Frequently asked questions

Quick answers about propagation, resolvers, and how this checker works.

Do these generators send my data to a server? +

Most Phase 4 tools run in your browser. Password hashing is processed on the server only when you submit the hash form.

Is MD5 secure for passwords? +

No. MD5 is for compatibility checksums. Use bcrypt/Argon2id for password hashing.

Can I rely on RAID math alone? +

The calculator is educational math — verify with your storage vendor docs.

Where is notepad data stored? +

Only in your browser localStorage on this device.

Why warn on URL opener? +

Opening many URLs can be abused; we warn and require explicit user-entered lists.
