Does anyone know an good open-source library to learn e2ee?
Most e2ee I come across are not truly end-to-end. Other than Signal, does anyone know any good open source libraries that demonstrates e2ee like station-to-station protocol and ratcheting?
I know about the noise protocol, but I am not sure how good it is as I don't use it: http://www.noiseprotocol.org/
Interestingly the website is not mobile friendly and not using HTTPS.
