No, I've omitted all other calls, for safeness I call all OpenSSL_add_all     OpenSSL_add_all_algorithms();     OpenSSL_add_all_ciphers();     OpenSSL_add_all_digests(); R.

Anyone can give me some hints ? I create my RSA key pair with this command: /usr/bin/openssl genrsa -out RSA-1024.key 1024 /usr/bin/openssl rsa -in RSA-1024.key -pubout > RSA-1024-public.key I made the signature with: /usr/bin/openssl dgst -binary -sha512 -sign RSA-1024.key -out serial.SHA512.asc serial.SHA512 If I verify it from CLI all work /usr/bin/openssl dgst -sha512 -verify RSA-1024-public.key -signature serial.txt.SHA512.asc serial.txt.SHA512 Verified OK But when I try to check it from source code all get wrong. Here the code http://nopaste.info/da38ec303b.html What is wrong ? thank you !
