This statement alone suggests you are not the right person to design a new hash function accepted for public use.

I challenge you to change a publicly known file, let's say CentOS-6.3-i386-bin-DVD1.iso...

...and add the string "diep was here" anywhere in the file without changing the MD5 Hash of "0285160d8ba3cfc720ea55e98e464eac" nor the size of the file.

You are allowed to use as many rainbow tables and algorithms as you like in this challenge.
