如何在不使用AWS SDK的情况下解密AWS Windows密码？

Question

I deployed a windows machine on AWS with a key pair. I want the windows administrator password.

I got the windows encrypted password using:

var myEC2GetPasswordDataResult = ec2Client2.getPasswordData(myEC2GetPasswordDataRequest);

myEC2GetPasswordDataResult = myEC2GetPasswordDataResult.withInstanceId("instanceID");
System.log( myEC2GetPasswordDataResult.toString());

myEC2GetPasswordDataResult.getPasswordData()

Now how can I decrypt this password?

I tried many options with castlebouncy but none of them worked.

If you don't want to use AWS SDK , another way to decrypt the password is to use OpenSSL.

Here is the example using command-line:

printf 'BASE64ENCODEDSTRING==' | openssl rsautl -decrypt -inkey mykey.pem
