What This Tool Does
UUID generation: Creates version 4 (random) UUIDs—128-bit identifiers designed to be unique across space and time. Each UUID has 32 hexadecimal digits in 5 hyphen-separated groups.
Structure: Format is 8-4-4-4-12 (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx) where each x is a hexadecimal digit (0-9, a-f).
Uniqueness: Uses cryptographically strong random values for extremely low collision probability. Suitable for database keys, distributed systems, and unique IDs.
Version 4: Random UUID variant—the most common type. No timestamps or MAC addresses, ideal for web apps and privacy-conscious systems.
