When Not To Use It

TODO: Add when not to use.

Known False Negatives

The following patterns are not detected due to static analysis limitations:

Algorithm from Variable

Why: Algorithm names from variables not traced.

// ❌ NOT DETECTED - Algorithm from variable
const algo = config.hashAlgorithm; // May be weak
crypto.createHash(algo);

Mitigation: Hardcode secure algorithms.

Third-party Crypto Libraries

Why: Non-standard crypto APIs not recognized.

// ❌ NOT DETECTED - Third-party
customCrypto.encrypt(data, key);

Mitigation: Review all crypto implementations.

Configuration-based Security

Why: Config-driven security not analyzed.

// ❌ NOT DETECTED - Config-based
const options = getSecurityOptions(); // May be weak

Mitigation: Validate security configurations.
