Signature Preservation and Removal

1. Signature preservation is now supported by default in mbox to pst conversion. Added a new MboxToPstConversionOptions.RemoveSignature property, to indicate whether the signature should be removed during conversion. You can set this property to true to remove the signature.

   Public API changes:

   • Added MboxToPstConversionOptions.RemoveSignature property.

   Example usage:

   MboxToPstConversionOptions mboxConversionOptions = new MboxToPstConversionOptions();
   mboxConversionOptions.setRemoveSignature(true);
   PersonalStorage personalStorage = PersonalStorage.create("sample.pst", FileFormatVersion.Unicode);
   MailStorageConverter.mboxToPst(new MboxrdStorageReader("sample.mbox", new MboxLoadOptions()),
       personalStorage, "Inbox", mboxConversionOptions);
   

2. Signature preservation is now supported by default when loading EML files. Added a new LoadOptions.RemoveSignature property, to indicate whether the signature should be removed during loading. You can set this property to true to remove the signature.

   Public API changes:

   • Added LoadOptions.RemoveSignature property.

   Example usage:

   EmlLoadOptions emlLoadOptions = new EmlLoadOptions();
   emlLoadOptions.setRemoveSignature(true);
   MapiMessage msg = MapiMessage.load(fileName, emlLoadOptions);
   

API Enhancement: Secure Email Signature Checking

• Added a new SecureEmailManager class for checking the signature of secure emails. You can now check the signature of MapiMessage and MailMessage objects.
• Added a new SmimeResult class to store the results of checking secure emails.

Public API changes:

• Added SecureEmailManager.checkSignature(MapiMessage msg) method.
• Added SecureEmailManager.checkSignature(MapiMessage msg, X509Certificate2 certificateForDecrypt) method.
• Added SecureEmailManager.checkSignature(MapiMessage msg, X509Certificate2 certificateForDecrypt, X509Store store) method.
• Added SecureEmailManager.checkSignature(MailMessage msg) method.
• Added SecureEmailManager.checkSignature(MailMessage msg, X509Certificate2 certificateForDecrypt) method.
• Added SecureEmailManager.checkSignature(MailMessage msg, X509Certificate2 certificateForDecrypt, X509Store store) method.

Example usage:

MailMessage eml = MailMessage.load(fileName);
SmimeResult result = new SecureEmailManager().checkSignature(eml);

MapiMessage msg = MapiMessage.load(fileName, new EmlLoadOptions());
SmimeResult result = new SecureEmailManager().checkSignature(msg);

String certFileName = "cert.pfx";
X509Certificate2 cert = new X509Certificate2(certFileName, "pass");
MailMessage eml = MailMessage.load(fileName);
X509Store store = new X509Store();
store.open(1);
store.add(cert);
store.close();

SmimeResult result = new SecureEmailManager().checkSignature(eml, cert, store);
