Cipherscan is a command-line tool that tests which SSL/TLS ciphersuites a target server supports and in what order, wrapping the openssl s_client command. It also extracts certificate details, TLS options, and OCSP stapling information.

Use cases

• audit which ssl ciphers a server supports
• check tls cipher ordering on a domain
• find weak or deprecated ciphersuites on a server
• test starttls services like xmpp for cipher support
• extract certificate and ocsp stapling info from a tls endpoint
• verify server tls configuration against best practices

When to choose

• you need a quick unix command-line scan of a target's TLS ciphers
• you want cipher ordering and certificate details without a full scanner
• you need to test STARTTLS protocols like xmpp or smtp

When to avoid

• you need a full vulnerability scanner with CVE detection
• you want a GUI or continuous TLS monitoring dashboard
• you are on Windows without a unix-like environment
