SSL: ciphers now set before loading certificates (ticket #2035). To load old/weak server or client certificates it might be needed to adjust the security level, as introduced in OpenSSL 1.1.0. This change ensures that ciphers are set before loading the certificates, so security level changes via the cipher string apply to certificate loading.
