[ aws . iot ]



Gets information about the specified certificate.

Requires permission to access the DescribeCertificate action.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--certificate-id <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--certificate-id (string)

The ID of the certificate. (The last part of the certificate ARN contains the certificate ID.)

--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 use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To get information about a certificate

The following describe-certificate example displays the details for the specified certificate.

aws iot describe-certificate \

certificateMode -> (string)

The mode of the certificate.

DEFAULT : A certificate in DEFAULT mode is either generated by Amazon Web Services IoT Core or registered with an issuer certificate authority (CA) in DEFAULT mode. Devices with certificates in DEFAULT mode aren't required to send the Server Name Indication (SNI) extension when connecting to Amazon Web Services IoT Core. However, to use features such as custom domains and VPC endpoints, we recommend that you use the SNI extension when connecting to Amazon Web Services IoT Core.

SNI_ONLY : A certificate in SNI_ONLY mode is registered without an issuer CA. Devices with certificates in SNI_ONLY mode must send the SNI extension when connecting to Amazon Web Services IoT Core.

For more information about the value for SNI extension, see Transport security in IoT .
