Encrypting git repositories in Eclipse [message #1769706]

Remote Git repos can be encrypted with git-crypt.

Git-crypt uses gitattributes to specify its own git filter and diff function, eg:

secure-dir/**   filter=git-crypt diff=git-crypt]

This works transparently in EGit/JGit except that the git-crypt diff function is not being called when comparing file versions (see fig. 1).

Is there a way to insert the git-crypt diff function into the Eclipse pipeline, so it is called before the EGit/JGit diff function?

Interesting. That's the normal Eclipse compare editor. I don't think the diff setting from .gitattributes should apply at all: EGit just gets the blob from the commit's tree and feeds that to the Eclipse compare framework.

It appears that when the blob is gotten, EGit/JGit should apply the filter from .gitattributes but doesn't?

In the screenshot I see that the file is at /archive/docs. So surely your .gitattributes entry is not "secure-dir/**" for this case. What is the exact pattern, and where is the .gitattributes file itself located?
