BrowserUK,

I had to download your code to figure out what you were doing, but now I know your interest in uniqueness was different than mine(i.e. project).

Each of the test encrypted files was unique and we wanted an algorithm that would produce the lowest number of duplicate hashes for the different unique files. The statistics I showed was the number of duplicate hashes produced from unique files. Each hash was generated and then: 

  ...
  $Dupes{$hash}++;
  ...

Then we just counted the total number of keys with values greater than one.

Your code was very interesting and quite a mind tester.

Thank you
