BinHexToBinary ( string hex ) : byte[]	Turns a BinHex string that contains raw byte values into a byte array
BinaryToBinHex ( byte data ) : string	Converts a byte array into a BinHex string. Example: 01552233 where the numbers are packed byte values.
ComputeHash ( byte byteData, string hashAlgorithm, byte saltBytes, bool useBinHex = false ) : string	Generates a hash for the given plain text value and returns a base64-encoded result. Before the hash is computed, a random salt is generated and appended to the plain text. This salt is stored at the end of the hash value, so it can be used later for hash verification.
ComputeHash ( string plainText, string hashAlgorithm, byte saltBytes, bool useBinHex = false ) : string	Generates a hash for the given plain text value and returns a base64-encoded result. Before the hash is computed, a random salt is generated and appended to the plain text. This salt is stored at the end of the hash value, so it can be used later for hash verification.
