Trust

To do authenticated encryption, a certificate needs to be both trusted and valid. Trusted means it is issued by a well-known CA and valid means it is valid for the domain we want to connect to.

Servers supporting SSL 3, but not TLS 1.0 0 results

SSL 3 and TLS 1.0 are very similar, but TLS 1.0 has some small improvements. This table is meant to help judge whether SSL 3 can be disabled by listing the servers that do support SSL 3, but not TLS 1.0.

Target Type When

Servers supporting SSL 2 0 results

SSL 2 is broken and insecure. It is not required for compatibility and servers should disable it.

Servers using <2048-bit RSA certificates which expires after 01-01-2014 0 results

As described in the CA/Browser Forum Baseline Requirements, certificates with RSA keys with less than 2048 bits should not be issued with an notAfter date after 31-12-2013. This list lists all certificates which violate that rule.
