Security & privacy
Handle passwords, encryption, metadata cleanup, and verification without oversharing data
Browser-first security helpers for password generation, hashing, encryption, signature checks, metadata removal, and two-factor setup.
Use this collection when the task is reducing exposure: create stronger credentials, inspect cryptographic material, strip hidden metadata, or validate signatures before files and requests leave your device.
