Method Summary

Modifier and Type	Method and 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 javax.mail.internet.MimeBodyPart	toMimeBodyPart(byte[] content) return the MimeBodyPart described in the raw bytes provided in 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.
static javax.mail.internet.MimeBodyPart	toMimeBodyPart(java.io.InputStream content) return the MimeBodyPart described in the input stream content

toMimeBodyPart

public static FileBackedMimeBodyPart toMimeBodyPart(org.bouncycastle.cms.CMSTypedStream content,
                                                    java.io.File file)
                                             throws SMIMEException

Return a file based MimeBodyPart represented by content and backed by the file represented by file.

Parameters:

content - content stream containing body part.

file - file to store the decoded body part in.

Returns:

the decoded body part.

Throws:

SMIMEException

createIssuerAndSerialNumberFor

public static org.bouncycastle.asn1.cms.IssuerAndSerialNumber createIssuerAndSerialNumberFor(java.security.cert.X509Certificate cert)
                                                                                      throws java.security.cert.CertificateParsingException

Return a CMS IssuerAndSerialNumber structure for the passed in X.509 certificate.

Parameters:

cert - the X.509 certificate to get the issuer and serial number for.

Returns:

an IssuerAndSerialNumber structure representing the certificate.

Throws:

java.security.cert.CertificateParsingException

createSafe

public static java.lang.Object createSafe(java.io.InputStream sigStream,
                                          SMIMEUtil.SafeCreator creator)
                                   throws javax.mail.MessagingException,
                                          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.
