Security

Encryption CiphersOK
Public Key Size2048 bitsKey sizes 1024 bits or larger are considered secure. Be aware that unnecessarily large key sizes will slow down the connection establishment.
Secure RenegotiationNoThis server is vulnerable to man-in-the-middle attacks by allowing insecure renegotiation.
ProtocolsOKSSLv3, TLSv1

 

Performance

HTTP KeepaliveYes
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 Size4529 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.
