Data Encryption Using Data Encryption Standard(DES) Algorithm

                 The Data Encryption Standard (DES) is a symmetric-key algorithm for the encryption of electronic data. Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext. The keys, in practice, represent a shared secret between two or more parties that can be used to maintain a private information link. This requirement that both parties have access to the secret key is one of the main drawbacks of symmetric key encryption.[Source - wikipedia]
                 Types of symmetric-key algorithms
  • Stream Ciphers
  • Block Ciphers
You can search for the detailed description. I am not going in deep here.
                 Here, with our project we are going to implement DES - Data Encryption Standared
DESuses a single key for both encryption and decryption
