DES encryption was developed by IBM and adopted by the U.S. government in 1977. Its 56-bit cipher was quite secure at its inception, but by the 1990s, the rapid advancement of computing power had made it possible to overcome DES through brute force — a computer could randomly guess the key in less than 24 hours.
