A lightweight and incredibly fast scanner that reports supported cipher suites, key exchanges, and signature algorithms. It is available natively in the Kali Linux tools repository.

If you need a tool to run locally on your server or workstation, these are the industry-standard options for deep analysis:

While primarily a network mapper, its ssl-enum-ciphers script provides a letter grade for each cipher suite, making it one of the most readable tools for a quick security audit. Why You Need a Cipher Check Tool

A fast Python-based library and CLI tool. It is often used in CI/CD pipelines to continuously check servers against Mozilla’s recommended TLS configurations.

Regularly scanning your server is vital for maintaining compliance (such as PCI DSS) and protecting user data. These tools help you identify: testssl/testssl.sh: Testing TLS/SSL encryption ... - GitHub

For administrators and security researchers, downloading an SSL cipher check tool is a critical first step in hardening web infrastructure against modern threats. These tools allow you to audit which encryption algorithms your server supports, ensuring you aren't inadvertently vulnerable to deprecated protocols like SSLv3 or weak ciphers like RC4. Top SSL Cipher Check Tools to Download

A highly flexible, command-line based tool that checks for supported ciphers, protocols, and cryptographic flaws (like Heartbleed or ROBOT). It is 100% open-source and provides a clear, color-coded output.
