C-LAB · Cybersecurity lab
Open, local-first security tools for journalists and human-rights defenders. Everything here is designed so your files, keys and scans stay on your device. Pick a task, or press Ctrl/⌘ K to search.
Verify SHA-256/1/512 and MD5 in your browser, or build an evidence manifest for a whole folder and re-verify it later. Files never leave your device.
Encrypted, offline vault for your API keys. AES-256-GCM with Argon2id, in the browser or as a signed macOS desktop app.
Look up known vulnerabilities for your device or software against the NIST NVD, with open and fixed CVEs separated. A same-origin proxy keeps your IP away from NIST.
See what a photo reveals before you publish it: GPS, identity, device serials, hidden thumbnails. Risk verdict first, full metadata dump after. The image never leaves your device.
Scan your own computer and get a plain-language security report, with an encrypted local history. Nothing leaves your machine unless you export it.
Check your own phone over USB from your computer, no root or jailbreak. The mobile sibling of ComputerCheck, informed by Amnesty MVT and Citizen Lab indicators.
Audit the website you administer, from the inside out: TLS, headers and OWASP-informed checks, in the same findings format as the device scanners.
Check and harden the WiFi of a small newsroom, guided step by step. Built for teams without an IT department.
