Example: Crypt2.ClearEncryptCerts method

Demonstrates how to call the ClearEncryptCerts method. C#

bool success = false;

Chilkat.Crypt2 crypt = new Chilkat.Crypt2();

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

Chilkat.Cert cert1 = new Chilkat.Cert();
//  ...
//  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);

Chilkat.Cert cert2 = new Chilkat.Cert();
//  ...
crypt.AddEncryptCert(cert2);

Chilkat.Cert cert3 = new Chilkat.Cert();
//  ...
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;

Chilkat.BinData bd = new Chilkat.BinData();
//  ...
success = crypt.EncryptBd(bd);

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

Chilkat.Cert cert4 = new Chilkat.Cert();
//  ...
crypt.AddEncryptCert(cert4);

Chilkat.Cert cert5 = new Chilkat.Cert();
//  ...
crypt.AddEncryptCert(cert5);

//  ...
//  ...

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