Public Methods

Method	Description
Create ( string password ) : PasswordHash	Creates a salted PBKDF2 hash of the password.
Validate ( string password, byte hash, byte salt ) : bool	Validates a password against given hash and salt.

Private Methods

Method	Description
Equals ( byte a, byte b ) : bool	Compares two byte arrays in length-constant time. This comparison method is used so that password hashes cannot be extracted from on-line systems using a timing attack and then attacked off-line.
PBKDF2 ( string password, byte salt, int iterations, int outputBytes ) : byte[]	Computes the PBKDF2-SHA1 hash of a password.
PasswordHash ( byte hash, byte salt ) : System.Security.Cryptography	Initializes a new instance of the PasswordHash class.
