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

Namespace:   System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

public HMACSHA384(
	byte[] key


Type: System.Byte[]

The secret key for HMACSHA384 encryption. 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 128-byte key. If it is less than 128 bytes long, it is padded to 128 bytes.

Exception Condition

The key parameter is null.
