pub fn populate_message_block(
w: &mut WitnessFiller<'_>,
m: &[Wire; 16],
bytes: [u8; 64],
)Expand description
Populates the 16 message-block wires of a sha256_compress block from its 64 message bytes.
The bytes are packed big-endian into 16 32-bit words, one per wire, with the high 32 bits left
zero — matching the precondition on m documented in sha256_compress.
