What is an HMAC Generator?
An HMAC Generator is a tool that creates a Hash-based Message Authentication Code (HMAC), which is used to verify the integrity and authenticity of data. HMACs combine a cryptographic hash function with a secret key to produce a unique signature for a message or file.

How does it work?
The generator takes your input data and a secret key, then applies a hash function (like SHA-256) to create a fixed-length code. This code changes if the data or the key is altered, ensuring that the message is authentic and hasn’t been tampered with.

What is it used for?
HMACs are widely used in security and software development to:

• Verify the integrity of transmitted data
• Authenticate messages in APIs and webhooks
• Securely sign tokens, cookies, or files
• Prevent unauthorized modifications or forgery

Using an HMAC Generator helps ensure that your data is secure, authentic, and tamper-proof, making it an essential tool for modern web applications and cryptographic systems.
