Our whole cloud infrastructure was accidentally deleted by an erroneous deployment script. We have tape backups but they are encrypted using a very secure passphrase and it turns out it was stored in a git repository in the cloud. We were able to construct a complete git log of the repository since a developer had setup an unauthorized bot that was quietly tweeting all commits to the world. The log is attached as gitlog.txt.
Can you help us recover the key?
