public class SMIMESigned
extends org.bouncycastle.cms.CMSSignedData

general class for handling a pkcs7-signature message.

A simple example of usage - note, in the example below the validity of the certificate isn't verified, just the fact that one of the certs matches the given signer...

  CertStore               certs = s.getCertificates("Collection", "BC");
  SignerInformationStore  signers = s.getSignerInfos();
  Collection              c = signers.getSigners();
  Iterator                it = c.iterator();
  
  while (it.hasNext())
  {
      SignerInformation   signer = (SignerInformation)it.next();
      Collection          certCollection = certs.getCertificates(signer.getSID());
  
      Iterator        certIt = certCollection.iterator();
      X509Certificate cert = (X509Certificate)certIt.next();
  
      if (signer.verify(cert.getPublicKey()))
      {
          verified++;
      }   
  }
 

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".

Constructor Summary

Constructors

Constructor and Description
SMIMESigned(MimeMultipart message) base constructor using a defaultContentTransferEncoding of 7bit
SMIMESigned(MimeMultipart message, java.lang.String defaultContentTransferEncoding) base constructor with settable contentTransferEncoding
SMIMESigned(Part message) base constructor for a signed message with encapsulated content.

Method Summary

Modifier and Type	Method and Description
MimeBodyPart	getContent() return the content that was signed.
MimeMessage	getContentAsMimeMessage(Session session) Return the content that was signed as a mime message.
java.lang.Object	getContentWithSignature() return the content that was signed - depending on whether this was unencapsulated or not it will return a MimeMultipart or a MimeBodyPart

Constructor Detail

SMIMESigned

public SMIMESigned(MimeMultipart message)
            throws MessagingException,
                   org.bouncycastle.cms.CMSException

base constructor using a defaultContentTransferEncoding of 7bit

Throws:

MessagingException - on an error extracting the signature or otherwise processing the message.

org.bouncycastle.cms.CMSException - if some other problem occurs.

SMIMESigned

public SMIMESigned(MimeMultipart message,
                   java.lang.String defaultContentTransferEncoding)
            throws MessagingException,
                   org.bouncycastle.cms.CMSException

base constructor with settable contentTransferEncoding

Parameters:

message - the signed message

defaultContentTransferEncoding - new default to use

Throws:

MessagingException - on an error extracting the signature or otherwise processing the message.

org.bouncycastle.cms.CMSException - if some other problem occurs.

SMIMESigned

public SMIMESigned(Part message)
            throws MessagingException,
                   org.bouncycastle.cms.CMSException,
                   SMIMEException

base constructor for a signed message with encapsulated content.

Throws:

MessagingException - on an error extracting the signature or otherwise processing the message.

SMIMEException - if the body part encapsulated in the message cannot be extracted.

org.bouncycastle.cms.CMSException - if some other problem occurs.

Method Detail

getContent

public MimeBodyPart getContent()

return the content that was signed.

getContentAsMimeMessage

public MimeMessage getContentAsMimeMessage(Session session)
