Frequently asked questions

How strong is the encryption?
AES-256 — the same standard as banking systems; the document is unreadable without the password.
Can a forgotten password be recovered?
No, the service stores no passwords. Keep yours somewhere safe.
How do I share a protected file safely?
Send the password via a separate channel — a call or a different messenger.
