Open a Keep package

Somebody made this for you with OBSCURA Keep: their papers, sealed under a passphrase, with a letter. It opens here, in your browser. There is no account to make and nothing to pay, and nothing in the package is sent anywhere.

or drop the file here. It is a file ending in .okeep.

What this page does

It reads a package and nothing else: it cannot change one, make one or keep one. The passphrase is stretched with Argon2id and the package opened with AES-256-GCM, in this tab, and the package is gone from memory when you close it or the tab. A part that has been changed or damaged fails its check and is reported rather than shown. To make packages, or to keep your own papers this way, see OBSCURA Keep; what it protects against is on its threat model.
