[ aws . iot ]



Registers a device certificate with IoT. If you have more than one CA certificate that has the same subject field, you must specify the CA certificate that was used to sign the device certificate being registered.

Requires permission to access the RegisterCertificate action.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--certificate-pem <value>
[--ca-certificate-pem <value>]
[--set-as-active | --no-set-as-active]
[--status <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--certificate-pem (string)

The certificate data, in PEM format.

--ca-certificate-pem (string)

The CA certificate used to sign the device certificate being registered.

--set-as-active | --no-set-as-active (boolean)

A boolean value that specifies if the certificate is set to active.

--status (string)

The status of the register certificate request.

Possible values:


--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


To register a self signed device certificate

The following register-certificate example registers the deviceCert.pem device certificate signed by the rootCA.pem CA certificate. The CA certificate must be registered before you use it to register a self-signed device certificate. The self-signed certificate must be signed by the same CA certificate you pass to this command.

aws iot register-certificate \
    --certificate-pem file://deviceCert.pem \
    --ca-certificate-pem file://rootCA.pem
