Integration

Outlook

Seal a sentence or a file from the compose window. Your message carries a link. The protected part never sits in a mailbox.

Planned

Planned. The Outlook integration is not built yet. This page shows how it will work. Names and logos belong to their owners, and gotin is not affiliated with or endorsed by them.

Use case

The one sentence that should not sit in a mailbox.

Ana has to send a client new account details. The greeting can travel as email. The account number should not sit in two mailboxes for years.

STEP 01

Open the gotin pane

A button in the compose window opens it beside your message.

STEP 02

Type the text or pick the file in the pane

Not in the email itself. Outlook saves a draft to your mail server while you write, so anything typed there has already left your device.

STEP 03

The email gets a link

The text or file is sealed on your device. Your message carries the link.

STEP 04

Dana opens it

With a passkey on her own device, or with her team key if her firm uses gotin.

Who holds what

The mailbox gets the message. Not the protected part.

Their toolOutlook and the mail servers

Every mailbox the message passes through.

Crosses

What Outlook and the mail servers hold

  • Your greeting and the rest of the message
  • A link
  • The time the email was sent
Stopped

What they never hold

  • The protected text or file
  • A draft of it
  • A key that opens it
gotinThe gotin pane, in your browser

The protected part is sealed here. Only the sealed copy leaves, and it goes to gotin, not to the mailbox.

Sending

Two ways to protect what you send.

Both use the same published algorithms. The choice is how the recipient opens the file.

Method 1

Passkey

For anyone. The recipient opens the link with a passkey on their own device. The first open binds the link to that passkey.

Passkey secret + XChaCha20-Poly1305
Method 2

Recipient key

For a recipient who uses gotin. The file is sealed to their team key, so there is nothing to share but the link.

X-Wing (ML-KEM-768 + X25519) + XChaCha20-Poly1305
How it is built

A page from gotin, inside Outlook.

Build

The gotin frame

The pane is a page from gotin shown inside Outlook. Your keys stay in it, in your browser.

Separation

Outlook's script stays outside

Outlook needs its own script to add a button. That script runs in an outer page. The page that holds your keys never loads it.

Order

After sending

Planned once sending is built. gotin opens with receiving first.

We build in the order people ask. Tell us, and it moves up the list.
