The Perl 5 module UUID::Tiny is a lightweight, low dependency Pure Perl module for UUID creation and testing. This module provides the creation of version 1 time based UUIDs (using random multicast MAC addresses), version 3 MD5 based UUIDs, version 4 random UUIDs, and version 5 SHA-1 based UUIDs. ATTENTION! UUID::Tiny uses Perl's rand() to create the basic random numbers, so the created v4 UUIDs are not cryptographically strong!
