#### [ CLI ]
**AWS CLI**
**匯出私有 CA 發行的私有憑證。**
下列 `export-certificate` 命令會將私有憑證、憑證鏈和私有金鑰匯出到您的顯示器：
```
aws acm export-certificate --certificate-arn arn:aws:acm:region:account:certificate/12345678-1234-1234-1234-123456789012 --passphrase file://path-to-passphrase-file
```
若要將憑證、鏈結和私有金鑰匯出至本機檔案，請使用下列命令：
```
aws acm export-certificate --certificate-arn arn:aws:acm:region:sccount:certificate/12345678-1234-1234-1234-123456789012 --passphrase file://path-to-passphrase-file > c:\temp\export.txt
```
