## org.bouncycastle.mail.smime
Class SMIMESignedGenerator

    java.lang.Object
      org.bouncycastle.mail.smime.SMIMEGenerator
          org.bouncycastle.mail.smime.SMIMESignedGenerator

    public class SMIMESignedGenerator

extends SMIMEGenerator

general class for generating a pkcs7-signature message.

A simple example of usage.

          CertStore           certs...
          SMIMESignedGenerator  fact = new SMIMESignedGenerator();

          fact.addSigner(privKey, cert, SMIMESignedGenerator.DIGEST_SHA1);
          fact.addCertificatesAndCRLs(certs);

          MimeMultipart       smime = fact.generate(content, "BC");

Note: if you are using this class with AS2 or some other protocol that does not use "7bit" as the default content transfer encoding you will need to use the constructor that allows you to specify the default content transfer encoding, such as "binary".
