What is KMAC256?
KMAC256 is a cryptographic hash function that produces a fixed-size hash value from variable-length input data. KMAC (Keccak Message Authentication Code) is a variable-output-length PRF and keyed hash function based on Keccak. It provides authentication and integrity with a secret key.
How to Use KMAC256
1. Enter or paste your text into the input field. 2. The KMAC256 hash is calculated instantly as you type. 3. Click "Copy" to copy the hash value to your clipboard. 4. Use the "Clear" button to reset and start over.
When to Use KMAC256
Use KMAC256 when you need authenticated message verification with a secret key, such as API authentication or secure communication protocols.
How KMAC256 Works
KMAC256 combines a secret key with the message using the cSHAKE function. It provides both authentication (proving the message came from someone with the key) and integrity (detecting modifications).
Common Use Cases
- Message authentication
- Key derivation functions
- API authentication
- Secure communications
- Digital signatures
