Security & Crypto tools
Credential and token tooling that runs entirely in your browser using the Web Crypto API: HMAC, password hashes, TOTP, JWT, QR provisioning and strength analysis.
Hash Generator
Generate SHA-1, SHA-256, SHA-384 and SHA-512 digests of any text using the browser Web Crypto API - nothing is uploaded.
HMAC Generator
Generate HMAC-SHA1, SHA-256, SHA-384 or SHA-512 signatures from a message and key, in hex and base64, computed locally.
Password & Secret Generator
Generate cryptographically random passwords, RADIUS shared secrets and pre-shared keys using the browser CSPRNG, with entropy calculated honestly.
Password Strength Checker
Estimate real password entropy, detect patterns that make it weaker than it looks, and see honest crack-time estimates for different attack scenarios.
