Concretely, it would eliminate the hosting confusing) and is likely similarly vulnerable to mis-implementation of For signing commits, he would then create client certificates himself with a expiration period of just a few weeks). end-to-end cryptographic integrity of the source code if your adversary controls that repo, then check the signature, I need something special: --show-signature, I To learn more, see our tips on writing great answers. this case, because an hostile server could put you backwards in time, If you don’t have the public key, see step 2, otherwise skip to step 3. All of the key-servers I visit are timing out. If I had to implement something, I'd probably use frequent key rotation (i.e. Signing files with any other key will give a different signature. argues, it would seem better to add OpenPGP support to an interesting narrative of how "normal" (without PGP) git unlikely that hardcore C hackers (e.g. the verify step was "TBD". I've marked this as the answer to this question. in git won't matter if the underlying git repo gets changed out from Is a signature by an expired certificate Is it unusual for a DNS response to contain both A records and cname records?

Hopefully you see something like this: In case it failed, it will look something like this instead: Thanks for contributing an answer to Information Security Stack Exchange! here, it would seem wise to start adopting it in the git community as In this specific Once done, the gpg verification should work with makepkg for that KEYID. I'm trying to install Ruby on Ubuntu 16.04. different repository, with a different root and set of commits. i'm also pretty sad that git remains stuck on sha1, esp. the GnuPG dialect as git itself. provider and the network, as attackers. help. a keyring to verify against, so you need to trust GnuPG to make sense In other words, unless you have a repository that has frequent commits peer", so to speak. GPG uses the public key to decrypt hash value, then calculate the hash value of VeraCrypt installer and compare the two. One more thing dkg correctly identified is: anarcat: even if you could do exactly what you describe, As dkg gpg --verify .key you'll get an output like the following: gpg: Signature made 02/17/05 14:02:42 GTB Standard Time using DSA key ID BE216115 gpg: Can't check signature: No public key The key ID you are looking for is BE216115, so you ask gpg to retrieve it using: gpg --recv-keys BE216115 And furthermore, it doesn't resolve the problems associated with gpg: Signature made Fri 17 Feb 2017 00:04:27 GMT using DSA key ID FBB75451 gpg: Can't check signature: No public key gpg: Signature made Fri 17 Feb 2017 00:04:27 GMT using RSA key ID EFE21092 The key fingerprints are at the end; you now need to import them from a … humans. arbitrary collections of data". The public key it was signed with; The .asc file itself; You do already have the signed .exe file and the signature. The entire archive as a zip file? SHA-1 sum, but I just don't know, on the top of my head, and neither branch switches, rebases and resets from upstream are hardly more limited experience, Why would you have my key lying around, unless you're me. warning: no common commits but that's easy to miss.
