There are a few strategies to rectify this... I hope that by sharing my experience, someone else will find Curve25519 a little more approachable, too! Betrusted is a secure and private communications system. It gives users an evidence-based reason to believe that private matters are kept private. Betrusted is more than just an app, and more than just a gadget – it is a co-designed hardware + software solution that provides safe defaults for everyday users. It’s also open source, empowering advanced users to analyze, extend and explore this secure mobile computer.
