public class SMIMESigned extends CMSSignedData
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(MimeMultipart message)
base constructor using a defaultContentTransferEncoding of 7bit
| |
SMIMESigned(MimeMultipart message, String defaultContentTransferEncoding)
base constructor with settable contentTransferEncoding
| |
SMIMESigned(Part message)
base constructor for a signed message with encapsulated content.
|
Method Summary | |
---|---|
MimeBodyPart | getContent()
return the content that was signed. |
MimeMessage | getContentAsMimeMessage(Session session)
Return the content that was signed as a mime message.
|
Object | getContentWithSignature()
return the content that was signed - depending on whether this was
unencapsulated or not it will return a MimeMultipart or a MimeBodyPart |
Throws: MessagingException on an error extracting the signature or otherwise processing the message. CMSException if some other problem occurs.
Parameters: message the signed message defaultContentTransferEncoding new default to use
Throws: MessagingException on an error extracting the signature or otherwise processing the message. CMSException if some other problem occurs.
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. CMSException if some other problem occurs.
Parameters: session
Returns: a MimeMessage holding the content.
Throws: MessagingException
