Compute Message Authentication Code (tag) over input data

Namespace: CryptoSysAPI
Assembly: diCrSysAPINet (in diCrSysAPINet.dll) Version: 6.22.2.24248 (6.22.2.0)

Syntax

public static byte[] Mac(
	byte[] key,
	byte[] nonce,
	byte[] aad,
	AeadAlgorithm alg
)

Public Shared Function Mac ( 
	key As Byte(),
	nonce As Byte(),
	aad As Byte(),
	alg As AeadAlgorithm
) As Byte()

key Byte: Key of exact length for given algorithm (16 or 32 bytes).
nonce Byte: Nonce of exact length for given algorithm (currently always 12 bytes)
aad Byte: Data to be authenticated
alg AeadAlgorithm: AEAD algorithm to use

Byte
Tag value in byte array, or empty array on error

Remarks

Use General.ErrorCode to find the code of the last error. This is equivalent to Aead.Encrypt with a zero-length plaintext input.
