Hello Leonid Isaev,
I really like you effort on stronger hashes. I totally aggree with you
that we need those, if we can't have GPG signatures by the maintainers.
Hashes just help in less usecases than GPG signatures, of course, but
Unfortunately I made the experience, that this discussion is useless
here and you rather start helping with GPG signatures for every package.
If you want to put effort into this topic, which I really appreciate,
please directly go for GPG signatures, otherway it will be just a
frustrating discussion for you, sadly.
What I can recommend to you for this is to write to upstream projects
who don't use GPG signatures yet. Explain them why its important and
help them to improve their software release security. I made the
experience that quite a lot of projects did not know about the
importance of GPG or just never looked into it. Just a few refuse to use
GPG, leave that for now.
As additional support you can use the GPGit guides as well as the
automated (same named) GPGit tool: https://github.com/NicoHood/gpgit
It will help new users to understand GPG and provide them an easy to use
tool to get started with GPG within a few minutes. Feedback for this is
I wish you all good luck, dont hesitate to contact me further if you
have any great ideas regarding GPG etc.
