UUID Generator

A UUID (Universally Unique Identifier) is a 128-bit number that's basically guaranteed to be unique. Like, REALLY unique. We're talking "generate one every nanosecond for the next 100 years and you still won't get a duplicate" kind of unique.

Format: 8-4-4-4-12 hexadecimal digits
Example: 550e8400-e29b-41d4-a716-446655440000

This generator creates Version 4 UUIDs, which are randomly generated. No central server, no coordination needed. Just pure chaos that somehow works.

Use them for:

• Database primary keys (when auto-increment feels too predictable)
• Session identifiers (because "session123" is not a great idea)
• File names (when "final_v2_FINAL_REAL_FINAL.docx" isn't cutting it)
• Anything that needs a unique ID without asking permission from a central authority

The math says you'd need to generate 1 billion UUIDs per second for about 86 years to have a 50% chance of a collision. So yeah, you're probably fine.
