|
|
.SH "NAME"
|
|
SMIME_read_PKCS7 \- parse S/MIME message.
|
|
.SH "SYNOPSIS"
|
|
.IX Header "SYNOPSIS"
|
|
\&\s-1PKCS7\s0 *SMIME_read_PKCS7(\s-1BIO\s0 *in, \s-1BIO\s0 **bcont);
|
|
.SH "DESCRIPTION"
|
|
.IX Header "DESCRIPTION"
|
|
\&\fISMIME_read_PKCS7()\fR parses a message in S/MIME format.
|
|
.PP
|
|
\&\fBin\fR is a \s-1BIO\s0 to read the message from.
|
|
.PP
|
|
If cleartext signing is used then the content is saved in
|
|
a memory bio which is written to \fB*bcont\fR, otherwise
|
|
\&\fB*bcont\fR is set to \fB\s-1NULL\s0\fR.
|
|
.PP
|
|
The parsed PKCS#7 structure is returned or \fB\s-1NULL\s0\fR if an
|
|
error occurred.
|
|
.SH "NOTES"
|
|
.IX Header "NOTES"
|
|
If \fB*bcont\fR is not \fB\s-1NULL\s0\fR then the message is clear text
|
|
signed. \fB*bcont\fR can then be passed to \fIPKCS7_verify()\fR with
|
|
the \fB\s-1PKCS7_DETACHED\s0\fR flag set.
|
|
.PP
|
|
Otherwise the type of the returned structure can be determined
|
|
using \fIPKCS7_type()\fR.
|
|
.PP
|
|
To support future functionality if \fBbcont\fR is not \fB\s-1NULL\s0\fR
|
|
\&\fB*bcont\fR should be initialized to \fB\s-1NULL\s0\fR. For example:
|
|
.PP
|
|
.Vb 2
|
|
\& BIO *cont = NULL;
|
|
\& PKCS7 *p7;
|
|
.Ve
|
|
.PP
|
|
.Vb 1
|
|
\& p7 = SMIME_read_PKCS7(in, &cont);
|
|
.Ve
|
|
.SH "BUGS"
|
|
.IX Header "BUGS"
|
|
The \s-1MIME\s0 parser used by \fISMIME_read_PKCS7()\fR is somewhat primitive.
|
|
While it will handle most S/MIME messages more complex compound
|
|
formats may not work.
|
|
.PP
|
|
The parser assumes that the \s-1PKCS7\s0 structure is always base64
|
|
encoded and will not handle the case where it is in binary format
|
|
or uses quoted printable format.
|
|
.PP
|
|
The use of a memory \s-1BIO\s0 to hold the signed content limits the size
|
|
of message which can be processed due to memory restraints: a
|
|
streaming single pass option should be available.
|
|
.SH "RETURN VALUES"
|
|
.IX Header "RETURN VALUES"
|
|
\&\fISMIME_read_PKCS7()\fR returns a valid \fB\s-1PKCS7\s0\fR structure or \fB\s-1NULL\s0\fR
|
|
is an error occurred. The error can be obtained from \fIERR_get_error\fR\|(3).
|
|
.SH "SEE ALSO"
|
