public class SMIMESignedGenerator

extends SMIMEGenerator

general class for generating a pkcs7-signature message.

A simple example of usage. X509Certificate signCert = [] KeyPair signKP = [] List certList = new ArrayList(); certList.add(signCert); Store certs = new JcaCertStore(certList); SMIMESignedGenerator gen = new SMIMESignedGenerator(); gen.addSignerInfoGenerator(new JcaSimpleSignerInfoGeneratorBuilder().setProvider("BC").build("SHA1withRSA", signKP.getPrivate(), signCert)); gen.addCertificates(certs); MimeMultipart smime = fact.generate(content);

Note 1: 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".

Note 2: between RFC 3851 and RFC 5751 the values used in the micalg parameter for signed messages changed. We will accept both, but the default is now to use RFC 5751. In the event you are dealing with an older style system you will also need to use a constructor that sets the micalgs table and call it with RFC3851_MICALGS.
