Document how to undo git-crypt, e.g. remove item from .gitattributes

[dazza-codes]

There is documentation about how to apply git-crypt, but nothing to un-apply it. What happens when a file that is encrypted, with an entry in the .gitattributes file to use the git-crypt filters, and a new commit removes the .gitattributes entry? How is a file intentionally released from git-crypt filters?

1. Checkout and unlock a copy of the repository.
2. Remove the relevant attribute filter lines.
3. git-add the unlocked state of the files that were previously encrypted from your working directory and commit them.

FWIW, I found that my PR on GitHub to unencrypt a file showed the .gitattributes changes but the file still looked encrypted. You are able to view the file however and it is unencrypted.

3. `git-add` the unlocked state of the files that were previously encrypted from your working directory and commit them.

Doesn't work. first off git-add is not found... then did git add after unlock, update .gitattribute. File pushed still encrypted on github. (locally it's not encrypted, but if I clone again it would be)

Had same issue. Only next tricky works for me (problem file is a foo.py in this example):

• cat foo.py > spam.py
• git add spam.py; git commit -m "added version without enc"; git push
• delete foo.py mention from .gitattributes file
• git rm foo.py
• git add .gitattributes.py; git commit -m "delete encrypted version"; git push
• git mv spam.py foo.py; git commit -m "rename version without encyption"; git push

To avoid multiple commits and moved around files the following worked for me:

• checkout and unlock repo
• remove [filter "git-crypt"] and [diff "git-crypt"] sections from .git/config
• remove corresponding lines in .gitattributes and add changes to the index
• remove symmetric key (if any) rm .git/git-crypt -r
• remove (encrypted) path only from the index git rm --cached foobar
• re-add local (unencrypted) path to the index git add foobar
• commit and push the changes

I tried @ilia-tsyplenkov and @hvhaugwitz workarounds but my file is style encrypted and considered as binary on Github entreprise.

My problem with their solutions is that .gitattributes has already been modified before.
