How does it help with key management?

It generates precise, secure key specifications and rotation policies based on the specific algorithm and intended purpose of the key.

Does this skill support Post-Quantum Cryptography (PQC)?

Yes, the latest production-grade version includes support for PQC standards to ensure future-proof security for your applications.

Can it identify insecure hashing algorithms?

Yes, it automatically flags deprecated algorithms like MD5, SHA1, and DES, recommending secure modern alternatives like SHA-256 or Argon2id.

Why is retry logic disabled for this skill?

Retries are intentionally disabled for cryptographic operations to prevent potential timing leak attacks that could compromise your system's security.
