Understanding UUID Version 4
A Version 4 UUID is a universally unique identifier generated randomly. The format consists of 32 hexadecimal characters grouped in 5 blocks separated by hyphens (8-4-4-4-12 format) for a total of 36 characters.
- Random Generation: v4 UUIDs use cryptographically secure random values (CSPRNG) to ensure that the probability of duplicates is practically zero.
- Format: Example: `f81d4fae-7dec-11d0-a765-00a0c91e6bf6`. The digit indicating the version is always `4` at the start of the 3rd block.
- Security: All generations are computed in-memory on the client browser. No tracking or logging is done.
