What is UUID v4?
- UUID v4 (Universally Unique Identifier, version 4) is a 128-bit identifier generated using random or pseudo-random numbers
- Format:
xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxxwhere x is any hex digit and y is one of 8, 9, a, or b - Uniqueness: With 122 random bits, the probability of a collision is astronomically low (you would need to generate ~2.7 quintillion UUIDs for a 50% chance)
- Cryptographic security: This tool uses
crypto.getRandomValues()for true cryptographic randomness - Common uses: database primary keys, session IDs, API keys, distributed system identifiers, file naming
