If others want to chime in, I currently want to do raw SHA256/SHA512 hashes, using code from John the Ripper. I am looking at src/opencl/ office2013_kernel.cl and src/opencl/pbkdf2_hmac_sha512_kernel.cl. They use src/opencl_sha2.h. In src/opencl_office2013_fmt_plug.c, there is no "main" function, so I am wondering where and how the functions in that file are being called. I want to make sure that I'm using the kernels in the right way to get the optimizations that JtR has done.
