Free Online Security and Encryption Tools

Security tools for everyday development work. Hash text or files with MD5, SHA or bcrypt, encrypt and decrypt text with AES, and sign or decode JWTs and HMAC signatures. These encryption tools also generate RSA key pairs, UUIDs, ULIDs, secure tokens, passphrases, OTP codes and BIP39 phrases, check password strength and verify PDF signatures. Most tools run locally, so your secrets stay in your browser.
