Scan your configs & IaC

Config files declare cryptography your code never mentions: the cipher suites nginx will accept, the key spec Terraform will mint, the SSH keys allowed into a box. PQLens reads the declarations, so tomorrow’s crypto is in today’s inventory.

Config tab → pick your repo or config folder
Free · runs in your browser (WebAssembly) — nothing about your code, configs or certificates leaves the machine.

How it works

  1. Open the Config tab and pick a repo or config folder.
  2. Web-server TLS settings (nginx, Apache, HAProxy) are parsed: protocol floors and cipher lists.
  3. Terraform and cert-manager resources are read for the key algorithms and sizes they will create.
  4. SSH authorized_keys files are inventoried by key algorithm and size.

Declared crypto is a leading indicator

A live TLS probe tells you what a server negotiated today; the nginx config tells you everything it would accept, including the TLS 1.0 floor someone set in 2015. And a Terraform module that requests RSA-2048 keys will keep minting quantum-vulnerable keys with every apply until the module changes. Fixing the declaration fixes the future — which is why config is its own surface.

Pairs well with a live TLS scan

Scan the config, then probe the live endpoint of the same service — the difference between what a config declares as acceptable and what actually gets negotiated today is often the most useful finding.

Frequently asked questions

Which config formats are understood?

nginx, Apache and HAProxy TLS settings; Terraform and cert-manager key/certificate specs; and SSH authorized_keys files.

Does it change or lint my configs?

No. It is read-only discovery, run entirely in your browser — it reports what the files declare and classifies it; it never rewrites anything, and the files never leave the tab.

Why scan configs when I can probe the live endpoint?

The live probe shows one negotiated result; the config shows the full accepted range and what future infrastructure will be created with. You want both in the inventory.
