Upload and share an SSL certificate

Upload a certificate

If you use a certificate that is issued from a third-party service provider, you can upload the certificate to the Certificate Management Service console for centralized management. The certificate can use an internationally accepted algorithm or the SM2 algorithm.

1. Log on to the Certificate Management Service console.

2. In the left-side navigation pane, choose Manage Certificates > SSL Certificate Management.

3. On the Manage Uploaded Certificates tab, click Manage Uploaded Certificates.

4. In the Manage Uploaded Certificates panel, configure the parameters and click OK.

   The parameters that you must configure when you set Certificate Algorithm to Internationally Accepted Algorithm are different from the parameters that you must configure when you set Certificate Algorithm to SM2 Algorithm. The following tables describe the parameters.

   • Internationally Accepted Algorithm

     Parameter	Description

     Parameter	Description
     Certificate Algorithm	Select Internationally Accepted Algorithm. Internationally accepted algorithms refer to encryption algorithms that are extensively reviewed, tested, and approved by international organizations such as the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC). The algorithms include Rivest-Shamir-Adleman (RSA) and elliptic curve cryptography (ECC).
     Certificate Name	Enter a name for the certificate that you want to upload. The name can contain letters, digits, periods (.), underscores (_), and hyphens (-).
     Certificate File	Enter the content of the PEM-encoded certificate file. Required content of the certificate file: If you need to only ensure that the server certificate is trusted, the certificate file must contain the server certificate (marked 1 in the following figure) and the intermediate certificate (marked 2 in the following figure). If your intermediate certificate and server certificate are separate files, you can enter the content of the intermediate certificate in the Certificate Chain field. If you need to ensure that the client certificate and the server certificate are trusted, the certificate file must contain the server certificate (marked 1 in the following figure), intermediate certificate (marked 2 in the following figure), and root certificate (marked 3 in the following figure). If your intermediate certificate, root certificate, and server certificate are separate files, you must concatenate the intermediate certificate and the root certificate in the order shown in the following figure. Then, enter the content of the concatenated file in the Certificate Chain field. Methods to enter the content: Use a text editor to open the certificate file in the PEM or CRT format. Then, copy the content to the Certificate File field. Click Upload below the Certificate File field. Then, select the certificate file from your computer to upload the content of the file.
     Certificate Key	Enter the content of the PEM-encoded private key file. Required content of the private key file: RSA ECC Methods to enter the content: Manually specify the content: Use a text editor to open the private key file in the KEY format. Then, copy the content to the Certificate Key field. Upload the private key file: Click Upload below the Certificate Key field. Then, select the private key file from your computer to upload the content of the file to the field. Select an existing CSR: You can select a certificate signing request (CSR) that is created in or uploaded to the Certificate Management Service console. The system automatically matches the CSR of the specified certificate file. For more information about how to manage CSRs, see Manage CSRs. Note If the system reports an error indicating that the certificate and private key do not match after you upload the private key file, the private key file may contain RSA characters. You can run the openssl rsa -in <Original name of the private key file> -out <New custom name of the private key file> command to convert the characters and re-upload the file.
     Certificate Chain	Optional. Enter the content of the PEM-encoded intermediate certificate or root certificate. If the certificate file that you specify contains the complete certificate chain, you do not need to configure this parameter. Required content of the certificate chain file: Intermediate certificate or root certificate Intermediate certificate (marked 1 in the following figure) and root certificate (marked 2 in the following figure) Methods to enter the content: Use a text editor to open the certificate chain file in the PEM or CRT format. Then, copy the content to the Certificate Chain field. Click Upload below the Certificate Chain field. Then, select the certificate chain file from your computer to upload the content of the file.

   • SM2 Algorithm

     Parameter	Description

     Parameter	Description
     Certificate Algorithm	Select SM2 Algorithm. This type of algorithm is released by the State Cryptography Administration (SCA) of China. Certificate Management Service supports the SM2 algorithm, which is an asymmetric cryptography algorithm.
     Certificate Name	Enter a name for the certificate that you want to upload. The name can contain letters, digits, underscores (_), and hyphens (-).
     Certificate File	Enter the content of the PEM-encoded certificate file of the signing certificate that you want to upload. You can use one of the following methods to enter the content. Method 1: Use a text editor to open the certificate file in the PEM or CRT format. Then, copy the content to the Certificate File field. Method 2: Click Upload below the Certificate File field. Then, select the certificate file from your computer to upload the content of the file.
     Certificate Key	Enter the content of the PEM-encoded private key file of the signing certificate that you want to upload. You can use one of the following methods to enter the content. Method 1: Use a text editor to open the private key file in the KEY format. Then, copy the content to the Certificate Key field. Method 2: Click Upload below the Certificate Key field. Then, select the private key file from your computer to upload the content of the file.
     Encryption Certificate	Enter the content of the PEM-encoded certificate file of the encryption certificate that you want to upload. You can use one of the following methods to enter the content. Method 1: Use a text editor to open the certificate file in the PEM or CRT format. Then, copy the content to the Certificate File field. Method 2: Click Upload below the Certificate File field. Then, select the certificate file from your computer to upload the content of the file.
     Encryption Private Key	Enter the content of the PEM-encoded private key file of the encryption certificate that you want to upload. You can use one of the following methods to enter the content. Method 1: Use a text editor to open the private key file in the KEY format. Then, copy the content to the Encryption Private Key field. Method 2: Click Upload below the Encryption Private Key field. Then, select the private key file from your computer to upload the content of the file.

   After the certificate is uploaded, you can view the certificate in the certificate list. If you do not want to manage an uploaded certificate in the Certificate Management Service console, you can find the certificate and click Delete in the Actions column to delete the certificate.

   Important

   After a certificate is deleted, the certificate is removed from the list of uploaded certificates. The validity period of the certificate is not affected. A deleted certificate cannot be restored. Proceed with caution.

Share a certificate

If you have multiple Alibaba Cloud accounts and the accounts belong to the same individual or enterprise that passed real-name verification, you can share a certificate across the accounts. Then, you can deploy the shared certificate to Alibaba Cloud services free of charge.

Limits

You cannot share a certificate in the following scenarios:

• You cannot share a certificate that is applied for by using an Alibaba Cloud account on the China site (aliyun.com) with an Alibaba Cloud account on the international site (alibabacloud.com). You cannot share a certificate that is applied for by using an Alibaba Cloud account on the international site (alibabacloud.com) with an Alibaba Cloud account on the China site (aliyun.com).

• You cannot share a certificate that is shared to the current Alibaba Cloud account with another Alibaba Cloud account. For example, you have Alibaba Cloud accounts A, B, and C. After you use Account A to share a certificate with Account B, you cannot use Account B to share the certificate with Account C.

• You cannot share an uploaded certificate.

Procedure

1. Log on to the Certificate Management Service console.

2. In the left-side navigation pane, choose Manage Certificates > SSL Certificate Management.

3. On the Official Certificate tab, find the issued certificate that you want to share and click More in the Actions column.

4. On the Share Certificate tab, set the Account ID parameter to the ID of the Alibaba Cloud account with which you want to share the certificate. Then, click Confirm and Share.

   After a certificate is shared, you can log on to the Certificate Management Service console by using the Alibaba Cloud account with which the certificate is shared and go to the Manage Uploaded Certificates tab of the SSL Certificate Management page to view the certificate. The icon is displayed in the Status column of the shared certificate.
