            SSL_CTX_use_certificate(ctx,
              cert)
            

            After
              this line is it safe to free cert object while ctx is
              still used later on?
            

    SSL_CTX_use_certificate(ctx, cert), on successful return, takes an
    additional reference on the supplied |cert| argument to account for
    the pointer in |ctx|.  Thus, the caller of SSL_CTX_use_certificate()
    can safely call X509_free(cert) to release the caller's local
    reference, while the |ctx| retains a pointer to |cert|.
