Hello again. I'm reading these documents and I've seen that the IO struct for these is the BIO struct.
My idea is do something like following (I've generated rsa_public.key with genrsa): $ openssl rsautl -encrypt -in legible_file -pubin -inkey rsa_public.key -out encrypted_file But in my program legible_file and encrypted_file are char[] strings. I'm looking at the EVP_PKEY_encrypt, but the EVP_PKEY_CTX type seems don't exist (I'm using openssl 0.9.8). I'm seeing some tutorials about openssl, but they are quite old (ten years is much time :-)). Are there more updated tutorials in the Internet? I've really liked openssl, but I don't know where to start. Is there a irc channel where users can talk? Regards 2010/8/17 Leandro Santiago <leandrosansi...@gmail.com>: > Thx.
