Encrypt calls #14

Open Benjamin-Loison opened 4 months ago

Benjamin-Loison commented 4 months ago

Using GPG for instance but less clear than SMS as SMS are probably less fast than established calls and transmissing GPG encrypted message by call is unclear as as far as I know calls are compressed, possibly in a lossy fashion, for voice.

However, lossy voice encoder may be used so it may not work.

Can be useful when usual means like Signal are not available due to missing 4G. Furthermore, encryption should not add a significant bandwidth usage, hence should be fine. Maybe in more general emulating Internet access with a peer having GSM and Internet access could make sense.

Tracked at Benjamin_Loison/gpg/issues/14.

Maybe can leverage sounds like when type on numpad.
