About security

Security utilities for developers and admins: generate and verify hashes and HMACs, encrypt and decrypt with AES, hash and check bcrypt passwords, generate RSA key pairs, create and decode JWTs, produce TOTP codes, generate BIP39 mnemonics, decode SSL certificates and test password strength.

Because these tools handle sensitive material, they are built to run entirely in your browser — keys and plaintext never leave your device.

Frequently asked questions

Is it safe to encrypt real data here?
The cryptography runs locally with the Web Crypto API and audited libraries, and nothing is transmitted. As with any browser tool, use a trusted device and avoid public computers for sensitive work.
