.. zephyr:code-sample:: uuid
   :name: UUID

   Manipulate UUID v4 and v5 compliant with IETF RFC 9562.

Overview
********

This sample app demonstrates the use of the :c:group:`uuid` utilities to generate and manipulate
UUIDs accordingly to IETF RFC 9562.

The following functionality is demonstrated:

- UUIDv4 generation
- UUIDv5 generation from namespace and data
- UUID conversion from/to string and to base64 and base64 URL safe formats

Requirements
************

This sample relies on the following modules:

- MbedTLS for the UUIDv5 hash functions
- Base64 for the base64 encoding of UUIDs
- Entropy source for the pseudo-random generation of UUIDv4
