UUID v4 generator

A UUID v4 generator is a tool used to generate version 4 universally unique identifiers (UUIDs). UUIDs are standardized identifiers that are guaranteed to be unique across time and space, making them useful for identifying and referencing entities in distributed systems or databases without centralized coordination. Version 4 UUIDs are generated using random or pseudo-random numbers, resulting in a high probability of uniqueness. UUID v4 generators typically produce 128-bit hexadecimal strings that conform to the UUID version 4 format, ensuring they are suitable for use in various applications where uniqueness is essential.
