I implemeted this in 9c82bcc, using DeepLearningJohnDoes's (a.k.a Janet's) S-boxes except for s4. Boost appears to be in the order of 10% for LM, 20% for DES. Is there any special place to look for more of Romans's work? BTW we now also use LOP3.LUT for many MD4, MD5 and SHA-2 OpenCL formats. Some driver bug prevented me for using it in SHA-1 with nvidia 352.39 (the code is there, just disabled) and md5crypt disable it because of performance regression (still to be investigated). Some formats show a fine boost but none as much as DEScrypt. magnum
