git-crypt VS git-filter-repo

And occasionally to encrypt files, or receive encrypted files.

These are practical things which are non-theoretical.

Depends on how careful you are or want to be, with your private key. My house key isn't the same as my car key isn't the same as my bike key.

Alright fair, bad example. What I was grumbling about was more the lack of any clear communication that you've been auto-opted-in to a feature on protonmail, with no user interface signal indicating so, leading to confusion for a couple months like in TFA. I definitely wasn't casting shade on the opengpg keyserver, nor protonmail. It's the "hey! I didn't check a box for this, and it's not mentioned anywhere in the protonmail docs" hidden functionality which could do with some clarification.

I'm a forgetful creature. If I intentionally put my key on a keyserver, because I'm playing around and learning about PGP, will I make the connection between it and protonmail a few months down the line if I move my email account to them? Unlikely.

It's a nice automated feature. Protonmail-to-protonmail e2e encryption makes a lot of sense. I just think protonmail-to-non-protonmail e2e needs a tooltip in the UI, and the option to opt out, potentially with the ability to opt out for specific email addresses. I wouldn't at all assume it would be on by default even IF I've been actively using PGP in my email clients, because it's something you usually have to manually set up yourself, very explicitly. That, and 99.9% of emails are plaintext.

Anyhoo, one thing I forgot which kind of negates the "what if I have multiple encryption keys tied to my email" is the fact that the opengpg keyserver does tie 1 email address to 1 key so you can't publish multiple encryption keys, fair enough. Git-crypt and file encryption, I set my associated email address to use +tags eg [email protected], so as far as protonmail etc are concerned there's only one key per logical email address.

Apart from a few exceptions (like ansible for example, which supports native encryption), we moved away from encrypted secrets in git repos and use external things, depending on the platform (like parameter store / secrets manager for AWS or keyvault for Azure - both of these do track changes, btw), so I haven't looked for quite a while. Back in ye olden days we used https://github.com/AGWA/git-crypt which worked quite nicely, but the key management is cumbersome and it's based on GPG, which in itself is a bit of a light redish flag these days.

How about encryption?

https://github.com/AGWA/git-crypt has been solid for me

You might want to check out git-crypt. It allows you to encrypt and decrypt files in a git repo without needing an external account, and supports .env files. That said, trying your hand at making one as a personal project could be a fun and rewarding experience!

I hesitate to append this but one option I have seen thrown around and also debated is git-crypt [1] There are many caveats to doing this as any integrations that would need to read the file contents would also need to be able to decrypt the files so this may not be entirely useful and may add many levels of complexity and fragility.

The most interesting approach I've seen for this is https://github.com/AGWA/git-crypt

Here is the Makefile.

I use git-crypt to encrypt files in git repositories quite a lot and I find that it doesn't work on RHEL-based distros because of some missing or out-of-date library. I need to build a statically linked binary.

Store the Secrets in a repo using gitcrypt or another encryption tool.

Consider using git-crypt for transparent encryption instead.

Hit Ctrl-C before proceeding to abort, then use an alternative filtering tool such as 'git filter-repo' (https://github.com/newren/git-filter-repo/) instead.

Yup you need https://github.com/newren/git-filter-repo Take a look at https://github.com/newren/git-filter-repo/blob/main/INSTALL.md for instructions

git filter-repo: a third-party command actually, as a replacement to Git's own filter-branch, that allows rewriting the whole history of a repository to remove a mistakenly added file, or help extract part of the repository to another.

I needed to archive some old repositories into a monorepo and of course I gave myself the requirement of maintaining git history, in some way. I tried a couple of solutions but it wasn't until I stumbled upon the git-filter-repo project at https://github.com/newren/git-filter-repo and another article which I've since lost (which was badly documented anyway) that I was able to figure out how to do this.

Git objects are not designed to be changed, they are immutable blobs. This is not a problem if you are making a reader, but is a problem when you want to change things, tools like old git-filter-branch or the newer filter repo abstract all reference updating away for you

Make sure your gitignore is setup right (GitHub has a repo of good defaults). If you messed that up, you could rewrite git history to remove the big stuff. Use git-filter-repo. Not sure how that works for LFS.

I personally prefer git-bfg ( https://rtyley.github.io/bfg-repo-cleaner/ ) ... though git-filter-repo ( https://github.com/newren/git-filter-repo ) is quite popular. The difference for me was that git-bfg is JVM based and my work machine has Java on it while git-filter-repo is python based... and my work machine is without python.
