Applied hybrid cryptography in key-pair generation of RSA implementation

A key is a crucial factor in any cryptographic system. Devoid of a key, the algorithm would not produce any fruitful result. Key is being used in encryption, decryption and other cryptographic algorithms such as digital signature schemes and MAC (message authentication codes). The only thing that should be kept secret in a sound cryptosystem is the key so the key generation is important in implementation of cryptographic algorithms. In this paper the key generation module of the developed application package has been discussed which generates private and public keys in pairs using RSA and the corresponding private keys generated are encrypted using DES algorithm to apply hybrid cryptography.
