git pull has two problems:

It merges upstream changes by default, when it's really more polite to rebase over them, unless your collaborators enjoy a commit graph that looks like bedhead.
It only updates the branch you're currently on, which means git push will shout at you for being behind on branches you don't particularly care about right now.

Solve them once and for all.

git-crypt enables transparent encryption and decryption of files in a git repository. Files which you choose to protect are encrypted when committed, and decrypted when checked out. git-crypt lets you freely share a repository containing a mix of public and private content. git-crypt gracefully degrades, so developers without the secret key can still clone and commit to a repository with encrypted files. This lets you store your secret material (such as keys or passwords) in the same repository as your code, without requiring you to lock down your entire repository.
