密钥概览
| 密钥类型 | RSA 2048 |
|---|---|
| SSH 算法名称 | ssh-rsa · signatures rsa-sha2-512 |
| 支持情况 | 广泛支持；当前 OpenSSH 要求使用 RSA-SHA2 签名（rsa-sha2-256 或 rsa-sha2-512），因为使用 SHA-1 的 ssh-rsa 签名自 OpenSSH 8.8 起已默认禁用 |
| 私钥格式 | OpenSSH (openssh-key-v1), unencrypted |
| 指纹 | SHA256:PRraUEAOnitXGs/jNcwuT0k+04aW793ywqkTFmFmY5g |
公钥
authorized_keys 格式的公钥。将其添加到 allowed_signers 文件中，即可验证下方的签名。

吊销
SSH 密钥没有吊销证书。要撤销密钥，请将其从 authorized_keys 中移除，或将其列入 OpenSSH 密钥吊销列表（KRL，使用 ssh-keygen -k 创建），让服务器通过 RevokedKeys 配置读取该列表。
验证签名
将公钥和签名保存到 test_1MB.bin 所在的目录中，创建 allowed_signers 文件，然后运行 ssh-keygen：
echo "example@ch-j $(cat id_rsa.pub)" > allowed_signers
ssh-keygen -Y verify -f allowed_signers -I example@ch-j -n file -s test_1MB.bin.sig < test_1MB.bin
