Description
Interface Summary | |
AddressMismatch | An interface to represent a Warning generated from a mismatch between a sender e-mail address and address(es) in the sender certificate. |
DecryptionResult | An interface to represent the result of decrypting an S/MIME encrypted message. |
VerificationResult | An interface to represent the result of verifying an S/MIME signed message. |
Warning | An interface to represent abnormal (but non-fatal) conditions encountered during S/MIME signed message verification. |
Class Summary | |
SMIMECipher | A class for encryption and decryption of MIME messages according to RFC 2633 "S/MIME Version 3 Message Specification". |
SMIMESignature | A class for signing and verification of MIME messages according to RFC 2633 "S/MIME Version 3 Message Specification". |
SMIMEUtil | A utility class for S/MIME message processing |
Exception Summary | |
SMIMEException | A generic S/MIME exception class |
This package defines classes and interfaces for S/MIME v3 as specified in IETF RFC 2633 "S/MIME Version 3 Message Specification". It relies upon the CMS package com.dstc.security.cms, and on the standard JavaMail API (at least version 1.2). In particular, it assumes knowledge of the latter.
S/MIME (Secure/Multipurpose Internet Mime Extensions) provides cryptographic security services for messaging applications based on the Internet MIME standard. Such services include authentication, message integrity and non-repudiation through digital signatures, and message privacy through encryption. The S/MIME specification defines several MIME content types for signed and/or encrypted messages, relying on IETF RFC 2630 "Cryptographic Message Syntax" (CMS) for cryptographic enhancement of messages.
The main classes in this package are
SMIMESignature
and
SMIMECipher
.
SMIMESignature
is for signing and
verification of MIME messages, whereas
SMIMECipher
is
for encryption and decryption of MIME messages. Appropriately initialized
instances of these classes can operate on MIME messages given as instances
of
MimeMessage
defined in the JavaMail API.
For signing and encryption, new instances of
MimeMessage
are generated as a result.
For verification (respectively, decryption) of an S/MIME message, a
VerificationResult
(respectively, DecryptionResult
)
instance is returned. From this can be obtained the message with CMS
enhancement removed (ie. the original message or "payload") together with
CMS information (through
EnvelopedData
in the case of encrypted messages and
SignedData
in the case of signed messages.
During S/MIME verification, abnormal (but usually, non-critical) conditions
may be encountered, and can be accessed through
VerificationResult
as instances of the
Warning
interface. In the present version,
the only
Warning
supported is
AddressMismatch
,
indicating a mismatch between a sender address and address(es) in the
sender X.509 certificate.
