Frequently Asked Questions

What is HMAC?

HMAC (Hash-based Message Authentication Code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. It's used to verify both the data integrity and authenticity of a message.

Which hash algorithm should I use?

SHA-256 is recommended for most applications as it provides a good balance of security and performance. Use SHA-384 or SHA-512 for applications requiring higher security levels.

Is this tool secure?

Yes, all calculations are performed locally in your browser using the Web Crypto API. Your message and secret key never leave your device.

What's the difference between Hex and Base64?

Hexadecimal (Hex) and Base64 are different ways to represent binary data. Hex is longer but uses only numbers 0-9 and letters A-F. Base64 is more compact but uses a larger character set.
