UUID Generator
Generate UUIDs (Universally Unique Identifiers) in various versions including UUID v1 (time-based) and UUID v4 (random). UUIDs are 128-bit identifiers that are unique across space and time, perfect for database keys, API tokens, and unique identifiers.
v4 (Random): Cryptographically random UUIDs, most common for general use. No ordering.
v1 (Time-based): Includes timestamp and MAC address. Sortable and chronological, useful for database primary keys.
