Functions

func F

func F(h *[8]uint64, m [16]uint64, c [2]uint64, f bool, rounds uint32)

F is a compression function for BLAKE2b. It takes as an argument the state vector `h`, message block vector `m`, offset counter `t`, final block indicator flag `f`, and number of rounds `rounds`. The state vector provided as the first parameter is modified by the function.
