Renew Certificate

Update a certificate and bind the updated certificate to the specified device.

Operation Permissions

Required Authorization	Required Operation Permission
Device Management	Full Access

Prerequisites

• The device exists and is registered on EnOS.

• The product to which the device belongs to supports bi-directional authentication.

• The certificate to be updated is bound to the device.

• The certificate to be updated is valid.

Request Format

POST https://{apigw-address}/connect-service/v2.0/certificates?action=renew

Request Parameters (URI)

Note

Use one of the following methods to specify the device:

• Include assetId in the request

• Include productKey + deviceKey in the request

Request Parameters (URI)

Name	Location (Path/Query)	Mandatory/Optional	Data Type	Description
orgId	Query	Mandatory	String	The organization ID which the asset belongs to. How to get orgId>>
assetId	Query	Optional (See Note above)	String	The asset ID. How to get assetId>>
productKey	Query	Optional (See Note above)	String	The product key. To be used with deviceKey.
deviceKey	Query	Optional (See Note above)	String	The device key. To be used with productKey.

Request Parameters (Body)

Request Parameters (Body)

Name	Mandatory/Optional	Data Type	Description
csr	Optional	String	The CSR file (Certificate Signing Request) in the Privacy-Enhanced Mail (PEM) format. If this parameter is not included in the request, a certificate will be generated based on the request data of the existing certificate. For details on how to generate a CSR file, see Creating your Certificate Signing Request (CSR) File>>
certSn	Mandatory	Integer	The certificate number to be updated.
validDay	Optional	Integer	The validity period of the certificate in days. If not specified, the default value used would be “730”. The rules that apply to this parameter are listed below.
issueAuthority	Optional	String	The type of certificate to apply for. Only accepts two values: “RSA” (default) and “ECC”. The rules that apply to this parameter are listed below.

Rules for the Validity Period of a Certificate (validDay)

To use validDay in a request, the following rules apply:

• When the user does not specify validDay in the request, the default value, “730”, would be used.

• When the user specifies validDay in the request:

  • If the specified value is no greater than the maximum validity period of the product that this device belongs to, the user-specified value is used.

  • If the specified value is greater than the maximum validity period of the product that this device belongs to, the request will fail and an error message will be returned.

  • If the default or specified value (not greater than the maximum validity period of the product) is greater than the remaining validity period of the certificate authority’s root certificate (root CA), then the remaining validity period of the root CA would be used.

Rules for issueAuthority

• If issueAuthority is not specified in a request, the default value, “RSA”, would be used.

• The two certificate types applicable for issueAuthority are “RSA” and “ECC”. If other values are given, an error would be returned.

• It is not case-sensitive.

Certificate Type Description

• RSA: To apply for an RSA certificate, a Certificate Signing Request (.csr) file is required. The CSR file must use 2048-bit RSA public key. The signature algorithm must be “SHA256withRSA”.

• ECC: To apply for an ECC certificate, a Certificate Signing Request (.csr) file is required. The CSR file must use 256-bit ECC public key. The public key algorithm is “prime256v1”. The signature algorithm must be “SHA256withECDSA”.

Response Parameters

Response Parameters (Body)
