+.Sh DESCRIPTION
+.Fn SMIME_write_ASN1
+generates an S/MIME message on
+.Fa out_bio
+by writing MIME 1.0 headers
+followed by a BER- and base64-encoded serialization of
+.Fa val_in ,
+which can be of the type
+.Vt CMS_ContentInfo
+or
+.Vt PKCS7
+and has to match the
+.Fa it
+argument.
+.Pp
+The
+.Fa flags
+can be the logical OR of zero or more of the following bits:
+.Bl -tag -width Ds
+.It Dv PKCS7_REUSE_DIGEST
+Skip the calls to
+.Xr PKCS7_dataInit 3
+and
+.Xr PKCS7_dataFinal 3 .
+This flag has no effect unless
+.Dv SMIME_DETACHED
+is also set.
+It is normally used if
+.Fa out_bio
+is already set up to calculate and finalize the digest when written through.
+.It Dv SMIME_BINARY
+If specified, this flag is passed through to
+.Xr SMIME_crlf_copy 3 .
+.It Dv SMIME_CRLFEOL
+End MIME header lines with pairs of carriage return and newline characters.
+By default, no carriage return characters are written
+and header lines are ended with newline characters only.
+.It Dv SMIME_DETACHED
+Use cleartext signing.
+Generate a
+.Qq multipart/signed
+S/MIME message using the
+.Fa micalg
+argument and ignoring the
+.Fa ctype_nid
+and
+.Fa econt_nid
+arguments.
+The content is read from
+.Fa in_bio .
+If
+.Fa in_bio
+is a
+.Dv NULL
+pointer, this flag is ignored.
+.Pp
+If this flag is ignored or not specified,
+the smime-type is chosen according to
+.Fa ctype_nid
+instead:
+.Bl -tag -width Ds
+.It Dv NID_pkcs7_enveloped
+.Qq enveloped-data
+.It Dv NID_pkcs7_signed
+.Qq signed-receipt
+if
+.Fa econt_nid
+is
+.Dv NID_id_smime_ct_receipt
+.br
+.Qq signed-data
+if
+.Fa micalg
+is not empty
+.br
+.Qq certs-only
+if
+.Fa micalg
+is empty
+.It Dv NID_id_smime_ct_compressedData
+.Qq compressed-data
+.El
+.It Dv SMIME_OLDMIME
+In Content-Type headers, use
+.Qq application/x-pkcs7-mime
+or
+.Qq application/x-pkcs7-signature .
+By default,
+.Qq application/pkcs7-mime
+or
+.Qq application/pkcs7-signature
+are used instead.
+.It Dv SMIME_STREAM
+Perform streaming by passing this flag through to
+.Xr i2d_ASN1_bio_stream 3
+and reading the content from
+.Fa in_bio .
+This only works if
+.Dv SMIME_DETACHED
+is not specified.
+.It SMIME_TEXT
+Prepend the line
+.Qq Content-Type: text/plain
+to the content.
+This only makes sense if
+.Dv SMIME_DETACHED
+is also set.
+It is ignored if the flag
+.Dv SMIME_BINARY
+is also set.
+.El
+.Sh RETURN VALUES
+.Fn SMIME_write_ASN1
+is intended to return 1 on success or 0 on failure.

+.Sh BUGS
+.Fn SMIME_write_ASN1
+ignores most errors and is likely to return 1
+even after producing corrupt or incomplete output.
