+在 GitHub 的 commit 历史中看到的 “Verified” 标记，表示该提交是经过 签名验证（signed commit） 的，也就是 GitHub 能确认这个 commit 的确是由声明的提交者（你）签名并发布的。可以通过GPG或者SSH配置：
+
+- GPG方式
+
+```
+sudo pacman -S gnupg //安装 GPG
+gpg --full-generate-key //生成 GPG 密钥
+gpg --list-secret-keys --keyid-format=long //查看你生成的密钥 ID

+git config --global commit.gpgsign true //启用自动签名所有提交
+gpg --armor --export ABCDEF1234567890 //导出公钥并添加到 GitHub
+```
+然后前往``GitHub → Settings → SSH and GPG keys → New GPG key``粘贴并保存。
+
+- SSH方式
+
+可以用你平时登录 GitHub 的同一个 SSH 密钥：
+```
+git config --global gpg.format ssh //让 Git 使用 SSH 格式签名
+git config --global user.signingkey ~/.ssh/Github.pub //指定使用的 SSH 公钥
+git config --global commit.gpgsign true  //表示自动签名所有提交
+```
+然后前往``Settings → SSH and GPG keys → New SSH key → Signing key``粘贴并保存。

+```
+mkdir -p ~/.ssh
+nano ~/.ssh/allowed_signers

+写入你的 ``test@mail.com ssh-ed25519 AAAABBBBBBBBBBBBBBBBxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx``并保存。
+随后配置Git信任该文件：

+git config --global gpg.ssh.allowedSignersFile ~/.ssh/allowed_signers
