Cryptographic settings analyzer library

CryptoLyzer is a cybersecurity tool that can analyze the cryptography-related settings of clients and servers in the case of several different protocols. The tool’s primary purpose is to support end users as well as system administrators, security engineers, auditors, etc., in their work by telling them the details of the currently applied setting and informing them about the potential weaknesses and vulnerabilities.

Unlike many other notable free software projects that focus on just one protocol family, CryptoLyzer wants to be as comprehensive as possible. On the one hand, users can analyze several cryptographic mechanisms (e.g., SSH, HTTP security headers, JA3 tag, and later OpenVPN), not just the most popular TLS protocol. On the other hand, it is possible to test both the standard and special or corner cases. Latter means the tool can test hardly supported, experimental, obsoleted, or even deprecated mechanisms or algorithms, which may carry significant risks. The project intends to learn from the existing projects and integrate their solutions to lower the barrier to good cryptographic settings making communication on private and public networks more secure.
