SSL/TLS certificate
To create a rule using the LeastConn algorithm and HTTPS protocol, in addition to the load balancer and server ports, you must upload the public certificate and private key.
HTTPS (
HyperText Transfer Protocol Secure) is the use of the HTTP protocol over a connection protected by TLS (
Transport Layer Security), ensuring secure and encrypted communication.
The default port used for HTTPS traffic is 443.
An SSL/TLS certificate uses a pair of cryptographic keys:
- a public key (included in the public certificate), associated with the identity of the server;
- a private key, securely stored and used by the server to prove possession of the key associated with the certificate during the connection.
Public certificate
It allows the client to verify the identity of the server through the digital signature issued by a certification authority (CA).

-----END CERTIFICATE-----
Private key
It is used by the server during the TLS connection to prove possession of the key associated with the public certificate and to establish secure communication with the client.
