Is there any built in functionality to MIME a file in C# .Net? What I am looking to do is:
- Convert a file into a MIME message
- Sign the MIME Message to a pcks 7 blob
- MIME that pkcs 7 blob
- Finally encrypt the entire thing.
Any suggestions on how I would go about this (not the encryption or signing part but the MIMEing)? What exactly is envolved in MIMEing a file?
There is a good commercial package for a small fee:
