Frequently asked questions

Are these GUIDs secure?

The tool uses browser cryptographic randomness when available, but treat generated values as identifiers, not secrets.

What do D, N, B and P mean?

They are common .NET Guid format specifiers for hyphenated, compact, brace and parenthesis forms.

Should I use random GUIDs as clustered keys?

Review index and insertion behavior for your database; sequential identifiers may be more appropriate in some designs.
