It's exceedingly hard to write good cryptography.

It's even harder to make it usable for its intended use case.

It's even harder to make it fit a wide range of use cases and threat models. (Do you care about metadata resistance? Cwtch is better than Signal for that.)

This is not a space you can just meander into and give it a good college try. You have to be deliberate, meticulous, and highly self-critical to succeed.
