# Detectors overview

Detectors extract cryptographic evidence. They do not classify quantum exposure — that is the classifier's job after correlation.

| Detector      | Input                            | Output signal                                       |
| ------------- | -------------------------------- | --------------------------------------------------- |
| Source        | Parsed source via rule packs     | Call sites, primitives, parameters                  |
| Dependencies  | Manifests / lockfiles            | Crypto libraries present                            |
| Certificates  | PEM/DER/P12/JKS/SSH key material | Algorithms, sizes, curves, validity (metadata only) |
| Configuration | TLS/SSH/JWT and related config   | Configured suites, versions, algorithms             |

## Design constraints

* Prefer AST / structured parsing over regex; regex is an explicit fallback with lowered confidence.
* Never emit key material — metadata only, redacted snippets.
* Unparseable files must produce warnings.
