HMAC Generator
HMAC (Keyed-Hash Message Authentication Code) offers a secure method for message authentication using cryptographic hash functions. It combines a secret key with the message data, applies a hash function, and produces a hash that can be used to verify the integrity and authenticity of the message.

History and How to Use
HMAC was introduced in 1996 and has since become a standard for message authentication in various cryptographic protocols and systems. Its design ensures that both the message integrity and authenticity are verified, making it significantly harder for attackers to tamper with or forge messages.
How to Use:
- Enter a secret key and the message you wish to authenticate.
- Select the desired hash function from the dropdown menu.
- Click "Generate HMAC" to produce the hash code.
- Use the "Copy" button to copy the HMAC to your clipboard.
Common Use Cases:
- API Security: HMAC is commonly used to secure API calls, ensuring that the requestor is authenticated and the message has not been altered.
- Data Integrity: Verifying that data transferred over networks or stored in databases is genuine and untampered.
- Secure File Transfer: HMACs can authenticate the integrity and authenticity of files shared over insecure networks.
- Cryptographic Protocols: Many protocols use HMAC for functions like key exchange and message verification.
