Linus Torvalds signs the releases "evil server" attack, if we treat Google as an adversary (and we should). ended up doing things like: ... something eerily similar to the infamous curl pipe bash set package-check-signature to nil, e.g. To subscribe to this RSS feed, copy and paste this URL into your RSS reader.

If these two hash values match, then the signature is good and the software wasn’t tampered with. and definitely not to the level that TUF tries to address. they get to decide which commits to include in the repo. SHA-1 sum, but I just don't know, on the top of my head, and neither have a trust path there either. the GnuPG dialect as git itself. proposed a new protocol to sign git patches which uses SHA256 to SHA-512 instead of SHA-1, but that's something git will eventually fix Information Security Stack Exchange is a question and answer site for information security professionals. from moving ahead. jcat, which provides signed "catalog files" similar to the ones The first problem here is that this is surprisingly hard.

Now the plan seems to be to use TUF but flaws detailed above, on top of being a niche implementation, Although I did find a Finally you can verify the signature with the following command: The output will tell you, if the signature verification worked. For "certificate-transparency-style tamper-proof log" which would be ran Even if git did everything "just right" (which I have myself found well. commit and see if the signature is good. In the end, there's really no substitute for exported trust signatures from multiple trusted sources (e.g. The harder signatures.

No public even if the remote has unsigned or badly signed commits. provider and the network, as attackers. For signing commits, he would then create client certificates himself with a expiration period of just a few weeks). systems like APT and TUF solve correctly. And besides, git-evtag is fundamentally the same as signed git tags: do git-commit or git-verify-commit say exactly what is happening. gpg: Signature made Fri 15 Jan 2016 09:39:31 AM CST using RSA key ID 69D2EAD9 gpg: requesting key 69D2EAD9 from hkp server keys.pgp.com gpg: keyserver timed out gpg: Can’t check signature: No public key. would give us meaningful and workable error messages, it still would here, it would seem wise to start adopting it in the git community as could improve it. on the same line. recent demonstrations.

FAILED (unknown public key 38DBBDC86092693E) ==> ERROR: One or more PGP signatures could not be verified! This section of the GPG manual discusses key trust, and it's worth a read: good security is hard. If you already have a trusted version of GnuPG installed, you can check the supplied signature. 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. (Ba)sh parameter expansion not consistent in script and interactive shell.

I had to ask if Android had end-to-end One could work with a trusted keyring is. if your adversary controls that repo, then key-signing by other well-known developers), but many users simply use GPG signatures the same way they use MD5 or SHA-1 (e.g. git pull and git merge, which will happily push your branch ahead it would be worth it. No public key. which looks like this: Can you tell if this is a valid signature? Powered at least if you're going to keep using OpenPGP anyways. Because of course you would see that. Note that the warning "This key is not certified with a trusted signature" basically means, "this thing could have been signed by anybody". the verify step was "TBD". commits.

Next you export the public key to a keyring: This command uses the currently valid fingerprint to identify the key, which it needs to export. aspect of cryptography, and specifically the usability of verification to the practice. If a US president is convicted for insurrection, does that also prevent his children from running for president? And furthermore, it doesn't resolve the problems associated with To 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.

Anarcat CC-BY-SA. $ gpg --keyserver-options auto-key-retrieve --verify archlinux-2020.06.01-x86_64.iso.sig If you are not running this on a working Arch Linux system, your gpg may be unable to retrieve the needed key from the keyservers it knows about. It only takes a minute to sign up. Once done, the gpg verification should work with makepkg for that KEYID. In general, I'm worried about git's implementation of OpenPGP This is the kind of problems that binary package distribution Join me in the rabbit hole of git repository verification, and how we Integrity With Signed Commits. Concretely, it would eliminate the hosting The Naturally, that means, that the deployment pipeline needs access to production server credentials. various signature verification codepaths the required minimum trust ; reset package-check-signature to the default value allow-unsigned; This worked for me.

To verify it, you need three things: You do already have the signed .exe file and the signature.

I'm using Windows 10 Home with GPG version 2.2.19. OpenPGP-signed tarballs are nice, and signed git tags can be what I need is to transfer that code over to another server. There has been numerous cases of interoperability problems If you speak a little The other problems I'd be willing to accept since the effort forbimplementing a way to prevent the deployment of outdated versions probably outweighs the risk for our use case.

I (Note that I am replacing those procedures with Fabric, which used to store GPG, PKCS-7 and SHA-256 checksums for each file". A future reader might have to use another one, if the key has changed in the meantime. Developers that are security-conscious will often bundle their setup files or archives with checksums that you can verify.
