RIPEMD160 ? - Well, wanna create digest messages that are secure for
the next estimated thousand years ? Okay. Then choose this fine Crypto-
graphic Hash Function program to generate a checksum using the RIPEMD160
algorithm. You get a 20 byte result (instead of 16byte result of MD5).

This program is public domain, but its source-code is not included to
avoid problems with the USA-Law. But interests should contact the author
via eMail :-) to receive the source-code for free. Or consult one of the
internet-search-engines and search for ripemd160.

 After using this program, you can add the results to a document to have
a public checksum against modified software etc. Everybody could check
the validity of the files through RIPEMD160 and the given checksums in
the document.

Overview of the Algorithm
-------------------------
 RIPEMD160 is a MD4 variant and operates on 32bit words. Following ope-
rations are used :
  * bitwise boolean operations (AND, NOT, OR, XOR)
  * two's complement addition of words, denoted by "+". this is modulo
    2^32 addition
  * left rotation (or "left spin") of words.
