In a world where data security matters more than ever, HMAC (Hash-based Message Authentication Code) is your secret handshake—a way to prove your message is authentic and untampered. I built this HMAC Generator for those moments when you need to sign, verify, or just experiment with cryptographic hashes, without the headache of command lines or complicated libraries.

What makes this tool stand out is its flexibility. Choose your algorithm—SHA256, SHA1, SHA512, or even MD5. Enter your message and secret key, and with a single click, you get a secure HMAC output, ready to use in your API, webhook, or any system that needs a digital signature. Everything happens right in your browser, so your secrets never leave your device.
