CRYPTPLUG is an independent cryptography plug-in API

developed for Sphinx-enabeling KMail and Mutt.
|

CRYPTPLUG was designed for the Aegypten project, but it may

be used by 3rd party developers as well to design pluggable

crypto backends for the above mentioned MUAs.

|
|
\brief This class provides C++ access to the StructuringInfo helper
|
|
struct that is specified in cryptplug.h to hold information
|
|
returned by signing and by encrypting functions.
|
|
|
|
Use this information to compose a MIME object containing signed
|
|
and/or encrypted content (or to build a text frame around your
|
|
flat non-MIME message body, resp.)
|
|
|
|
\note This class is different from the respective cryptplug.h class
|
|
because this one takes care for freeing the char** members' memory
|
|
automatically. You must <b>not</b> call the \c free function for
|
|
any of it's members - just ignore the advise given in the
|
|
cryptplug.h documentation!
|
|
|
|
<b>If</b> value returned in \c makeMimeObject is <b>TRUE</b> the
|
|
text strings returned in \c contentTypeMain and \c contentDispMain
|
|
and \c contentTEncMain (and, if required, \c content[..]Version and
|
|
\c bodyTextVersion and \c content[..]Sig) should be used to compose
|
|
a respective MIME object.<br>
|
|
If <b>FALSE</b> the texts returned in \c flatTextPrefix and
|
|
\c flatTextSeparator and \c flatTextPostfix are to be used instead.<br>
|
|
Always <b>either</b> the \c content[..] and \c bodyTextVersion
|
|
parameters <b>or</b> the \c flatText[..] parameters are holding
|
|
valid data - never both of them may be used simultaneously
|
|
as plugins will just ignore the parameters not matching their
|
|
\c makeMimeObject setting.
|
|
|
|
When creating your MIME object please observe these common rules:
|
|
\li Parameters named \c contentType[..] and \c contentDisp[..] and
|
|
\c contentTEnc[..] will return the values for the respective MIME
|
|
headers 'Content-Type' and 'Content-Disposition' and
|
|
'Content-Transfer-Encoding'. The following applies to these parameters:
|
|
\li The relevant MIME part may <b>only</b> be created if the respective
|
|
\c contentType[..] parameter is holding a non-zero-length string. If the
|
|
\c contentType[..] parameter value is invalid or holding an empty string
|
|
the respective \c contentDisp[..] and \c contentTEnc[..] parameters
|
|
should be ignored.
|
|
\li If the respective \c contentDisp[..] or \c contentTEnc[..] parameter
|
|
is NULL or holding a zero-length string it is up to you whether you want
|
|
to add the relevant MIME header yourself, but since it in in the
|
|
responsibility of the plugin implementors to provide you with all
|
|
necessary 'Content-[..]' header information you should <b>not need</b>
|
|
to define them if they are not returned by the signing or encrypting
|
|
function - otherwise this may be considered as a bug in the plugin and
|
|
you could report the missing MIME header information to the address
|
|
returned by the \c bugURL() function.
|
|
|
|
If \c makeMultiMime returns FALSE the \c contentTypeMain returned must
|
|
not be altered but used to specify a single part mime object holding the
|
|
code bloc, e.g. this is used for 'enveloped-data' single part MIME
|
|
objects. In this case you should ignore both the \c content[..]Version
|
|
and \c content[..]Code parameters.
|
|
|
|
If \c makeMultiMime returns TRUE also the following rules apply:
|
|
\li If \c includeCleartext is TRUE you should include the cleartext
|
|
as first part of our multipart MIME object, typically this is TRUE
|
|
when signing mails but FALSE when encrypting.
|
|
\li The \c contentTypeMain returned typically starts with
|
|
"multipart/" while providing a "protocol" and a "micalg" parameter: just
|
|
add an appropriate \c "; boundary=[your \c boundary \c string]" to get
|
|
the complete Content-Type value to be used for the MIME object embedding
|
|
both the signed part and the signature part (or - in case of
|
|
encrypting - the version part and the code part, resp.).
|
|
\li If \c contentTypeVersion is holding a non-zero-length string an
|
|
additional MIME part must added immediately before the code part, this
|
|
version part's MIME headers must have the unaltered values of
|
|
\c contentTypeVersion and (if they are holding non-zero-length strings)
|
|
\c contentDispVersion and \c contentTEncVersion, the unaltered contents
|
|
of \c bodyTextVersion must be it's body.
|
|
\li The value returned in \c contentTypeCode is specifying the complete
|
|
Content-Type to be used for this multipart MIME object's signature part
|
|
(or - in case of encrypting - for the code part following after the
|
|
version part, resp.), you should not add/change/remove anything here
|
|
but just use it's unaltered value for specifying the Content-Type header
|
|
of the respective MIME part.
|
|
\li The same applies to the \c contentDispCode value: just use it's
|
|
unaltered value to specify the Content-Disposition header entry of
|
|
the respective MIME part.
|
|
\li The same applies to the \c contentTEncCode value: just use it's
|
|
unaltered value to specify the Content-Transfer-Encoding header of
|
|
the respective MIME part.
|
|
|
|
<b>If</b> value returned in \c makeMimeObject is <b>FALSE</b> the
|
|
text strings returned in \c flatTextPrefix and \c flatTextPostfix
|
|
should be used to build a frame around the cleartext and the code
|
|
bloc holding the signature (or - in case of encrypting - the encoded
|
|
data bloc, resp.).<br>
|
|
If \c includeCleartext is TRUE this frame should also include the
|
|
cleartext as first bloc, this bloc should be divided from the code bloc
|
|
by the contents of \c flatTextSeparator - typically this is used for
|
|
signing but not when encrypting.<br>
|
|
If \c includeCleartext is FALSE you should ignore both the cleartext
|
|
and the \c flatTextSeparator parameter.
|
|
|
|
<b>How to use StructuringInfoWrapper data in your program:</b>
|
|
\li To compose a signed message please act as described below.
|
|
\li For constructing an encrypted message just tqreplace the
|
|
\c signMessage() call by the respective \c encryptMessage() call
|
|
and then proceed exactly the same way.
|
|
\li In any case make <b>sure</b> to free your \c ciphertext when
|
|
you are done with processing the data returned by the signing
|
|
(or encrypting, resp.) function.
