摘要:RSA cryptographic algorithm used to encrypt and decrypt the messages for the citation of message in user’s Communication over the secure transmission channel like internet. it will also throw some light on the flaws of some other public key cryptographic algorithms in comparison to RSA algorithm. RSA algorithm will be used to generate key pairs (private key and public key), which are generated using Big integer 19 digit prime value, which will be used to encrypt and decrypt the messages. Algorithm is implemented using GMP library which makes Algorithm work efficiently and time complexity is also reduced.
