libuuid1 - 2.36.1-8+deb11u1pureos1 main

The libuuid library generates and parses 128-bit Universally Unique
IDs (UUIDs). A UUID is an identifier that is unique within the space
of all such identifiers across both space and time. It can be used for
multiple purposes, from tagging objects with an extremely short lifetime
to reliably identifying very persistent objects across a network.
