I was going to start implementing the Cypto API (in advapi32.dll) over the 
next few weeks.  As of yet these functions are no more than stubs.  However, 
I am finding increased use of this API as more applications becomed 
networkable and relying more heavily on internet connections.

I was hoping to implement these functions by using the OpenSSL library 
(if/when available).  This library seems to have similar capabilities.

One of my concerns is about legal issues.  What special concerns should I 
note about cryptographic software?  Are there any special copyright issues I 
should be aware of?

Another question is about design.  M$ seems to split the cryptographic 
software into different dlls (rsabase.dll, rsasig.dll, dssbase.dll, etc.). 
Should I do this as well so that, applications can use the native dlls if 
necessary or should I simply implement it entirely though advapi32.dll which 
and avoid the need to create several new (and very small) dlls under wine?  
Because most of the code is already in another library (OpenSSL) creating 
extra dlls seems abit unnecessary.
