 # SSH Signing Github Support
 
+Github has supported SSH Signing since [August 2022](https://github.blog/changelog/2022-08-23-ssh-commit-verification-now-supported/)
+That being said SSH Commit signing was part of [Git](https://git-scm.com/) [beforehand](https://lore.kernel.org/git/[email protected]/)
+
+If commits were signed before the release on Github, they will still appear as verified provided the SSH public key was still uploaded as a [Signing Key](https://docs.github.com/en/authentication/managing-commit-signature-verification/telling-git-about-your-signing-key#telling-git-about-your-ssh-key)
