According to the website:

SSLScan queries SSL services, such as HTTPS, in order to determine the ciphers that are supported.  SSLScan is designed to be easy, lean and fast.  The output includes prefered ciphers of the SSL service, the certificate and is in Text and XML formats.

SSLScan is a very useful tool to quickly determine the cipher suites support by one or more websites.  Below is a screenshot of the output of the command:

# sslscan –no-failed <target>.net:443

Download it from here, or if you are running from Debian or Ubuntu, you can simply issue the command:

# apt-get install sslscan
