Michael Brown	5c2d6fa399	[rng] Add ANS X9.82 Approved HMAC_DRBG algorithm ... ANS X9.82 specifies several Approved algorithms for use in a Deterministic Random Bit Generator (DRBG). One such algorithm is HMAC_DRBG, which can be implemented using the existing iPXE SHA-1 and HMAC functionality. This algorithm provides a maximum security strength of 128 bits.
