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 AWS RSA public certificate.
To validate the instance identity document using the base64-encoded signature and the AWS RSA public certificate
-
Connect to the instance.
-
Retrieve the base64-encoded signature from the instance metadata, convert it to binary, and add it to a file named
signature. Use one of the following commands depending on the IMDS version used by the instance.- IMDSv2
$TOKEN=`curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600"` \ && curl -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/dynamic/instance-identity/signature | base64 -d >>signature- IMDSv1
$curl -s http://169.254.169.254/latest/dynamic/instance-identity/signature | base64 -d >>signature
-
Retrieve the plaintext instance identity document from the instance metadata and add it to a file named
document. Use one of the following commands depending on the IMDS version used by the instance.- IMDSv2
$TOKEN=`curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600"` \ && curl -H "X-aws-ec2-metadata-token: $TOKEN" -v http://169.254.169.254/latest/dynamic/instance-identity/document >>document- IMDSv1
$curl -s http://169.254.169.254/latest/dynamic/instance-identity/document >>document
-
Add the AWS RSA public certificate to a new file named
certificate. Use one of the following commands, depending on the Region of your instance.- Other AWS Regions
-
The following AWS public certificate is for all AWS Regions, except Hong Kong, Bahrain, UAE, Cape Town, Milan, Spain, Zurich, Jakarta, Melbourne, Hyderabad, China, and GovCloud.

Verification successfulmessage appears.The command also writes the contents of the instance identity document to a new file named
document. You can compare the contents of the of the instance identity document from the instance metadata with the contents of this file using the following commands.$openssl dgst -sha256 <document$curl -s -H "X-aws-ec2-metadata-token: $TOKEN" http://169.254.169.254/latest/dynamic/instance-identity/document | openssl dgst -sha256If the signature cannot be verified, contact AWS Support.
