Security
| Encryption Ciphers | Weak | Weak encryption ciphers are supported. These are deprecated, and their removal will offer increased security. | |
|---|---|---|---|
| Public Key Size | 1024 bits | Key sizes 1024 bits or larger are considered secure. Be aware that unnecessarily large key sizes will slow down the connection establishment. | |
| Secure Renegotiation | Yes | ||
| Protocols | Insecure | Server supports SSLv2. This is a deprecated and insecure protocol which should be disabled. |
Performance
| HTTP Keepalive | No | Enabling HTTP Keep-Alive will allow subsequent requests to be served faster, without the need to establish a new SSL/TLS connection. | |
|---|---|---|---|
| SSL Session Cache | Yes | ||
| TLS Stateless Resume | No | TLS stateless resume allows for faster re-connections to TLS enabled servers, without needing session state to be stored on the server. | |
| SSL Handshake Size | 2256 bytes | A 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. |
