[Beast-Check] SSL/TLS BEAST Vulnerability Check

Read

A small perl script that checks a target server whether it is prone to BEAST vulnerability via target preferred cipher. It assumes no workaround (i.e. EMPTY FRAGMENT) applied in target server. Some sources said this workaround was disabled by default for compatibility reasons. This may be the reason why RC4 ciphersuite was widely chosen as highest preferred ciphersuite for the primary workaround.
