I sent a messages to Verisign, asking why their security program wouldn't work with a basic order form created in Microsoft Front Page 2000. Received this response:

Dear VeriSign Customer,

The problem stems from the fact the extensions embedded within FrontPage do NOT
recognize our new signing hash algorithm of SHA-1. (The hard coded extensions did
recognize the old signing algorithm of MD5...this has been confirmed with Microsoft

For further support, please refer to Microsoft.

Is there any way to make this work?
