金鑰概覽
| 金鑰類型 | RSA 4096 |
|---|---|
| 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:r87pfWBR4SuuEEn1C+YC0c+mntL4rZT3QGXF/+mD6jg |
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。

test_1MB.bin 的簽章
在 CH-J Tools 中以此金鑰產生的 test_1MB.bin 分離式 SSH 簽章（SSHSIG，命名空間為 "file"）。請將其儲存為 test_1MB.bin.sig，與測試檔案放在同一個目錄。

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
