DES

DES

Data Encryption Standard. Algorithm for secret-key cryptography (where both sender and receiver must know the same secret key). DES uses a 56bit key to encrypt data to be transmitted, the receiver uses the same key to decrypt the data. Encrypted data cannot be decrypted without the key or brute force attack methods, which may not be viable because of the time required.
