	USERGUIDE TODO ChangeLog 
Log Message:
Replaced secure PRNG based on SHA-1 with 128 bits AES in counter
mode. Should be 256 bits, but seems to be a bug in AES key
expansion.

 Implementation note: 
-There is a semantic difference between calling hash on a
-hash object with no data and calling hash on an empty byte vector. Calling
-hash on an empty object is more likely to be a user error and hence returns
-nil. Calling hash on an empty byte vector on the other hand, may simply mean
-that we got very short input and hence returns the initial state of the SHA-1
-algorithm (which is a valid 160 bits byte vector).

 The object oriented interface introduced above is built on top of low level
 function primitives for each algorithm. Sometimes it's easier to work directly

 TODO list for Crypticl
 ======================
 
--Get high entropy seed for PRNG on Windows
+-bug in AES key	expansion for 256-bit keys, maybe others. More test
+cases needed.
+-Get high entropy seed for PRNG on Windows (native API CryptGenRandom,
+Advapi32.dll, Wincrypt.h,)
 -Replace use of SHA-1 in PRNG with a block cipher (AES) in counter mode.
 -Study the Fortuna PRNG.
 -more example applications to test and improve the api
 -SHA-512?
--Document how to run the full test set.
-
+-Document how to run the full test set (when porting to new platform).
+-only use hex and hexo, not the long versions.
