SSL settings can be modified here to configure the details of the HTTPS connection for an individual virtual host.
Enable OCSP stapling | This option enables Online Certificate Status Protocol OCSP stapling. The Online Certificate Status Protocol (OCSP) was created as an alternative to the Certificate Revocation List (CRL) protocol. Both protocols are used to check whether an SSL Certificate has been revoked. |

Server certificate | A selectable list of SSL/TLS certificates for this virtual host. |
E-mail address | The email address of the server administrator. |
Note: This email address is used as contact information for Let's Encrypt functionality. | |
Content of SSL server certificate | Shows the content of the certificate. |
Content of CA chain | Shows the chain of trust of the certificate chain. |
Note: OCSP requires valid chain information for certificate validation - see also Tab – Client Certificates. | |
Content of SSL root CA certificate | Shows the content of the certificate. |

Note that the Airlock Gateway default SSL/TLS settings are optimized for compatibility and security. If you override the default settings you will no longer profit from these optimizations in further Airlock Gateway updates.
We strongly recommend using the default TLS settings of Airlock Gateway in order to mitigate the risk of attacks based on older protocol versions. A list of known attacks on SSL/TLS can be found here: Attacks on TLS and Airlock Gateway Protection Mechanisms
Weakening SSL/TLS settings will most likely result in low scores for scanners like ssllabs.com or pentester reporting the security issues associated with old ciphers and protocols.
