ISO 9797-1 MAC Algorithm 3

Perform MAC computation on the block in.

The computation requires k_mac, a 16bytes key that will be split in two during the computation.

Unless the MAC computation is for the Mutual Authenticate command, SSC (Send Session Counter) is required, otherwise the MAC will be rejected.

Warning: No padding is performed.

Implements logicalaccess::ISO24727Crypto.

◆ compute_mac_key()

ByteVector EPassCrypto::compute_mac_key	(	const ByteVector &	seed,

◆ compute_session_keys()

void EPassCrypto::compute_session_keys	(	const ByteVector &	k_icc,
		const ByteVector &	random_icc
	)

overridevirtual
