**To upload a signing certificate for an IAM user**

The following ``upload-signing-certificate`` command uploads a signing certificate for the IAM user named ``Bob``. ::

    aws iam upload-signing-certificate \
        --user-name Bob \
        --certificate-body file://certificate.pem

Output::

    {
        "Certificate": {
            "UserName": "Bob",
            "Status": "Active",
            "CertificateBody": "-----BEGIN CERTIFICATE-----<certificate-body>-----END CERTIFICATE-----",
            "CertificateId": "TA7SMP42TDN5Z26OBPJE7EXAMPLE",
            "UploadDate": "2013-06-06T21:40:08.121Z"
        }
    }
