title: Setting Key Usage attributes with Makecert
body: <p>Is it possible to set Key Usage attributes using makecert, or any other tool I can use to generate my own test certificates?</p>
  
  <p>The reason I'm interested is that certificates used for BizTalk Server AS2 transport require a key usage of Digital Signature for signing and Data Encipherment or Key Encipherment for encryption/decryption, and I want to play around with this feature.</p>
  
  <p>I see how to set <em>enhanced</em> key usage attributes with makecert, but not key usage.</p>
