=head1 NAME

|
|
|
SMIME_write_CMS - convert CMS structure to S/MIME format
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/cms.h>
|
|
|
|
int SMIME_write_CMS(BIO *out, CMS_ContentInfo *cms, BIO *data, int flags);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SMIME_write_CMS() adds the appropriate MIME headers to a CMS
|
|
structure to produce an S/MIME message.
|
|
|
|
B<out> is the BIO to write the data to. B<cms> is the appropriate
|
|
B<CMS_ContentInfo> structure. If streaming is enabled then the content must be
|
|
supplied in the B<data> argument. B<flags> is an optional set of flags.
|
|
|
|
=head1 NOTES
|
|
|
|
The following flags can be passed in the B<flags> parameter.
|
|
|
|
If B<CMS_DETACHED> is set then cleartext signing will be used, this option only
|
|
makes sense for SignedData where B<CMS_DETACHED> is also set when CMS_sign() is
|
|
called.
|
|
|
|
If the B<CMS_TEXT> flag is set MIME headers for type B<text/plain> are added to
|
|
the content, this only makes sense if B<CMS_DETACHED> is also set.
|
|
|
|
If the B<CMS_STREAM> flag is set streaming is performed. This flag should only
|
|
be set if B<CMS_STREAM> was also set in the previous call to a CMS_ContentInfo
|
|
creation function.
|
|
|
|
If cleartext signing is being used and B<CMS_STREAM> not set then the data must
|
|
be read twice: once to compute the signature in CMS_sign() and once to output
|
|
the S/MIME message.
|
|
|
|
If streaming is performed the content is output in BER format using indefinite
|
|
length constructed encoding except in the case of signed data with detached
|
|
content where the content is absent and DER format is used.
|
|
|
|
=head1 BUGS
|
|
|
|
SMIME_write_CMS() always base64 encodes CMS structures, there should be an
|
|
option to disable this.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SMIME_write_CMS() returns 1 for success or 0 for failure.
