The code seems to be almost pristine OpenSSL C code. Nothing special except he skips update() and inlines that functionality in the loop. Looks like a good idea. Our current sha1 kernel could easily be modified to keep a context. He decrypts in GPU too. For -hp mode that might be a good idea but for -p mode I suspect AES-NI is they key to success if your CPU supports it. I have tried crark but not igrargpu, are they about the same in speed on a specific card? magnum
