Certificate Overview
| Valid Host Names | Matched | cardupgrade.citi.com www.cardupgrade.citi.com | |
|---|---|---|---|
| Expires | in 2 years | Valid after Dec 10, 2015 | |
| Trust | Trusted | The certificate was issued by Symantec Class 3 EV SSL 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 | 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 | 4016 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. |
