The document, like many other security documents, tells too much 
about what will not work, too little on what will work. It seems as 
if security experts are better at telling you that something is 
dangerous or might not be secure, than telling you how to get 
security. I would prefer to get more practical advice with
recommendations on how to get the security you want.

This may be a reason why security techniques have so much trouble 
getting accepted and used.

I was interested to note the warnings against MD5, since MD5 is so 
popular. But why not tell us what we should use instead of MD5, 
instead of just saying that MD5 has security risks.

There was no mention of the export restriction problem with
encryption tools. Is this not a major problem? How can you
resolve it?
