selftest return after first generate operation. 2011-09-07 10:26:38 +00:00

bbb19418e6 Add error codes for DRBG KAT failures.
Add abbreviated DRBG KAT for POST which only performs a single generate
operations instead of four.
2011-09-06 20:46:27 +00:00
Dr. Stephen Henson
74c40744ca Don't perform full DRBG health check on all DRBG types on power up, just
one shorter KAT per mechanism.

eb9e63df61 Extension of DRBG selftests using new data.
Test PR and no PR and test initial generate before the reseed too.

Move selftest data to separate fips_drbg_selftest.h header file.

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

7608978861 Update DRBG to use new POST scheme. 2011-04-20 18:05:05 +00:00

49cb5e0b40 Fix memory leaks: uninstantiate DRBG during health checks. Cleanup md_ctx
when performing ECDSA selftest.

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

Allow setting of "rand" callbacks for DRBG.

e06de4dd35 Remove redundant definitions. Give error code if DRBG sefltest fails. 2011-03-31 17:23:12 +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.

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.

Fix warnings.

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