=head1 NAME

|
|
|
SMIME_write_PKCS7 - convert PKCS#7 structure to S/MIME format
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/pkcs7.h>
|
|
|
|
int SMIME_write_PKCS7(BIO *out, PKCS7 *p7, BIO *data, int flags);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SMIME_write_PKCS7() adds the appropriate MIME headers to a PKCS#7
|
|
structure to produce an S/MIME message.
|
|
|
|
B<out> is the BIO to write the data to. B<p7> is the appropriate B<PKCS7>
|
|
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<PKCS7_DETACHED> is set then cleartext signing will be used,
|
|
this option only makes sense for signedData where B<PKCS7_DETACHED>
|
|
is also set when PKCS7_sign() is also called.
|
|
|
|
If the B<PKCS7_TEXT> flag is set MIME headers for type B<text/plain>
|
|
are added to the content, this only makes sense if B<PKCS7_DETACHED>
|
|
is also set.
|
|
|
|
If the B<PKCS7_STREAM> flag is set streaming is performed. This flag should
|
|
only be set if B<PKCS7_STREAM> was also set in the previous call to
|
|
PKCS7_sign() or PKCS7_encrypt().
|
|
|
|
If cleartext signing is being used and B<PKCS7_STREAM> not set then
|
|
the data must be read twice: once to compute the signature in PKCS7_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_PKCS7() always base64 encodes PKCS#7 structures, there
|
|
should be an option to disable this.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SMIME_write_PKCS7() returns 1 for success or 0 for failure.
