To ensure the security of Classic Load Balancer (CLB) data transfers, when configuring an HTTPS listener, you must either purchase and use a certificate provided by Certificate Management Service or upload a required third-party server certificate and digital identification issued by a certificate authority (CA) to CLB.
CLB supports the following certificates:
Certificates provided by Alibaba Cloud Certificate Management Service: You can configure certificate expiration notifications for these certificates and renew these certificates with a few clicks. Client CA certificates are not supported.
Third-party certificates: To use a third-party certificate, you must upload the certificate files that contain the public key and private key of the certificate. Both HTTPS server certificates and client CA certificates are supported.
Usage notes for adding certificates:
To use a certificate for mutiple regions, select all the desired regions for the Region parameter.
You can add a maximum of 100 server certificates and 100 client CA certificates for each region.
