You might want to look at RFC 1847: 'Security Multiparts for MIME:
Multipart/Signed and Multipart/Encrypted'. It may solve our problem
with authentication and security.
The brief summary is that there are two new subtypes of multipart:
signed and encrypted. An example from this rfc of a signed document is:
Content-Type: multipart/signed; protocol="TYPE/STYPE";
micalg="MICALG"; boundary="Signed Boundary"
Content-Type: text/plain; charset="us-ascii"
This is some text to be signed although it could be
any type of data, labeled accordingly, of course.
CONTROL INFORMATION for protocol "TYPE/STYPE" would be here
The signature part is always the second of two parts.
