Uploading a Certificate to WAF

If you select Dedicated for Protection and set Client Protocol to HTTPS, a certificate is required for your website.

If you upload a certificate to WAF, you can directly select the certificate when adding a website to WAF.

If you have enabled enterprise projects, ensure that you have all operation permissions for the project where your WAF instance locates. Then, you can select your enterprise project from the Enterprise Project drop-down list and upload certificates in the project.

Prerequisites

You have obtained the certificate file and certificate private key.

Specification Limitations

You can create as many certificates in WAF as the number of domain names that can be protected by your WAF instances in the same account. For example, if WAF can protect 10 domain names, you can create 10 certificates in WAF.

Constraints

If you import a new certificate when adding a protected website or updating a certificate, the certificate is added to the certificate list on the Certificates page, and the imported certificate is also counted towards your total certificate quota.

Application Scenario

If you select HTTPS for Client Protocol, a certificate is required.

Uploading a Certificate to WAF

1. Log in to the management console.
2. Click in the upper left corner of the management console and select a region or project.
3. Click in the upper left corner and choose Web Application Firewall (Dedicated) under Security.

   Figure 1 Upload Certificate
   
   Only .pem certificates can be used in WAF. If the certificate is not in .pem format, convert it into .pem locally by referring to Table 1 before uploading it.

   Table 1 Certificate conversion commands

   Format	Conversion Method
   CER/CRT	Rename the cert.crt certificate file to cert.pem.
   PFX	Obtain a private key. For example, run the following command to convert cert.pfx into key.pem: openssl pkcs12 -in cert.pfx -nocerts -out key.pem -nodes Obtain a certificate. For example, run the following command to convert cert.pfx into cert.pem: openssl pkcs12 -in cert.pfx -nokeys -out cert.pem
   P7B	Convert a certificate. For example, run the following command to convert cert.p7b into cert.cer: openssl pkcs7 -print_certs -in cert.p7b -out cert.cer Rename certificate file cert.cer to cert.pem.
   DER	Obtain a private key. For example, run the following command to convert privatekey.der into privatekey.pem: openssl rsa -inform DER -outform PEM -in privatekey.der -out privatekey.pem Obtain a certificate. For example, run the following command to convert cert.cer into cert.pem: openssl x509 -inform der -in cert.cer -out cert.pem

   

   • Before running an OpenSSL command, ensure that the OpenSSL tool has been installed on the local host.
   • If your local PC runs a Windows operating system, go to the command line interface (CLI) and then run the certificate conversion command.

7. Click Confirm.

Verification

The certificate you created is displayed in the certificate list.
