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.
