Client - Mutual SSL

Ballerina supports mutual SSL, which is a certificate-based authentication process in which two parties (the client and server) authenticate each other by verifying the digital certificates. It ensures that both parties are assured of each other’s identity.

For more information on the underlying module, see the HTTP module.

An HTTP client can be configured to initiate new connections that are secured via mutual SSL. The http:ClientSecureSocket record provides the SSL-related configurations.
