Zig Requires Chilkat v11.0.0+

Export Public Key from USB Token or Smartcard using the Apple Keychain

See more Apple Keychain Examples

Demonstrates how to export a public key from a USB token or smart card via the Apple Keychain. Zig

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

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

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

    const cert = try chilkat.Cert.init();
    defer cert.deinit();

    // On MacOS and iOS, the LoadByCommonName function will search the Apple Keychain for the matching certificate.

    // A digital certificate's Common Name (CN) is a field in the certificate that specifies the name of the entity the
    // certificate is issued to. It is often used to identify the domain name, hostname, or organization the certificate represents.

    // For example:
    // - In an SSL/TLS certificate for a website, the CN typically contains the domain name (e.g., "www.example.com").
    // - For certificates representing individuals or organizations, the CN might include the person's name or the organization's name.

    // The CN is part of the certificate's Subject field and is crucial for verifying that the certificate corresponds
    // to the intended entity, especially in SSL/TLS communications.
