範例 04 · RSA 3072

RSA 金鑰：支援最廣泛的 SSH 金鑰類型。簽章使用 rsa-sha2-512；目前的 OpenSSH 已停用使用 SHA-1 的舊式 ssh-rsa 簽章。金鑰越大，速度越慢，但安全餘裕也越大。

金鑰概覽

金鑰類型RSA 3072
SSH 演算法名稱ssh-rsa · signatures rsa-sha2-512
支援情況廣泛支援；目前的 OpenSSH 要求使用 RSA-SHA2 簽章（rsa-sha2-256 或 rsa-sha2-512），因為使用 SHA-1 的 ssh-rsa 簽章自 OpenSSH 8.8 起已預設停用
私密金鑰格式OpenSSH (openssh-key-v1), unencrypted
指紋SHA256:HS3S7ghNmNJ8H0+gMwQBxkihRgCChGVIS8mYRsy0K7g

公開金鑰

authorized_keys 格式的公開金鑰。將其加入 allowed_signers 檔案，即可驗證下方的簽章。

撤銷

SSH 金鑰沒有撤銷憑證。若要撤銷金鑰，請將其從 authorized_keys 移除，或列入 OpenSSH 金鑰撤銷清單（KRL，以 ssh-keygen -k 建立），讓伺服器透過 RevokedKeys 設定讀取該清單。

驗證簽章

將公開金鑰與簽章儲存到 test_1MB.bin 所在的目錄，建立 allowed_signers 檔案，然後執行 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
