Hi: Do you know how to write a client program with certification? I don't know how to setup my client program to use a pem file and let the server side get the certification. In one words, how to write a client program to let the SSL_get_peer_certificate() function call on server side not return NULL but a X509 point. Thanks first here. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
