absorb_padding()

template<size_t HASHBITS, uint8_t DOMAINBITS>

void Ase::SHAKE_Base< HASHBITS, DOMAINBITS >::absorb_padding ( size_t  offset, uint8_t  trail = 0x01  )

protected

Pad stream from offset to block boundary into Keccak state via XOR.

The trail argument must contain the termination bit, optionally preceeded by additional (LSB) bits for domain separation. A permutation is carried out if the trailing padding bits do not fit into the remaining block length.
