How Generate UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information in computer systems. It's widely used in software development for ensuring unique identifiers across distributed systems.
Our tool supports multiple UUID versions, including v1 (time-based), v3 (name-based using MD5), v4 (random), and v5 (name-based using SHA-1).
Select the desired UUID version, provide necessary inputs if required (like namespace and name for v3 and v5), and click the 'Generate' button to obtain your unique identifier.
While absolute uniqueness can't be guaranteed, the probability of generating duplicate UUIDs is extremely low, making them effectively unique for most applications.
