The goal of this project was design of a hardware implementation of the crypt(3) function found on most Unix machines and Unix clones, used to encrypt user passwords in the password database. The purpose for a crypt(3) function implementation in hardware is to increase the speed of its operation in comparison to current software implementations. Our major contribution was the modification of the Data Encryption Standard algorithm to compute the crypt(3) function. Integral to this modification was the design of a Waksman network used to compute dynamic permutations. A VHDL hardware description was written and simulated. Test results indicate that a hardware implementation of our design would perform significantly faster than current software implementations of the crypt(3) function.
