About Security Tools
Security tools are essential for modern software development. Developers frequently need to decode JWT tokens for debugging authentication flows, generate secure passwords for testing, create hash values for data verification, and encode strings for safe transmission. Our security tools handle these tasks efficiently and entirely in your browser. JSON Web Tokens (JWT) are the standard for stateless authentication in web applications. Our JWT Decoder lets you inspect the header, payload, and signature of any JWT token, making it easy to debug authentication issues. The JWT Generator creates tokens for testing purposes. Password generation is a common need — our Password Generator creates strong, cryptographically secure passwords with customizable length, character sets, and complexity options. The Hash Generator supports MD5, SHA-1, SHA-256, and SHA-512 algorithms, useful for checksums, data verification, and fingerprinting. All security tools process data locally in your browser. This is particularly important when working with sensitive tokens, passwords, or cryptographic data — nothing is transmitted to any server. You can safely paste real JWT tokens or generate passwords for production systems without any risk of data exposure.
