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

SMIMESigned(javax.mail.internet.MimeMultipart message)
base constructor using a defaultContentTransferEncoding of 7bit

SMIMESigned(javax.mail.internet.MimeMultipart message, java.lang.String defaultContentTransferEncoding)
base constructor with settable contentTransferEncoding

SMIMESigned(javax.mail.Part message)
base constructor for a signed message with encapsulated content.

Method Summary

javax.mail.internet.MimeBodyPart	getContent() return the content that was signed.
javax.mail.internet.MimeMessage	getContentAsMimeMessage(javax.mail.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
