Stream Encryption

Streams can be encrypted using fixed-key AES 256 encryption. There are multiple options for encrypting the stream payload:

• Zixi Feeder output – Zixi Feeder can encrypt outputs using a fixed key (AES 128, AES 192, AES 256) which can be entered into the output settings or automatically generated. In addition, selection of Automatic mode will generate the encryption and exchange it securely between the applications automatically.
• Zixi Broadcaster input – UDP, File and RTMP input streams can be encrypted by Zixi Broadcaster using a fixed key (AES 128, AES 192, AES 256), which can be entered into the input settings or automatically generated.

Zixi Broadcaster can also decrypt contribution streams using a matching key, or securely forward encrypted streams to receivers, without being able to see or analyze the traffic.  

Encrypting an output stream in Zixi Feeder

To encrypt an output stream in Zixi Feeder:

1. In Outputs screen, click +New Output.
2. In the Type field select Push to Broadcaster.
3. Fill in the output details.
4. At the bottom, select the Show all Settings checkbox.
5. Select the Advanced Properties checkbox.
6. In the Encryption Type field, select AES 128, AES 192, AES 256 for fixed key or Automatic for automatically system-generated encryption.
7. If you have selected one of the fixed key encryptions, enter your own encryption key into the Key field or click Generate to generate a key by the system. The exact key should be used to decrypt the stream on the other end.  
   
8. Click OK.
