Voice Call Encryption

[hilmanfitriana19]

hello again, I'm trying to understand the workflow of voice calls encryption on the signal app. After trying to find out on the signal-android project, I was directed to this repository (ringrtc). I then looked for the encrypt module which was most likely used to encrypt the voice call that occurred. I searched the file using the keyword encrypt( which should refer to the existing encryption function using vscode. Here are the results of the existing search.

- src/rffi/src/peer_connection_observer.cc line 166
- src/rust/src/core/crypto.rs line 188
- src/rust/src/core/group_call.rs line 2140

In the three modules, I added a simple log but after it was built and run on Android, the entered log was never called when a voice call was made.

Previously, this method was successfully used to find out and find the encryption function for the part of sending text messages.

What I want to ask is, is it true that the encrypt voice call module is in the crypto.rs file? If not, where is the location of the encrypt module for this voice call and what module in the ringrtc project is the bridge in calling the encrypt module?
