Data encryption is the conversion of data into a form, called a ciphertext, that cannot be easily understood by unauthorized people. Decryption is the process of converting encrypted data back into its original form, so it is easily understood. In literature, different techniques are used for encryption and decryption of text, image, audio and video. RSA (Rivest, Shamir, Aldeman) encryption technique has been used for encryption of text using data encryption technique with square grid transposition with key wrapping.
