About This UUID Generator
This tool generates UUIDs (Universally Unique Identifiers) according to RFC 4122. UUIDs are designed to be unique across both space and time, with an extremely low probability of duplication. They are commonly used in software development for database keys, session identifiers, and other scenarios requiring unique values.
