Use the base64-encoded signature to verify the instance identity document

This topic explains how to verify the instance identity document using the base64-encoded signature and the Amazon RSA public certificate.

To validate the instance identity document using the base64-encoded signature and the Amazon RSA public certificate
  1. Connect to the instance.

  2. Retrieve the base64-encoded signature from the instance metadata, convert it to a byte array, and add it to variable named $Signature. Use one of the following commands depending on the IMDS version used by the instance.

    IMDSv2
    PS C:\> [string]$token = (Invoke-WebRequest -Method Put -Headers @{'X-aws-ec2-metadata-token-ttl-seconds' = '21600'} http://169.254.169.254/latest/api/token).Content
    PS C:\> $Signature = [Convert]::FromBase64String((Invoke-WebRequest -Headers @{'X-aws-ec2-metadata-token' = $Token} http://169.254.169.254/latest/dynamic/instance-identity/signature).Content)
    IMDSv1
    PS C:\> $Signature = [Convert]::FromBase64String((Invoke-WebRequest http://169.254.169.254/latest/dynamic/instance-identity/signature).Content)
  3. Retrieve the plaintext instance identity document from the instance metadata, convert it to a byte array, and add it to a variable named $Document. Use one of the following commands depending on the IMDS version used by the instance.

    IMDSv2
    PS C:\> $Document = [Text.Encoding]::UTF8.GetBytes((Invoke-WebRequest -Headers @{'X-aws-ec2-metadata-token' = $Token} http://169.254.169.254/latest/dynamic/instance-identity/document).Content)
    IMDSv1
    PS C:\> $Document = [Text.Encoding]::UTF8.GetBytes((Invoke-WebRequest http://169.254.169.254/latest/dynamic/instance-identity/document).Content)
  4. Add one of the following Amazon RSA public certificates to a new file named certificate.pem, depending on the Region of your instance.
