In the 21st century internet has become a booming technology for information exchange; the basic technique in use is Cryptography. It is an art to achieve security by making the data to non - readable format, it converts plaintext to cipher text, and this scheme of transforming plaintext to cipher text is called cryptography. There are so many cryptographic techniques available. Like symmetric key cryptography, asymmetric key cryptography and combination of all. But as the most secure algorithm can be breached, proposed work will address some of the key issue and their solution.
