예제 1: 이 예제는 Amazon이 지정된 Windows 인스턴스의 관리자 계정에 EC2 할당한 암호를 해독합니다. pem 파일이 지정되면 -Decrypt 스위치의 설정이 자동으로 가정됩니다.

Get-EC2PasswordData -InstanceId i-12345678 -PemFile C:\path\my-key-pair.pem

출력:

mYZ(PA9?C)Q

예제 2: (Windows PowerShell 만 해당) 인스턴스를 검사하여 인스턴스를 시작하는 데 사용되는 키 페어의 이름을 확인한 다음 AWS Toolkit for Visual Studio의 구성 스토어에서 해당 키 페어 데이터를 찾으려고 시도합니다. 키 페어 데이터가 발견되면 암호가 복호화됩니다.

Get-EC2PasswordData -InstanceId i-12345678 -Decrypt

출력:

mYZ(PA9?C)Q

예제 3: 인스턴스에 대해 암호화된 암호 데이터를 반환합니다.

Get-EC2PasswordData -InstanceId i-12345678

출력:
