[Zope] Digital signature and Plone/Zope

[Chris McDonough]

Oops, I suppose that wasn't a very helpful response.  I'll note that  
we used OpenSSL on the server side to verify the signature created by  
CAPICOM via:

openssl smime -verify -inform PEM -CAfile /path/to/ca_cert -content  
<signaturedata>

There was a bunch of buggery on the client side to get the  
<signaturedata> into a format that it could be read.  *This* is the  
code that I won't even look at again without getting paid to do it. ;-)
