Encryption is a process of generating secret text from the input text using a secret key and an encryption algorithm. Input text is referred to as plain text and the secret text generated is known as cipher text. Encryption algorithms are mainly divided into two categories which are symmetric key encryption algorithm and asymmetric key encryption algorithm. In symmetric key encryption algorithm the same key is used by both sender and receiver but in asymmetric key algorithm sender and receiver both uses the different keys.
