They are certainly useful for creating unique id's, but for randomness? No.
- the_mitsuhiko 8y agoAnyone who has used UUIDs should be aware that there are different UUIDs. In fact, UUID3,4 and 5 are all generally random. UUID4 depending on the quality of your RNG and 3 and 5 depending on the quality of the input data.
