UUIDv4 Generator
Generate Universally Unique Identifiers (UUID) version 4.
What is UUIDv4?
Version 4 UUIDs are randomly generated. The total number of possible UUIDv4s is 2^122, or 5.3 x 10^36. The probability of collision is so infinitesimally small that it is considered zero for practical purposes.
Common Mistakes
- Using predictable PRNGs (Pseudo-Random Number Generators) in backend systems instead of the OS entropy pool.
