I know.. I blush. I've become such a netjunkie that not being able to find
any of the answers on web pages, or Cypherpunk logs I just panicked.

Thank you everyone who sent me a message with the reference.

I'd say more, but I have to run and get my fix in.

(Btw... what would be the absolute coolest thing folk would like to see
added to RSAREF? That is, other than code that we will need to negotiate
for. What new thing, speed upgrade, enhancement, etc would just tickle?)

	Consistant pricing.  The knowledge that any app I develop
using RSAREF can be made into licensed for commercial use product for
a set, known, published fee.  This would be the biggest win for
Consensus.

	Another really big win would be to add more entry points to
the code to legitimize Wei Dai's excellent Crypto++ library, which has
to jump in at all sorts of unpublished interfaces.

How about just making all the interfaces at the different levels 
available.  For the next version of SSLeay (when I get it and the 
documentation finished) will have defined interfaces at the following 
levels for the various ciphers etc.

The actual cipher level
	eg des_set_key, des_cfb_encrypt, idea_cbc_encrypt...
	This level is wanted by things like SSL for the fastest on the fly
	encryption possible.

The 'by parts' routines
	eg EncryptBegin, EncryptUpdate, EncryptFinish (which take a CIPHER 
	pointer as an argument).
	This is sort of wanted by people implementing higher level digital 
	signature routines but they are usefull in their own right.

The 'digital' envelope routines.
	eg SealBegin, SealUpdate, SealFinish (which take a CIPHER pointer, a 	
	MD pointer and the public keys etc.
	The high level stuff for PKCS-7/S-MIME/PEM etc.

I am also documenting the interface to the big number library (anyone 
want to do DSS :-).
