Security
| Encryption Ciphers | OK | ||
|---|---|---|---|
| Public Key Size | 2048 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 | No | This server is vulnerable to man-in-the-middle attacks by allowing insecure renegotiation. | |
| Protocols | OK | SSLv3, TLSv1 |
Performance
| HTTP Keepalive | Yes | ||
|---|---|---|---|
| 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 | 4529 bytes | The 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. |
