🔒Encryption and recovery happen
entirely in your browser: neither the secret nor the

contain a web address.
A single sheet, protected by a passphrase. You may
print several copies and keep them in different places: each
is useless without the passphrase.
⚠To check before generating
You can fix these points, or generate the sheet anyway.
The secret is spread across several sheets. A defined number
must be gathered to reconstruct it:
no passphrase is needed. A single sheet reveals
absolutely nothing.
Scan or paste one sheet's data. Cryptyrus automatically
recognises whether it is a single sheet or a
split, and asks for what's missing.
