Developed as part of G-SEC's investigation into the "Secure SSL/TLS configuration Report 2010" (to be published) we developed this little tool called SSL Audit. (More to follow in the next days - stay tuned).
SSL Audit scans web servers for SSL support, unlike other tools it is not limited to ciphers supported by SSL engines such as OpenSSL or NSS and can detect all known cipher suites over all SSL and TLS versions.
Apart from scanning available ciphersuites it has an interesting tidbit : The Fingerprint mode (Experimental). Included is an experimental fingerprint engine that tries to determine the SSL Engine used server side. It does so by sending normal and malformed SSL packets that can be interpreted in different ways.
SSL Audit is able to fingerprint :
· IIS7.5 (Schannel)
· IIS7.0 (Schannel)
· IIS 6.0 (Schannel)
· Apache (Openssl)
· Apache (NSS)
· RSA BSAFE
