      Modifier and Type Method Description
      static org.bouncycastle.asn1.cms.IssuerAndSerialNumber createIssuerAndSerialNumberFor​(java.security.cert.X509Certificate cert)
      Return a CMS IssuerAndSerialNumber structure for the passed in X.509 certificate.
      static java.lang.Object createSafe​(java.io.InputStream sigStream, SMIMEUtil.SafeCreator creator)
      If getInputStreamNoMultipartSigned returns PipedInputStream it will lead to resource leak as it will not be closed if not handled safely.
      static boolean isMultipartContent​(javax.mail.Part part)  
      static javax.mail.internet.MimeBodyPart toMimeBodyPart​(byte[] content)
      return the MimeBodyPart described in the raw bytes provided in content
      static javax.mail.internet.MimeBodyPart toMimeBodyPart​(java.io.InputStream content)
      return the MimeBodyPart described in the input stream content
      static FileBackedMimeBodyPart toMimeBodyPart​(org.bouncycastle.cms.CMSTypedStream content)
      return a file backed MimeBodyPart described in CMSTypedStream content.
      static FileBackedMimeBodyPart toMimeBodyPart​(org.bouncycastle.cms.CMSTypedStream content, java.io.File file)
      Return a file based MimeBodyPart represented by content and backed by the file represented by file.

                                          org.bouncycastle.cms.CMSException
        If getInputStreamNoMultipartSigned returns PipedInputStream it will lead to resource leak as it will not be closed if not handled safely. This method will initiate SMIMESigned but if it fails, it will close PipedInputStream
        Throws:
        javax.mail.MessagingException - an error extracting the signature or otherwise processing the message.
        org.bouncycastle.cms.CMSException - if some other problem occurs.
