You want to make sure you select Signing Key as the key type then paste your public key into the text area.

Now click New SSH Key and you should be presented with a form to add your public key. In the upper-right corner of any page, click your profile photo, click Settings, and select SSH and GPG keys. You can copy your public key to your clipboard using pbcopy pbcopy < ~/.ssh/.pub

The next step is to provide your public key to GitHub to use as part of the verification step. Git config -global tag.gpgsign true Adding your key to Github To sign all commits and tags you can enable the respective gpgsign flags git config -global commit.gpgsign true git commit -S -allow-empty -m 'This should fail'Įrror: Load key '/var/folders/_h/0702xyyn6_56lw_dh373j5240000gp/T//.git_signing_key_tmphdek1f': invalid format? git commit -S -m 'This commit should be signed using my SSH key'Īttempting to sign a commit without adding the key to the agent will result in this error. Although we added the key to the config by referencing the public key, the matching private key is used to sign the commit and must be available to the agent to do so. To create a signed commit you can use the -S flag.

Git config -global user.signingKey 'key::' To enable commit signing you must first add the signing key to your git config (you can omit the -global flag if you want this to apply only to the current repository as opposed to globally). You can then add the generated key to your keychain using ssh-add. The *.pub file is your public key while the other generated file is your private key and should not be shared with any other parties. Using ssh-keygen will generate a new public and private key pair. GitHub recently announced support for SSH signed commits signature verification which takes advantage of the newly added git feature. SSH on the other hand comes preinstalled on most macOS and most Linux distributions making generating key pairs a much simpler process.

This is an excellent alternative mechanism because generating GPG keys is a much more complicated process that requires the user to install the GPG tool suite.

#PBCOPY SSH KEY UPDATE#

Avoid using it unless you update to OpenSSH 8.8. Note that this feature cannot be used with ssh-keygen from OpenSSH 8.7, whose support for it is broken. In addition to GnuPG, ssh public crypto can be used for object and push-cert signing. This has historically been done through GPG keys, but git 2.34.0 added shipped with a feature that allows users to sign commits with SSH keys as an alternative.

This process allows commit authors to cryptographically sign their commits such that commits may be verified as originating from their author. One potential solution is through commit signature verification.
