Yes, just compute the sha256 checksums and compare. I had been meaning to add a version command to encpass.sh for a while now and just hadn't made time for it. Your comment was the impetus I needed, so I've gone ahead and added support for computing the sha256 checksums of encpass.sh and any extension and also displaying the tag version.

I've cut a new release for the version command, v4.1.0. See the release notes here for additional details -> https://github.com/plyint/encpass.sh/releases/tag/v4.1.0
