How to decrypt AWS Windows password without using AWS SDK?

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
