SMIME_WRITE_PKCS7(3)	     OpenSSL	     SMIME_WRITE_PKCS7(3)

NAME
     SMIME_write_PKCS7 - convert PKCS#7 structure to S/MIME for-
     mat.

SYNOPSIS
     int SMIME_write_PKCS7(BIO *out, PKCS7 *p7, BIO *data, int
     flags);

DESCRIPTION
     SMIME_write_PKCS7() adds the appropriate MIME headers to a
     PKCS#7 structure to produce an S/MIME message.

     out is the BIO to write the data to. p7 is the appropriate
     PKCS7 structure. If cleartext signing (multipart/signed) is
     being used then the signed data must be supplied in the data
     argument. flags is an optional set of flags.

NOTES
     The following flags can be passed in the flags parameter.

     If PKCS7_DETACHED is set then cleartext signing will be
     used, this option only makes sense for signedData where
     PKCS7_DETACHED is also set when PKCS7_sign() is also called.

     If the PKCS7_TEXT flag is set MIME headers for type
     text/plain are added to the content, this only makes sense
     if PKCS7_DETACHED is also set.

     If cleartext signing is being used then the data must be
     read twice: once to compute the signature in PKCS7_sign()
     and once to output the S/MIME message.

BUGS
     SMIME_write_PKCS7() always base64 encodes PKCS#7 structures,
     there should be an option to disable this.

     There should really be a way to produce cleartext signing
     using only a single pass of the data.

RETURN VALUES
     SMIME_write_PKCS7() returns 1 for success or 0 for failure.
