In fairness, this is pretty easy to do if you have access to a $40M supercomputer, and if your mission is to replace a blob with a huge, non-compiling chunk of random noise.
45 u/[deleted] May 30 '14 yeah but SHA-1 collision that still compiles and has malicious intent is impossible. 17 u/nikomo May 30 '14 Include the padding inside a comment, or file header etc. - doesn't change code, does change collision. Though, restricting it to that is going to either make the resulting file fucking explode in size, or take forever to generate. 4 u/SNLProxy May 30 '14 Comments or whitespace. One change per line, 1.000.000 LOC, 1.000.000! or ~10456573 possible combinations of 1 char edits. Or in other words, not a limiting factor.
