Even if this repository is private, it is a security risk to just publish them into the world wide web. What are the drawbacks of storing them separately? These files are not version controlled. Filenames change, locations change, passwords change from time to time, some new information appears, other is removed. And you can not tell for sure which version of the configuration file was used with each commit. When building the automated deployment system there will be one extra step: download and place these secret-configuration files where they need to be. So you have to maintain an extra secure server, where everything is stored. How does git-secret solve these problems? git-secret encrypts files and stores them inside the git repository, so you will have all the changes for every commit. git-secret doesn’t require any other deploy operations rather than git secret reveal, so it will automatically decrypt all the required files. What is git-secret? git-secret is a bash tool to store your private data inside a git repo. How’s that? Basically, it just encrypts, using gpg, the tracked files with the public keys of all the users that you trust. So everyone of them can decrypt these files using only their personal secret key. Why deal with all this private-public keys stuff? Well, to make it easier for everyone to manage access rights. There are no passwords that change. When someone is out - just delete his public key, reencrypt the files, and he won’t be able to decrypt secrets anymore. Find out more: https://sobolevn.github.io/git-secret/ ``` ## Robin H.

I've wondered if storing metadata about the objects in notes might improve matters: - a clearsigned block with verifiable readable data (eg who in a team can access) - an encrypted block with the inner key (nice side effect that this separates versioning of the wrapped inner key from the versioning of the object). This also a nice property that when you revoke/remove an outer (user) key, can know implicitly the old secrets they had access to (which should probably be rotated, as you don't know if they have a copy of them outside of the system). Yes, I'm aware of other system's like Hashicorp's Vault, but do appreciate the simplicity of git-secret, pass [1], pwstore [2] and other simpler tools. [1] https://www.passwordstore.org/ [2] https://github.com/formorer/pwstore It's at least as old as the Git history indicates, possibly older, I don't know if the Git history included a full conversion of SVN history. -- Robin Hugh Johnson Gentoo Linux: Developer, Infrastructure Lead, Foundation Trustee E-Mail : robbat2@gentoo.org GnuPG FP : 11ACBA4F 4778E3F6 E4EDF38E B27B944E 34884E85 ``` ## Никита Соболев, 2016-03-14 07:22 Subject: Re: git-secret - store your private data inside a repository Message-ID: URL: https://gitlist.dev/e/CAO_bL1y8tp5%2BNKdPqpwqJvX2xWY6Wg1oZbnRTKAVjKrg94b3BA%40mail.gmail.com In-Reply-To: ``` Robin, thank you for interest. I have not seen 'pwstore' before, but I don't like the idea to store headers inside the file. As it might break things. But I love the idea of groups and access rights. It is a direction I would like to follow. Also I like your suggestion about the key's white-list. That's a feature I have already planed for the future releases. I guess 'pass' was made for a single user. But 'git-secret' was made for multiple people. So you can invite someone to share your encrypted files and easily remove them. Also, I have noticed that 'pass' stores the encrypted files in the separate repository. Well, that's an arguable way to go. It has some benefits like: code-repository and pass-repository may have different access rights, different people involved. But there's a lack in consistency when you have two separate repositories. 2016-03-14 2:52 GMT+03:00 Robin H.

It's also that it aims to be a simple secret storage tool (no random blobs), with an optional Git backing (simply making the directory versioned), rather than secret-storage-for-any-git-repo. I included pass also because it has some nice UX (IMO). -- Robin Hugh Johnson Gentoo Linux: Developer, Infrastructure Lead, Foundation Trustee E-Mail : robbat2@gentoo.org GnuPG FP : 11ACBA4F 4778E3F6 E4EDF38E B27B944E 34884E85 ```
