git ≥ 2.34: SSH Key Commit Signing Fully Supported

git ≥ 2.34 + SSH commit signing

SSH commit signing was introduced in git 2.34.0 (November 2021). Configure with: `git config --global gpg.format ssh` and `git config --global user.signingkey ~/.ssh/id_ed25519.pub`. Verify signatures with an `allowed_signers` file. GitHub and GitLab both display SSH-signed commit verification badges.

Required Flags / Config

--gpg-sign (-S) on commit/tag commands

Workarounds & Fixes

Automate signing: `git config --global commit.gpgsign true`
Generate SSH key: `ssh-keygen -t ed25519 -C "you@example.com"`
