WebDES is a symmetric key block cipher. Symmetric key block ciphers process fixed-size blocks simultaneously using the same key to encrypt the data. The block size of a cipher refers to the number of bits that are processed together. The original DES algorithm specified the use of 56-bit keys. Webkey transmiited with the data, the chances of data being decrypted are null. • A symmetric cryptosystem uses password authentication to prove the receiver’s identity. • A system only which possesses the secret key can decrypt a message. DISADVANTAGES • Symmetric cryptosystems have a problem of key transportation. The secret
