SMIMECompressedGenerator

public class SMIMECompressedGenerator extends SMIMEGenerator
General class for generating a pkcs7-mime compressed message. A simple example of usage. 
SMIMECompressedGenerator fact = new SMIMECompressedGenerator();

MimeBodyPart smime = fact.generate(content, algorithm);
Note: Most clients expect the MimeBodyPart to be in a MimeMultipart when it's sent.
