sslprobe is a tool that maps out a server's TLS configuration and identifies potential problems, such as supporting obsolete protocols or preferring weak cipher suites. I like to play with Qualys' SSLLabs a lot, so I decided to make my own.

From the command-line, type:

go run bin/sslprobe/sslprobe.go [{OPTIONS}] {HOST}

e.g.

go run bin/sslprobe/sslprobe.go github.com

Options include:

• -f or --full: perform cipher preference scans on all supported versions instead of just the highest;
• -q or --quick: don't perform cipher preference scans at all.

Example output:
