HMAC is implemnetd on a higher level using a special feature of the

* RIPEMD-160 is not patented, see (as of 25.10.97)

* http://www.esat.kuleuven.ac.be/~bosselae/ripemd160.html

* Note that the code uses Little Endian byteorder, which is good for

|
||||
* Pseudo-code for RIPEMD-160
|
||||
*
|
||||
* RIPEMD-160 is an iterative hash function that operates on 32-bit words.
|
||||
* The round function takes as input a 5-word chaining variable and a 16-word
|
||||
* message block and maps this to a new chaining variable. All operations are
|
||||
* defined on 32-bit words. Padding is identical to that of MD4.
