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.
