Hi, I am very new at using OpenSSL, so bear with me please. We are using OpenSSL, and all is great. I have been saked to recompile our application to have OpenSSL use GMP to increase the performance. Seems simple enough. I have compiled GMP, I also have recompiled OpenSLL to use GMP with "-DOPENSSL_USE_GMP -I<includepath> -L<libpath> -lgmp". I made sure that ENGINE_load_gmp(); was called and ENGINE_register_all_complete();, but I do not see any perfromance improvement. I was under the impression, silly me, that I just needed to compile GMP, recompile OpenSSL with the proper switch to get this thing going. I must be missing something, but what? Can anybody help... or at least point me in the rigth direction. Like I said I have tried to make sure that the GMP engine gets loaded, and it seems to be loaded. I iterate through the list of ENGINE and I see the GMP engine loaded. But it does not get initialized, bind_helper does get called though. Thank you -Mart
