Add a PFX Source to MailMan from BinData

See more POP3 Examples

Demonstrates the Chilkat MailMan.AddPfxSourceBd method, which adds a PFX/PKCS#12 certificate store to the MailMan object's internal list of sources used for locating certificates and private keys. The first argument is a BinData containing the PFX bytes and the second is the PFX password. This example loads a PFX into a BinData, registers it, and fetches a message Chilkat can decrypt.

  // Load the PFX bytes into a BinData (they could come from a file, database, or secrets store).
  final bdPfx = CkBinData();
  try {
    bdPfx.loadFile('qa_data/certs/decryption.pfx');
  } on ChilkatException catch (e) {

  // Add the PFX as a source of certificates and private keys.
  try {
    mailman.addPfxSourceBd(bdPfx, 'pfx_password');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Fetch a message; if it is encrypted, Chilkat can decrypt it using the PFX source.
  final email = CkEmail();
  try {
    mailman.fetchOne(false, 0, 1, email);
  } on ChilkatException catch (e) {

    return;
  }

  print('Decrypted = ${email.decrypted}');

  // Note: The path "qa_data/certs/decryption.pfx" is a relative local filesystem path,
  // relative to the current working directory of the running application.

  // Note: Explicitly connecting/authenticating is optional.  Chilkat MailMan automatically
  // connects and authenticates -- using the property settings above -- whenever a server
  // operation requires it.  Calling the explicit connect/authenticate methods can still be
  // helpful to determine whether a failure occurs while connecting or while authenticating.
