**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"
      }
  }
