UUID Validator - Validate UUID Format and Structure

How UUID Validation Works

UUID validation checks the format, structure, and compliance with RFC 4122 standards. It verifies version-specific rules and provides detailed feedback about the UUID.

Format Rules
  • Must be 32 hexadecimal characters
  • Must be separated by hyphens in 8-4-4-4-12 pattern
  • Can be uppercase or lowercase
  • Can optionally be enclosed in braces (GUID format)
Version-Specific Rules
  • Version 1: Time-based with MAC address
  • Version 4: Cryptographically secure random
  • Version 7: Time-ordered with random data
  • Nil UUID: All zeros for testing
