# Adding a Matrix proof
|
||
|
|
|
||
|
|
Let's add a decentralized Matrix proof to your OpenPGP keys.
|
||

|
||
|
|
|
||
|
|
### Sending a proof message
|
||
|
|
|
||
|
|
After logging in into Matrix, join the
|
||
|
|
[#doipver:matrix.org](https://matrix.to/#/#doipver:matrix.org) room and send the
|
||
|
|
following message (make sure to replace FINGERPRINT)
|
||
|
|
|
||
|
|
```
|
||
|
|
[Verifying my OpenPGP key: openpgp4fpr:FINGERPRINT]
|
||
|
|
```
|
||
|
|
|
||
|
|
Click on "View Source" for that message, you should now see the value for
|
||
|
|
`room_id` and `event_id`.
|
||
|
|
|
||
|
|
The value for `room_id` should be `!dBfQZxCoGVmSTujfiv:matrix.org`. The value
|
||
|
|
for `event_id` is unique to your message.
|
||
|
|
|
||
|
|
If your Matrix client does not support "View Source", choose "Share" or
|
||
|
|
"Permalink". The URL obtained should look like this:
|
||
|
|
|
||
|
|
```
|
||
|
|
https://matrix.to/#/ROOM_ID/EVENT_ID?via=...
|
||
|
|
```
|
||
|
|
|
||
|
|
### Update the PGP key
|
||
|
|
|
||
|
|
First, edit the key (make sure to replace FINGERPRINT):
|
||
|
|
|
||
|
|
```
|
||
|
|
gpg --edit-key FINGERPRINT
|
||
|
|
```
|
||
|
|
|
||
|
|
Add a new notation:
|
||
|
|
|
||
|
|
```
|
||
|
|
notation
|
||
|
|
```
|
||
|
|
|
||
|
|
Enter the notation (make sure to replace USER_ID, ROOM_ID, EVENT_ID):
|
||
|
|
|
||
|
|
```
|
||
|
|
proof@metacode.biz=matrix:u/USER_ID?org.keyoxide.r=ROOM_ID&org.keyoxide.e=EVENT_ID
|
||
|
|
```
|
||
|
|
|
||
|
|
So, for user `@foo:matrix.org`, this would be:
|
||
|
|
|
||
|
|
```
|
||
|
|
proof@metacode.biz=matrix:u/@foo:matrix.org?org.keyoxide.r=!dBfQZxCoGVmSTujfiv:matrix.org&org.keyoxide.e=$3dVX1nv3lmwnKxc0mgto_Sf-REVr45Z6G7LWLWal10w
|
||
|
|
```
|
||
|
|
|
||
|
|
Save the key:
|
||
|
|
|
||
|
|
```
|
||
|
|
save
|
||
|
|
```
|
||
|
|
|
||
|
|
Upload the key to WKD or use the following command to upload the key to
|
||
|
|
[keys.openpgp.org](https://keys.openpgp.org) (make sure to replace FINGERPRINT):
|
||
|
|
|
||
|
|
```
|
||
|
|
gpg --keyserver hkps://keys.openpgp.org --send-keys FINGERPRINT
|
||
|
|
```
|
||
|
|
|
||
|
|
And you're done! Reload your profile page, it should now show a Matrix account.
