Security

Encryption CiphersWeakWeak encryption ciphers are supported. These are deprecated, and their removal will offer increased security.
Public Key Size1024 bitsKey sizes 1024 bits or larger are considered secure. Be aware that unnecessarily large key sizes will slow down the connection establishment.
Secure RenegotiationYes
ProtocolsInsecureServer supports SSLv2. This is a deprecated and insecure protocol which should be disabled.

 

Performance

HTTP KeepaliveNoEnabling HTTP Keep-Alive will allow subsequent requests to be served faster, without the need to establish a new SSL/TLS connection.
SSL Session CacheYes
TLS Stateless ResumeNoTLS stateless resume allows for faster re-connections to TLS enabled servers, without needing session state to be stored on the server.
SSL Handshake Size2256 bytesA smaller SSL handshake means a faster connection. Reducing the number & size of certificates in your chain, and reducing the size of the public key will reduce this.
