Example: Crypt2.ClearEncryptCerts method

var success = false;

var crypt = new CkCrypt2();

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

var cert1 = new CkCert();
// ...
// 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);

var cert2 = new CkCert();
// ...
crypt.AddEncryptCert(cert2);

var cert3 = new CkCert();
// ...
crypt.AddEncryptCert(cert3);

// Params for public-key encryption to create PKCS7 enveloped-data
crypt.CryptAlgorithm = "pki";
crypt.Pkcs7CryptAlg = "aes";
crypt.KeyLength = 256;
crypt.OaepHash = "sha256";
crypt.OaepPadding = true;

var bd = new CkBinData();
// ...
success = crypt.EncryptBd(bd);

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

var cert4 = new CkCert();
// ...
crypt.AddEncryptCert(cert4);

var cert5 = new CkCert();
// ...
crypt.AddEncryptCert(cert5);

// ...
// ...

// Encrypt using cert4 and cert5.
success = crypt.EncryptBd(bd);
