GUID/UUID Generator

Generate unique identifiers (GUID/UUID) according to UUID version 4 standard

What is a GUID/UUID?

GUID (Globally Unique Identifier) and UUID (Universally Unique Identifier) are standards for generating identifiers with a very high probability of being globally unique.

Main features:

  • Uniqueness: The probability of a match is practically zero
  • Structure: 128-bit value (32 hexadecimal characters)
  • Format: 8-4-4-4-12 character groups (e.g. 550e8400-e29b-41d4-a716-446655440000)
  • Version 4: Random generation (most common variant)

Where are GUID/UUID used?

  • Identification of objects in databases
  • Distributed computing systems
  • Windows registries
  • Web applications and APIs
  • User identification
  • Transaction logs

Our generator creates valid UUID version 4 according to RFC 4122, using a cryptographically secure random number generator.
