Text Encryption and decryption method havebeen implemented with a symmetric key cipher technique. A symmetric key cipher method converts plain text into its appropriate numerical form and generates a secret key during encryption. The same key is required to decrypt the message during decryption. This method can be used to encrypt passwords to save in the database in an encrypted form. The digital form of data is stored in a matrix. Several operations are performed on the matrix to make the data, secure and less accessible. A slightly different approach has been used to share the secret key during the encryption and decryption mechanisms. The encryption and decryption technique has been implemented using c#. © 2016, International Journal of Pharmacy and Technology. All rights reserved.
