How do I validate my Amazon passkey and secret?

Question

I wrote a function to test AWS keys by simply creating an ec2 connection object

import boto.ec2 try: ec2Conn = boto.ec2.connect_to_region(region, aws_access_key_id=access_key, aws_secret_access_key=secret_key) return ec2Conn except boto.exception.EC2ResponseError as e: print e 

But even if the secret key is wrong, it creates an ec2 connection object.

So, I check the access key and the secret key, extracting the areas,

 region = ec2Conn.get_all_regions() 

Is there any method or method, and not a selection area, for checking the access key and secret key?

The only way to verify AWS credentials is to actually use them to sign the request and see if it works. You are right that just creating a connection object does not say anything because it does not fulfill the request. Therefore, you need to select some kind of request that should always work, will not return a huge amount of data and does not create any resources on the server side. I think get_all_regions() is a pretty good choice.
