Certificate Overview
Valid Host Names | Not matched | *.connect.facebook.com connect.facebook.com | |
---|---|---|---|
Expires | in 9 months | Valid after Mar 1, 2014 | |
Trust | Trusted | The certificate was issued by DigiCert High Assurance CA-3 |
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 | Yes | ||
Protocols | OK | SSLv3, TLSv1 |
Performance
HTTP Keepalive | Yes | ||
---|---|---|---|
SSL Session Cache | Yes | ||
TLS Stateless Resume | Yes | ||
SSL Handshake Size | 3968 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. |
