The CRUX Linux distribution switched from MD5 hashs to signify.
Compared to GPG this is _very_ small and easy, and only meant for
exactly this purpose. Mind you, i for one could live with
improved OpenSSL tools -- they have the theoretical capability to
cover TLS / S/MIME / file checksumming and more, even multiple of
the latter in batch. Unfortunately that is not true in practice.
(And i won't be the one who implements it.)
Leah Neukirchen maintains up-to-date portable code on github, not
only of that.
Please let me, as a non-mathematician non-cryptographer, wonder
how unsafe MD5 for the purpose of file-checksumming really is.
