Certificate Overview
Valid Host Names | Not matched | www.lufthansa.com | |
---|---|---|---|
Expires | in 6 months | Valid after Aug 12, 2013 | |
Trust | Trusted | The certificate was issued by VeriSign Class 3 International Server CA - G3 |
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 | No | SSL Session caching allows faster re-establishment of a cached SSL session, improving user experience | |
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 | 4834 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. |
