Our cSHAKE128 Hash Generator provides instant cSHAKE128 hash creation from any text input with real-time processing, customizable output length, and domain separation features. cSHAKE128 is part of the SHA-3 family standardized by NIST and extends SHAKE128 with customization capabilities. Simply type or paste your text, optionally add customization strings, adjust the desired output length, and watch as the cSHAKE128 hash is generated immediately.

What makes this tool special is its support for domain separation through customization strings. You can provide both a function name string (N) and a customization string (S) to ensure distinct outputs for different applications of the same function. When both strings are empty, cSHAKE128 produces the same output as SHAKE128. The tool also features real-time processing and variable output length, with instant updates as you modify any parameter.

cSHAKE128 provides a security strength of 128 bits against all attacks, regardless of the output length. The customization feature makes it particularly useful for applications that need to derive multiple independent functions from a single underlying hash function. This domain separation ensures that outputs from different customizations are independent, even when processing the same input.

Your privacy is completely protected as all hash generation happens locally in your browser. No data is ever sent to external servers or stored anywhere, ensuring your sensitive information remains private. The tool works entirely offline once loaded, making it safe for confidential data processing and perfect for environments with restricted internet access.
