# `GetPasswordData`与 AWS SDK 或 CLI 配合使用
以下代码示例演示如何使用 `GetPasswordData`。
------
#### [ CLI ]
**AWS CLI**
**获取加密密码**
此示例将获取加密密码。
命令:
```
aws ec2 get-password-data --instance-id i-1234567890abcdef0
```
输出：
```
{
"InstanceId": "i-1234567890abcdef0",
"Timestamp": "2013-08-07T22:18:38.000Z",
"PasswordData": "gSlJFq+VpcZXqy+iktxMF6NyxQ4qCrT4+gaOuNOenX1MmgXPTj7XEXAMPLE

}
```
**获取解密密码**
此示例将获取解密密码。
命令:
```
aws ec2 get-password-data --instance-id i-1234567890abcdef0 --priv-launch-key C:\Keys\MyKeyPair.pem
```
输出：
```
{
"InstanceId": "i-1234567890abcdef0",
"Timestamp": "2013-08-30T23:18:05.000Z",
"PasswordData": "&ViJ652e*u"
}
```

#### [ PowerShell ]
**适用于 PowerShell V4 的工具**
**示例 1：此示例解密 Amazon EC2 分配给指定 Windows 实例的管理员账户的密码。当指定了 pem 文件时，将自动假定 -Decrypt 开关的设置。**
```
Get-EC2PasswordData -InstanceId i-12345678 -PemFile C:\path\my-key-pair.pem
```
**输出**：
```
mYZ(PA9?C)Q
```
**示例 2：（ PowerShell 仅限 Windows）检查实例以确定用于启动实例的密钥对的名称，然后尝试在 Visual Studio T AWS oolkit for Visual Studio 的配置存储中查找相应的密钥对数据。如果找到了密钥对数据，则对密码进行解密。**
```
Get-EC2PasswordData -InstanceId i-12345678 -Decrypt
```
**输出**：
```
mYZ(PA9?C)Q
```
**示例 3：返回实例的已加密密码数据。**
```
Get-EC2PasswordData -InstanceId i-12345678
```
**输出**：
```
iVz3BAK/WAXV.....dqt8WeMA==
```
+ 有关 API 的详细信息，请参阅 *AWS Tools for PowerShell Cmdlet 参考 (V* 4) [GetPasswordData](https://docs.aws.amazon.com/powershell/v4/reference)中的。
**适用于 PowerShell V5 的工具**
**示例 1：此示例解密 Amazon EC2 分配给指定 Windows 实例的管理员账户的密码。当指定了 pem 文件时，将自动假定 -Decrypt 开关的设置。**
```
Get-EC2PasswordData -InstanceId i-12345678 -PemFile C:\path\my-key-pair.pem
```
**输出**：
```
mYZ(PA9?C)Q
```
**示例 2：（ PowerShell 仅限 Windows）检查实例以确定用于启动实例的密钥对的名称，然后尝试在 Visual Studio T AWS oolkit for Visual Studio 的配置存储中查找相应的密钥对数据。如果找到了密钥对数据，则对密码进行解密。**
```
Get-EC2PasswordData -InstanceId i-12345678 -Decrypt
```
**输出**：
```
mYZ(PA9?C)Q
```
**示例 3：返回实例的已加密密码数据。**
```
Get-EC2PasswordData -InstanceId i-12345678
