Seve_py :vim: :python:AFAIK, there's only one existing Vim plugin for buffer checksums, and it's quite old, relying heavily on terminal tools.

oxoMade good progress on my file integrity tools lately.Calc-sum updates sha3-512 checksums in a hash-list. When executing my scripts I can check the file integrity with check-sum while running. This is a security measure; sometimes I type in a file by accident without noticing. But now check-sum holds the script if the file has changed and the integrity check fails. For remote files this can of course also work as an extra security tool.<a href="https://codeberg.org/oxo/tool" rel="nofollow noopener" target="_blank">https://codeberg.org/oxo/tool</a><a href="https://qoto.org/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#linux</a> <a href="https://qoto.org/tags/terminal" class="mention hashtag" rel="nofollow noopener" target="_blank">#terminal</a> <a href="https://qoto.org/tags/commandline" class="mention hashtag" rel="nofollow noopener" target="_blank">#commandline</a> <a href="https://qoto.org/tags/sha3" class="mention hashtag" rel="nofollow noopener" target="_blank">#sha3</a> <a href="https://qoto.org/tags/file" class="mention hashtag" rel="nofollow noopener" target="_blank">#file</a> <a href="https://qoto.org/tags/integrity" class="mention hashtag" rel="nofollow noopener" target="_blank">#integrity</a> <a href="https://qoto.org/tags/security" class="mention hashtag" rel="nofollow noopener" target="_blank">#security</a> <a href="https://qoto.org/tags/checksum" class="mention hashtag" rel="nofollow noopener" target="_blank">#checksum</a> <a href="https://qoto.org/tags/tool" class="mention hashtag" rel="nofollow noopener" target="_blank">#tool</a>
