Difference between AWS Access Key IDs and Secret Access Keys


Hi, I am trying to create a script that picks up Secret Access Keys and want to filter out the Access Key IDs. So far I've noticed Secret Access Keys seem to be longer (usually character length of 40) than Access Key IDs (usually character length of 20). Is this 100% accurate? And are there any other differences I can use?

Thank you.

I recommend you check public projects that already solved this, for example https://github.com/awslabs/git-secrets/blob/master/git-secrets In particular you will realize that they use the following regex to capture the access keys and secret keys

  1. Access Key: (A3T[A-Z0-9]|AKIA|AGPA|AIDA|AROA|AIPA|ANPA|ANVA|ASIA)[A-Z0-9]{16}
  2. Secret Key: [A-Za-z0-9/\+=]{40}

Hope this helps!
