About ClientCipher

ClientCipher is a free online tool that generates mock client ID numbers — prefixed codes, hex strings, UUID-style values and plain numerics — for anyone who needs realistic-looking customer identifiers without touching real customer data.

Why it exists

Developers building CRMs, billing tools and admin panels, technical writers documenting APIs, and product teams preparing demos all need the same thing: believable client identifiers that are safe to use anywhere. ClientCipher produces a clean, structured, deduplicated batch in seconds.

How it works

The tool is a single JavaScript file running in your browser. It draws randomness from crypto.getRandomValues(), assembles IDs in your chosen format, and removes duplicates within the batch. No account, no backend, no tracking — 100% client-side.

What it is not

ClientCipher is not a customer database, not an identity service, and not a source of real identifiers. Every ID it produces is randomly generated mock data with no uniqueness guarantee beyond the current batch. The honest-limits box on the generator explains the boundaries.
