HMACMD5 Constructor

Initializes a new instance of the HMACMD5 class with a randomly generated key.

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

public HMACMD5()

HMACMD5 is a type of keyed hash algorithm that is constructed from the MD5 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 will be 128 bits in length.

With this constructor, a 64-byte, randomly generated key is used.
