HMACSHA384 Constructors

Definition

Namespace:

System.Security.Cryptography

Assembly:

System.Security.Cryptography.dll

Initializes a new instance of the HMACSHA384 class.

Overloads

HMACSHA384()	Initializes a new instance of the HMACSHA384 class by using a randomly generated key.
HMACSHA384(Byte[])	Initializes a new instance of the HMACSHA384 class by using the specified key data.

HMACSHA384()

Source:

HMACSHA384.cs

Initializes a new instance of the HMACSHA384 class by using a randomly generated key.

public:
 HMACSHA384();

public HMACSHA384 ();

Public Sub New ()

Remarks

This constructor uses a 64-byte, randomly generated key.

HMACSHA384(Byte[])

Source:

HMACSHA384.cs

Initializes a new instance of the HMACSHA384 class by using the specified key data.

public:
 HMACSHA384(cli::array <System::Byte> ^ key);

public HMACSHA384 (byte[] key);

new System.Security.Cryptography.HMACSHA384 : byte[] -> System.Security.Cryptography.HMACSHA384

Public Sub New (key As Byte())

Parameters

key

Byte[]

The secret key for HMAC computation. The key can be any length. However, the recommended size is 128 bytes. If the key is more than 128 bytes long, it is hashed (using SHA-384) to derive a 48-byte key.

Exceptions

ArgumentNullException

The key parameter is null.

Examples

For an example of how to use this constructor, see the HMACSHA384 class.
