About Security Tools

Our Security Tools cover everyday cryptography and safety checks. Generate and verify hashes (MD5, SHA), test password strength, encrypt and decrypt text, create HMACs, inspect security headers, and check subresource integrity — handy for developers and anyone protecting their data.

They suit developers, students, and security-conscious users. Because everything runs in the browser, secrets never leave your device. Combine them with our Developer Tools for building, our Utility Tools for encoding, and our Domain Tools to review server configuration.
