Re:How I created two images with the same MD5 hash by dnet on Tuesday November 04, 2014 @03:25AM (#8555578)
1. git uses SHA-1, not MD5; former has problems, but is still better than latter

2. git stores the length of a blob before hashing [1] which makes it harder (but not impossible) to perform such attacks [2]
