Configure a Socket for Server-Side TLS

See more Socket/SSL/TLS Examples

Demonstrates Socket.InitSslServer, which configures the object for server-side TLS using a server certificate that has access to its private key, then listens for and accepts a TLS connection.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const socket = try chilkat.Socket.init();
    defer socket.deinit();

    // The file path is relative to the application's current working directory.  An absolute path
    // may also be used.  Supply the path appropriate to your own environment.
    // The PFX password should come from a secure source rather than being hard-coded.
    const pfx_password = "myPfxPassword";
    const cert = try chilkat.Cert.init();
    defer cert.deinit();
    cert.loadPfxFile("qa_data/server.pfx", pfx_password) catch {
        std.debug.print("{s}\n", .{try cert.getLastErrorText(alloc)});
        return;
    };

    // Configure this object for server-side TLS using the certificate.  The certificate must have
    // access to its corresponding private key.
    socket.initSslServer(cert) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

    // Listen for connections.  Accepted connections will use TLS.
    socket.bindAndListen(5000, 25) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

    const connected_sock = try chilkat.Socket.init();
    defer connected_sock.deinit();
    socket.acceptNext(20000, connected_sock) catch {
        std.debug.print("{s}\n", .{try socket.getLastErrorText(alloc)});
        return;
    };

    std.debug.print("Accepted a TLS client connection.\n", .{});
