There are many aspects to security ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of secret key Cryptography. It is the automated method in which security goals are accomplished. It includes the process of encryption that converts plain-text into cipher-text. The process of decryption reconverts the cipher-text into plain-text. Secure communication is the prime requirement of every organization. To achieve this, one can use many techniques or algorithms available for Cryptography.
