You just configure two private keys and two certificate chains by calling: if (SSL_CTX_use_certificate_chain_file(ctx, cert_file) <= 0) { /* error */; } if (SSL_CTX_use_PrivateKey_file(ctx, key_file, SSL_FILETYPE_PEM) <= 0) { /* error */; } if (SSL_CTX_check_private_key(ctx) != 0) { /* error */; } once for each "cert_file" and associated "key_file" (the same file often holds both, in which case cert_file == key_file). The SSL error stack will contain error details. The SSL library will automatically select the appropriate key and certificate chain. -- Viktor. -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
