+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\fBSMIME_read_ASN1_ex()\fR parses a message in S/MIME format.
+.PP
+\&\fIin\fR is a \s-1BIO\s0 to read the message from.
+If the \fIflags\fR argument contains \fB\s-1CMS_BINARY\s0\fR then the input is assumed to be
+in binary format and is not translated to canonical form.
+If in addition \fB\s-1SMIME_ASCIICRLF\s0\fR is set then the binary input is assumed
+to be followed by \fB\s-1CR\s0\fR and \fB\s-1LF\s0\fR characters, else only by an \fB\s-1LF\s0\fR character.
+\&\fIx\fR can be used to optionally supply
+a previously created \fIit\fR \s-1ASN1_VALUE\s0 object (such as CMS_ContentInfo or \s-1PKCS7\s0),
+it can be set to \s-1NULL.\s0 Valid values that can be used by \s-1ASN.1\s0 structure \fIit\fR
+are ASN1_ITEM_rptr(\s-1PKCS7\s0) or ASN1_ITEM_rptr(CMS_ContentInfo). Any algorithm
+fetches that occur during the operation will use the \fB\s-1OSSL_LIB_CTX\s0\fR supplied in
+the \fIlibctx\fR parameter, and use the property query string \fIpropq\fR See
+\&\*(L"\s-1ALGORITHM FETCHING\*(R"\s0 in \fBcrypto\fR\|(7) for further details about algorithm fetching.
+.PP
+If cleartext signing is used then the content is saved in a memory bio which is
+written to \fI*bcont\fR, otherwise \fI*bcont\fR is set to \s-1NULL.\s0
+.PP
+The parsed \s-1ASN1_VALUE\s0 structure is returned or \s-1NULL\s0 if an error occurred.
+.PP
+\&\fBSMIME_read_ASN1()\fR is similar to \fBSMIME_read_ASN1_ex()\fR but sets the value of \fIx\fR
+to \s-1NULL\s0 and the value of \fIflags\fR to 0.
+.SH "NOTES"
+.IX Header "NOTES"
+The higher level functions \fBSMIME_read_CMS_ex\fR\|(3) and
+\&\fBSMIME_read_PKCS7_ex\fR\|(3) should be used instead of \fBSMIME_read_ASN1_ex()\fR.
+.PP
+To support future functionality if \fIbcont\fR is not \s-1NULL\s0 \fI*bcont\fR should be
+initialized to \s-1NULL.\s0
+.SH "BUGS"
+.IX Header "BUGS"
+The \s-1MIME\s0 parser used by \fBSMIME_read_ASN1_ex()\fR is somewhat primitive. While it will
+handle most S/MIME messages more complex compound formats may not work.
+.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"
+\&\fBSMIME_read_ASN1_ex()\fR and \fBSMIME_read_ASN1()\fR return a valid \fB\s-1ASN1_VALUE\s0\fR
+structure or \fB\s-1NULL\s0\fR if an error occurred. The error can be obtained from
+\&\fBERR_get_error\fR\|(3).
