Performs 2 rounds of SHA256 operation using an initial SHA256 state
(C,D,G,H) from a
, an initial SHA256 state (A,B,E,F) from b
, and a
pre-computed sum of the next 2 round message values (unsigned 32-bit
integers) and the corresponding round constants from k
, and store the
updated SHA256 state (A,B,E,F) in dst.
