One of the complaints that I have heard on this subreddit is that it is hard to design and implement cryptographic software that is misuse resistant--and I am not sure if that is harder than implementing cryptographic software that is secure.
When I asked similiar questions people admitted I can study libraries such as LibSodium as an easy-to-use crypto library.
What are the techniques to design such misuse-resistant crypto software--broken down into holistic steps?
I thank all in advance for all responses.
