Public Methods

Method	Description
CryptoManager ( ) : System
DecryptAES ( byte cipheredPayload, CryptoLevel keysize = CryptoLevel.AES256 ) : byte[]	Decrypts a cyphered key and returns it as clear text
EncryptAES ( byte clearPayload, CryptoLevel keysize = CryptoLevel.AES256 ) : byte[]	Encrypts the un-cyphered data as an array of bytes
GenerateNonce ( Int32 length = 8 ) : byte[]	Generates a random value derived from a set of pre-defined alphanumeric characters.
SetEncryptionLevel ( CryptoLevel keysize = CryptoLevel.AES256 ) : void	Sets or resets the encryption level for the encryption instance

Private Methods

Method	Description
ConfigureCryptoInCode ( ) : void	Loads the crypto properties from hard-coded values. At this time, utilizing an encrypted app.config is not in the specifications.
