Hi!

I've been looking for a way to digitally sign an e-mail with .NET
1.1 and I haven't been able to find any way of doing this except by buying a
third party product or using CDO/OOM/ExtMAPI.
I read somewhere that an e-mail can be signed by attaching a pk* file, is
this true? is it standard? (will e-mail clients recognize this?)

Thanks in advance

I don't know of a way to do this in native .NET 1.x with the crypto classes
included as there is no support for PKCS in .NET 1.x. I only know of
solutions using CDO combined with CAPICOM, crypto API p/invoke or third
party products.

I haven't quite figured out how to make this work in .NET 2.0 yet, even with
the PKCS support as it isn't yet clear to me how to use the various mail and
mime classes to build the correct email message.
