Abstract

Cryptographic Algorithms are sorted into like in size key algorithm and asymmetric key algorithm.. This
grouping is based on the number of keys or key groups used for the encryption and decryption. In like in size key
algorithm ,same single key or key put is used for both encryption and decryption ,where in asymmetric key algorithm;
different keys used. Public key is used for encryption and private key is used for decryption. widely used asymmetric key
or public key systems like RSA ,Diffie-Hellman and like in size key or private key systems DES,3DES ,AES.
