The federal encryption standard for unclassified government computer data and communications, an encryption algorithm called Lucifer, had been developed by IBM in the early 70s.
It was later certified by a civilian agency, the National Bureau of Standards (now NIST), as the Data Encryption Standard (DES) in 1976.
Unlike public key cryptography which uses two keys (either one of which may be used to encrypt, and the other to decrypt), DES was a symmetric key system, using a single key to both encrypt and decrypt.
Because of the single key, DES could be used for encryption or authentication, but not both simultaneously.

Through the American Bankers Association and ANSI's Financial Institution Wholesale Security Working Group, Lucifer Encryption, now renamed DES, entered the banking world as a method of encryption and message authentication in electronic funds transfer.
