Security & Tokens
These tools help with everyday security tasks: inspecting a JSON Web Token during debugging, computing a checksum, generating a strong password, or sharing a secret without leaving it in a chat history.
Tokens and passwords are sensitive, so these tools do their work in your browser. The one exception is Private Notes, which stores an end-to-end encrypted copy of your note on our server until it is read — the decryption key stays in the link and is never sent to us.
