             * 		  IV must be provided when length of the data exceeds 56 bytes. FPE algorithm breaks the long data into 56 s-integer blocks and 
             * 		  uses block chaining algorithm very similar to CBC mode to encrypt and chain the long data.
             * 		  when length of the data does not exceed MAXb value, the IV must be absent.
             * Usage: TweakAlgorithm(Optional) must be from SHA1, SHA256 or None
             * Usage: TweakData(Optional) If, tweak data algorithm is 'None' or absent, 
           	 	    the value must be HEX encoded string representing 64 bit long. In case of valid tweak Algorithm,
            		the tweak data value can be any ASCII string (not necessarily HEX). 
            		Tweak Data is first processed using Tweak Hash Algorithm and the result is truncated to 64 bits
            		for input to the FPE algorithm
