Example: Crypt2.ClearEncryptCerts method

Demonstrates how to call the ClearEncryptCerts method. Zig

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

pub fn main() !void {
    const crypt = try chilkat.Crypt2.init();
    defer crypt.deinit();

    // Tell the crypt object to use 3 certificates.
    // Do this by calling AddEncryptCert for each certificate.

    const cert1 = try chilkat.Cert.init();
    defer cert1.deinit();
    // ...
    // Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc.
    // ...
    crypt.addEncryptCert(cert1);

    const cert2 = try chilkat.Cert.init();
    defer cert2.deinit();
    // ...
    crypt.addEncryptCert(cert2);

    const cert3 = try chilkat.Cert.init();
    defer cert3.deinit();
    // ...
    crypt.addEncryptCert(cert3);

    // Params for public-key encryption to create PKCS7 enveloped-data
    crypt.setCryptAlgorithm("pki");
    crypt.setPkcs7CryptAlg("aes");
    crypt.setKeyLength(256);
    crypt.setOaepHash("sha256");
    crypt.setOaepPadding(true);

    const bd = try chilkat.BinData.init();
    defer bd.deinit();
    // ...
    try crypt.encryptBd(bd);

    // Let's say we now want to encrypt something else with different certs..
    // First clear the encryption certs.
    crypt.clearEncryptCerts();

    const cert4 = try chilkat.Cert.init();
    defer cert4.deinit();
    // ...
    crypt.addEncryptCert(cert4);

    const cert5 = try chilkat.Cert.init();
    defer cert5.deinit();
    // ...
    crypt.addEncryptCert(cert5);

    // ...
    // ...

    // Encrypt using cert4 and cert5.
    try crypt.encryptBd(bd);
