How to Determine if AES-256 Bit Encryption is Used in a Session

Objective

Determining if AES-256 Bit Encryption is used in a session.

Applies To

  • Video API 
  • Encryption
  • AES-256

Procedure

  1. To validate AES-256 is used in the session, check with webrtc internals logs. For example in Chrome, go to chrome://webrtc-internals before connecting the session. 
  2. Download the webrtc internals dump and you will see that the media encryption used is AES-256.
