The Data Encryption Standard (DES) is a symmetric-key block cipher. DES is an implementation of a Feistel Cipher. It uses 16 round Feistel structure. The block size of DES is 64-bit. Though, key length is 64-bit, DES has an effective key length of 56 bits, since 8 of the 64 bits of the key are not used by the encryption algorithm. RC2 (Rivest Cipher) is a symmetric-key block cipher. Once the files are saved in a respective technique, user will get LSB encrypted image through email. Which will act as key to access a particular file.
