Certificate Overview
| Valid Host Names | Not matched | cyberdatastorm.com | |
|---|---|---|---|
| Expires | in 3 months | Valid after Dec 14, 2023 | |
| Trust | Trusted | The certificate was issued by R3 |
Security
| Encryption Ciphers | OK | ||
|---|---|---|---|
| Public Key Size | 256 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 | TLSv1.2, TLSv1.3 |
Performance
| HTTP Keepalive | Yes | ||
|---|---|---|---|
| SSL Handshake Size | 4539 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. |
