Set AES encryption and a passphrase for SRT

You can configure your Secure Reliable Transport (SRT) streams to use 128 bits, 192 bits, or 256 bits AES encryption using the Admin panel. You can also assign the SRT stream an alphanumeric passphrase if required. The encryption and passphrase settings on the SRT encoder sending the stream must match the settings on the SRT decoder receiving the stream.

The encryption key length is negotiated between the source and destination devices. The key length of the sender is used to determine the key length that is eventually used to secure the connection, and the receiver obtains the key length from the sender. As long as the passphrases match, the key length will be negotiated.

Set up AES encryption and a passphrase for an SRT stream using the Admin panel

  1. Log in to the Admin panel as admin, see Connect to the Admin panel.
  1. From the Channel(s) menu, select the channel with the SRT stream to configure and click Streaming. The Streaming configuration page opens.
  2. Click the arrowhead beside the SRT stream name to reveal the stream settings. In this example, the name of the SRT stream is Stream 1.
  3. Check Encryption and choose the Key length.
  4. In the Passphrase field, enter the passphrase using alphanumeric characters (if required). The password must be a minimum of 10 characters and maximum of 79 characters.
  5. Click Apply.
