HMACSHA3_256 Constructors

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Overloads

HMACSHA3_256()	Initializes a new instance of the HMACSHA3_256 class with a randomly generated key.
HMACSHA3_256(Byte[])	Initializes a new instance of the HMACSHA3_256 class with the specified key data.

HMACSHA3_256()

Source:

HMACSHA3_256.cs

Initializes a new instance of the HMACSHA3_256 class with a randomly generated key.

public:
 HMACSHA3_256();

public HMACSHA3_256 ();

Public Sub New ()

Remarks

HMACSHA3_256 is a type of keyed hash algorithm that is constructed from the SHA3-256 hash function and used as a Hash-based Message Authentication Code (HMAC). The HMAC process mixes a secret key with the message data, hashes the result with the hash function, mixes that hash value with the secret key again, and then applies the hash function a second time. The output hash is 256 bits in length.

This constructor uses a 136-byte, randomly generated key.

HMACSHA3_256(Byte[])

Source:

HMACSHA3_256.cs

Initializes a new instance of the HMACSHA3_256 class with the specified key data.

public:
 HMACSHA3_256(cli::array <System::Byte> ^ key);

public HMACSHA3_256 (byte[] key);

new System.Security.Cryptography.HMACSHA3_256 : byte[] -> System.Security.Cryptography.HMACSHA3_256

Public Sub New (key As Byte())

Parameters

key

Byte[]

The secret key for HMACSHA3_256. The key can be any length.

Exceptions

ArgumentNullException

key is null.
