I was recently looking to retrieve information in regards to TLS\SSL compression for a number of websites to address the BREACH vulnerability and found this useful utility at http://www.bolet.org/TestSSLServer/.
TestSSLServer is a command line utility which contacts a TLS\SSL server and returns the following information:
- Supported versions (among SSL 2.0, SSL 3.0, TLS 1.0, TLS 1.1 and TLS 1.2).
- Support of Deflate compression (TLS-level compression, not HTTP-level gzip/deflate compression, which this tool does not consider).
- Supported cipher suites, for each protocol version.
- Server certificate hash and name.
