Security Tools
Our Security tools give software engineers, security analysts, and DevOps personnel instant access to cryptographic functions and token inspection utilities without compromising sensitive data privacy. In web development and systems administration, computing checksums, validating payload signatures, and inspecting authentication tokens like JSON Web Tokens (JWT) are routine tasks. Traditional online converters often transmit inputs to remote backends, posing severe security risks when handling API secrets, password hashes, or bearer tokens. At Codify Tools, every cryptographic algorithm—including MD5, SHA-1, SHA-256, SHA-512 hashing, and JWT signature decoding—is computed entirely within your web browser using HTML5 Web Crypto APIs and JavaScript. Your confidential strings, secrets, and authorization headers never touch external servers or databases. Use these free, fast, and privacy-first security utilities to verify data integrity, debug API authentication workflows, and inspect cryptographic payloads safely from any browser or device.
