A CLOSER LOOKThe details behind
The details behind
the result.
Understand the format, the calculation, and what to look for.
UUID versions
v1/v6 contain time and node information; v3/v5 hash a namespace and name; v4 is random; v7 is time-sortable; v8 is random application-defined space.
Formats
Canonical is the standard hyphenated string. Compact, URN and braces change only presentation, not the UUID value.
Passwords
Every selected class is represented, then the result is shuffled. Secrets are never persisted.
