Encryption
|
The goTenna App by default has elliptic curve 384-bit encryption for one-to-one and group chats. Broadcast messages are not encrypted natively, but encryption can be added to broadcast messages. This will make broadcast messages (including PLI updates) AES 256 encrypted. |
Creating and Sharing Encryption Keys
To create an encryption key: Navigate to the encryption menu by selecting “Encryption” from the main menu. Select the “+” icon to create or acquire a new encryption key.
Create Key
On the encryption page, tap the “plus” and select “Generate new key.”
-
- The first step to creating a key is to name the key.
- After naming the key, you have to choose between sharing via Broadcast chat or QR code.
- Whichever option you choose, you must go to step 2, Validate Key (2 of 2) to share the validation key via QR code or alphanumeric pin.
- If PIN is selected, a PIN will appear on the screen to be read to all team members for input on their devices. Select Done once all team members have validated the key.
Layered Encryption
You may set up as many encryption keys as you’d like but you can only have one active at a time.
Troubleshooting
Problem 1: I can’t see anyone’s messages or PLI information
Solution:
- Ensure that users are on the same encryption key
- Have users test transmissions without encryption to ensure there is not another setting interfering with this function
