Thanks Wade. I have been trying(not with much success) to encrypt a certicaicate in PEM format using a rsa key. So from your explanation (given that my certificates arent too big) it should work, right???
Another doubt I want to use RSA_public_encrypt() to encrypt my certificate which means I need to populate an RSA structure. is there a function that populates the structure given a pem file with the key. all i found was RSA_generate_key().I dont want to generate keys...i just want to use existing keys thanks, --- "Wade L.
