Security

Encryption CiphersOK
Public Key Size4096 bitsKey sizes 1024 bits or larger are considered secure. Be aware that unnecessarily large key sizes will slow down the connection establishment.
Secure RenegotiationYes
ProtocolsOKSSLv3, TLSv1

 

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 CacheNoSSL Session caching allows faster re-establishment of a cached SSL session, improving user experience
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 Size5233 bytesThe amount of data exchanged to establish a session with this server is large. This will result in a slower initial connection.

Using a certificate with fewer intermediate chains and / or a smaller public key size can reduce the amount of data.
