Is it possible to generated cryptographically strong uuid values?

zerkms commented 1 year ago

v4, v6, and v7 use crypto/rand as a source of random data (by default).

Hey @elbek, all of the UUIDs supported in this library are built to specifications according to the corresponding RFCs for each version, but the "cryptographic strength" of the UUID depends on the version in use. v4 is probably the strongest because of its generation algorithm, but it can also be subject to certain classes of brute force replication attacks.
