Openwall researchers, with funding from Rapid7, came up with 17% shorter Boolean expressions representing the DES S-boxes. Openwall's John the Ripper 1.7.8 tests over 20 million of combinations against DES-based crypt(3) per second on Core i7-2600K 3.4 GHz, which roughly corresponds to DES encryption speed of 33 Gbps."
