CreateHMAC() 공개 정적인 메소드

Create an IncrementalHash for the Hash-based Message Authentication Code (HMAC) algorithm utilizing the hash algorithm specified by hashAlgorithm, and a key specified by key.

public static CreateHMAC ( HashAlgorithmName hashAlgorithm, byte key ) : IncrementalHash
hashAlgorithm	HashAlgorithmName	The name of the hash algorithm to perform within the HMAC.
key	byte	/// The secret key for the HMAC. The key can be any length, but a key longer than the output size /// of the hash algorithm specified by will be hashed (using the /// algorithm specified by ) to derive a correctly-sized key.
