Hash Tools / XOF

cSHAKE256 Hash

Generate a cSHAKE256 hash in the browser. The secondary input acts as a customization string, and leaving it empty falls back to standard SHAKE256-compatible output.

Input

Primary input

Any text is valid here, including blank input. Empty input still produces a deterministic digest.

Customization string

This becomes the cSHAKE customization string. Leave it blank to use the SHAKE256-compatible fallback.

Output

Result

Input bytes 0

Customization bytes 0

Digest bytes 64

Mode SHAKE256 fallback

Ready.

The page always returns 64 bytes of output. If the customization string is empty, the tool behaves like SHAKE256 for the same message.
