The principal goal of designing any encryption algorithm is to hide the original message and send the non readable text message to the receiver so that secret message communication can take place over the web. The strength of an encryption algorithm depends on the difficulty of cracking the original message. A number of symmetric key encryption algorithms like DES, TRIPLE DES, AES, BLOWFISH have been developed to provide greater security affects one over the other.
