How it works
KadiTools uses crypto.randomUUID() where available, and otherwise builds a version-4 UUID from crypto.getRandomValues(). A v4 UUID has 122 random bits.
Security notes
UUIDs are good unique identifiers, but they are not designed as secrets. For access tokens or API keys, use the Secure Token Generator.
FAQ
Are collisions possible?
In theory yes, in practice the odds are astronomically small, even across billions of IDs.
