WebJun 2, 2013 · Convert the 16 digit number into its binary representation (54 bits needed). Use a block cipher algorithm with a small blocksize (e.g. Triple-DES has a block size of 64 bits) to encrypt the 54 bits. Convert the encrypted 64 bits into its 20 digit representation. Decrypt: Convert the 20 digit number into its binary 64 bit representation. WebSome substitution ciphers involve using numbers instead of letters.
