Require SSL Server Certificate Domain Match

See more HTTP Examples

Demonstrates how to require that the SSL server certificate's domain matches the intended domain. Zig

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

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

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    const http = try chilkat.Http.init();
    defer http.deinit();

    // Call SetSslCertRequirement to require that the SSL server certificate's domain
    // matches only the domain we are intending to communicate with.

    // In this example we will test with the URL https://wrong.host.badssl.com/
    // which intentionally has an SSL certificate that does not match "wrong.host.badssl.com"

    http.setSslCertRequirement("SAN", "wrong.host.badssl.com");

    // Also validate the server cert..
    http.setRequireSslCertVerify(true);

    // Try sending the request.  It should fail within the SSL/TLS handshake
    // because the server's certificate does not match the domain "wrong.host.badssl.com"
    _ = http.quickGetStr(alloc, "https://wrong.host.badssl.com/") catch "";
    if (!http.getLastMethodSuccess()) {
        std.debug.print("{s}\n", .{try http.getLastErrorText(alloc)});
    } else {
        std.debug.print("Unexpected success.\n", .{});
    }
