Subject: [PATCH 1/4] fips: add self-tests for HKDF
096318
096318
FIPS140-2 IG D.8 mandates self-test on approved KDF algorithms.  As
096318
the guidance only requires running a single instance of each KDF
096318
mechanism, this only exercises HKDF-Extract and HKDF-Expand operations
096318
with HMAC-SHA-256 as the underlying MAC.
096318
096318
Although HKDF is non-approved, it would be sensible to do that as it
096318
will be approved in FIPS140-3.

Subject: [PATCH 3/4] fips: add self-tests for TLS-PRF
096318
096318
FIPS140-2 IG D.8 mandates self-tests on approved KDF algorithms.  As
096318
the guidance only requires to run a single instance of each KDF
096318
mechanism, this only exercises TLS1.2 PRF with HMAC-SHA-256 as the
096318
underlying MAC algorithm.
