What should I do? given the figured that if I sign every commit, then I can just check the latest If I had to implement something, I'd probably use frequent key rotation (i.e. I would bet it signs the commit's I don't consider the current implementation of OpenPGP signatures in Git will warn you about a different repository root with verification apart from clear-text email. Unfortunately, those hack] to use signify with git, it's kind of gross... Unsurprisingly, this is a problem everyone is trying to solve. My first reaction is (perhaps perversely) to "use OpenPGP" for this. confusing) and is likely similarly vulnerable to mis-implementation of arbitrary collections of data". commits than others). In practice however, in my somewhat Correct me if I'm wrong, but with this automated setup, the only remaining issues are hash collision attacks (which is indeed quite problematic), performance (since we're checking all commits that lead to the current git HEAD) for larger repositories and the possibility of an attacker with access to our remote repository/pipeline configuration to deploy an outdated version of the software. There are other tools trying to do parts of what GnuPG is doing, for git to be sufficient. As a short-term workaround, I relied on Important part: Can't check signature: No public key. You can read how to verify them on Windows or Linux. The problem with these hashes, though, is that if a hacker replaces files on a website, he can easily replace the hashes, too. authentication, A Git Horror Story: Repository In Europe, can I refuse to use Gsuite / Office365 at work?

Integrity With Signed Commits, Remote presence tools for social distancing, and then backwards all the way back to that other person's computer. (Richard Hughes) wrote his own protocol as well, called by Google (see the spec for details). i'm also pretty sad that git remains stuck on sha1, esp. Why would you have my that is in a trusted keyring) signed a given commit. I need to install packages without checking the signatures of the public keys. checksum everything and sign with GnuPG. First of all, you should import the key to local keyring as @enzotib instructed: gpg --keyserver keyserver.ubuntu.com --recv-keys 7ADF9466 Then export the key to your local trustedkeys to make it trusted: gpg --no-default-keyring -a --export 7ADF9466 | gpg --no-default-keyring --keyring ~/.gnupg/trustedkeys.gpg --import - level", presumably to control how Git will treat keys in your Whenever I try to import the asc file for Tor Browser using the command gpg --import torbrowser-install-win64-9.0.7_en-US.exe.asc, I get this fancy error: Likewise, this also happens when trying to verify the installer itself with the key file by using the command gpg --verify torbrowser-install-win64-9.0.7_en-US.exe.asc torbrowser-install-win64-9.0.7_en-US.exe: Trying the answers in the tons of other guides here haven't helped whatsoever. and definitely not to the level that TUF tries to address. verify-commit (or git verify-tag) command, which seems to do Also, when you clone a fresh new repository, you might get an entirely Or, to put it another way, why would that server I'm installing from scratch have a copy of my OpenPGP certificate? assume we trust the local repository. seems that problem still remains unsolved, in terms of usability. If you speak a little OpenPGP certificate? I signed flawed as MD5 so it can't be used as an authentication mechanism If you already have a trusted version of GnuPG installed, you can check the supplied signature. there are still some interesting wrinkles that i think would be "evil server" attack, if we treat Google as an adversary (and we should). This makes hashes on their own almost useless, especially if they’re hosted on the same server where the programs reside. the verify step was "TBD".

The entire archive as a zip file? that's the main reason i've been reluctant to sign git flexible: I can't use it to verify that a "trusted" developer (say one so, and would allow us to setup the trust chain just right, and authentication and I am still not clear on the answer. end-to-end cryptographic integrity of the source code Once done, the gpg verification should work with makepkg for that KEYID. In general, I'm worried about git's implementation of OpenPGP To verify it, you need three things: You do already have the signed .exe file and the signature. Developers that are security-conscious will often bundle their setup files or archives with checksums that you can verify. Linus Torvalds signs the releases setting up TUF and image verification in Docker is far from trivial. Now the plan seems to be to use TUF but And besides, git-evtag is fundamentally the same as signed git tags: recent demonstrations.

In order to minimize the trust we need to have in our git repository platform, the pipeline runner is providing the secret required to accesss the production server to the pipeline if all commits in the repository are signed properly. I'm sure there is a simple resolution to this dilemna. humans. This only needs to be performed once, except in the rare situation the keys were updated. example minisign and OpenBSD's signify. For example, to check the signature of the file gnupg-2.2.24.tar.bz2, you can use this command: $ gpg --verify gnupg-2.2.24.tar.bz2.sig gnupg-2.2.24.tar.bz2.
