I am working with OpenAS2Server-1.3.3 library. There sending a single document is working fine..
Now I wanted to modify it to send document with attachments, like we do with emails. In this scenario, all the decription work well, but signature verification failed (MIC is not matched)
This is how I am tring to send attachments with main doc:
Create a MimeMultipart
and add two MimeBodyPart
into it. (main document and the attachment)
Finally wrap the MimeMultipart
within a MimeBodyPart
(I am not sure this is the way to do this, but anyway Bouncycastle do not have API to sign MimeMultipart
)
Could anyone tell me the correct way to sign a message with attachment ?
MimeBodyPart mainBody = new MimeBodyPart();
mainBody.setDataHandler(new DataHandler(byteSource));
MimeBodyPart attachemt1 = new MimeBodyPart();
attachemt1.attachFile("/home/user/Desktop/Test1.txt");
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(mainBody);
multipart.addBodyPart(attachemt1);
MimeBodyPart body = new MimeBodyPart();
body.setContent(multipart);
body.setHeader("Content-Type", multipart.getContentType());
logger.info("--------------Attaching the file... Done");
