sha256state_init :: Sha256State

sha256state_feed :: ByteString -> Sha256State -> Sha256State

Note that this function only processes as many 64-byte blocks as possible, then discards the remainder of the input. Also note that this function does nothing to track the number of bytes that have been fed into the state, which will have to be done externally.

sha256state_fromCtxInplace :: Sha256Ctx -> Sha256State

Cast a Sha256Ctx to a Sha256State, without (much, if any) copying. This has the disadvantage that the result will retain at least 8, and up to 71 unnecessary bytes, depending on the length of the buffer. 72 extra bytes will likely be possible once this binding supports mutable contexts and supports freezing mutable contexts into immutable contexts without copying.

sha256state_fromCtx :: Sha256Ctx -> Sha256State

Cast a Sha256Ctx to a Sha256State. This copies the first 32 bytes of the Sha256Ctx structure, so the result is always as small as possible.
