feat: Enhance algorithm detection and update fixtures
This commit improves the algorithm detection logic to consider multiple sources for parameter extraction. It also updates various fixtures with new UUIDs and algorithm definitions, including RSA, AES, ECDSA, and SHA-256, for better representation. Co-authored-by: script3r <script3r@gmail.com>
