Cipher.DecryptAEAD(Byte[], Byte[], Byte[], AeadAlgorithm) Method
Decrypt data using the AES-GCM authenticated encryption algorithm.
Syntax
[C#]
public static byte[] DecryptAEAD(
byte[] input,
byte[] key,
byte[] iv,
AeadAlgorithm aeadAlg
)
[VB]
Public Shared Function DecryptAEAD (
input As Byte(),
key As Byte(),
iv As Byte(),
aeadAlg As AeadAlgorithm
) As Byte()
Parameters
- input Byte
- Input data to be decrypted.
- key Byte
- Key of exact length for algorithm (16, 24 or 32 bytes).
- iv Byte
- Initialization Vector (IV) (aka nonce) exactly 12 bytes long.
- aeadAlg AeadAlgorithm
- Authenticated encryption algorithm.
Return Value
BytePlaintext in a byte array, or empty array on error (an empty array may also be the correct result - check
General.ErrorCode for details).
Remarks
The input must include the 16-byte tag appended to the ciphertext.
The output will be exactly 16 bytes shorter than the input.
In all cases the IV must be exactly 12 bytes (96 bits) and the tag must be exactly 16 bytes (128 bits).
