WebBlowfish is an encryption algorithm that can be used as a replacement for the DES or IDEA algorithms. It is a symmetric (that is, a secret or private key ) block cipher that uses a variable-length key , from 32 bits to 448 bits, making it useful for both domestic and exportable use. (The U. S. government forbids the exportation of encryption ... Webseveral changes of Hill Cipher part to make the both algorithms work together. 2. Theories The symmetric key is one of the cryptographic systems that . uses the same kind of keys in encryption and decryption. Hill Cipher uses the symmetric key in its application. However, the keys used in encryption and decryption are
