Can this skill help me audit old codebases?

Absolutely. It contains a list of deprecated and broken algorithms like MD5, SHA-1, and DES that should be flagged and replaced during security reviews.

Does it provide specific code for password hashing?

Yes, it includes detailed C# implementation examples for Argon2id and bcrypt, including recommended work factors and salt handling.

What algorithms does this skill recommend for encryption?

The skill prioritizes modern, authenticated encryption like AES-256-GCM and ChaCha20-Poly1305 for symmetric data, and RSA-OAEP or X25519 for asymmetric operations.

Does it cover post-quantum security?

The skill includes considerations for post-quantum readiness, helping you choose algorithms that provide better long-term security as quantum computing evolves.

Is this skill relevant for web server configuration?

Yes, it includes recommended TLS protocol settings and cipher suites for Nginx to ensure secure transport layer communication.
