Share your personal link. Anyone who has it can seal a message for you and send it back as a link, through any app. It is opened here, by a key saved in this browser.

Your personal link
This browser has no key yet. Creating one takes a few milliseconds. The public half goes into your personal link. The secret half is saved in this browser and never leaves it.
Send this link to anyone who should be able to write to you. It is safe to share: it holds only your public key.
Key fingerprint
Read these digits to your contact over a call. If their screen shows different digits, the link was swapped on the way.
Delete the key? Every message sealed for this link becomes unreadable for good, including ones you have not opened yet.
02 Read or write
Open a link
A link opened in this browser is handled automatically. You can also paste one here: a message link is opened with your saved key, and someone else’s personal link opens a form for writing to them.

Sealing for the key with this fingerprint
Only the browser that created this personal link can open what you write. Before sending anything sensitive, check these digits with its owner over a channel you already trust.
This is your own personal link. You can seal a message to yourself to try it out; it can only be opened in this browser.
✓ Sealed
Send this link back to them
Send it through any app. This browser cannot open it again: only the recipient’s saved key can. Some chat apps cut off very long messages; a link that arrives incomplete is refused, never misread.
