C# Class Recognos.Core.PBKDF2SaltedHash

Secure password hash Uses PBKDF2 internally, as implemented by the Rfc2998DeriveBytes class.

Méthodes publiques

Méthode	Description
GenerateHash ( string password ) : string	Generate a salted hash for a password. The returned string contains is formated like this: PBKDF2{nuber of iterations in hexa}.{salt length in hexa}.{salt}{key size in hexa}.{key}
IsPBKDF2Hash ( string hash ) : bool	Returns true if the hash starts with the PBKDF2 prefix
VerifyHash ( string password, string hash ) : bool	Verifies the hash.

Private Methods

Méthode	Description
ComputeHash ( byte password, byte salt, int keySize ) : byte[]	Compute the actual hash for the password and salt using keySize as the key size in bytes.
GenerateSalt ( int size ) : byte[]	Generates the salt.
