- mikeash 14y agoFrom the link at the bottom of that page to a collision finder program: > It takes about half an hour on average on a standard PC to find a collision. That's not a whole lot of time. Edit: it really does work, too: $ md5 msg[12].txt MD5 (msg1.txt) = bd1ba334fdd5bf3836b9b8c4bfebae16 MD5 (msg2.txt) = bd1ba334fdd5bf3836b9b8c4bfebae16 $ openssl sha1 msg[12].txt SHA1(msg1.txt)= fd5bb8044dc51ab2deef608fabf3b7dcb7a84c17 SHA1(msg2.txt)= 7d490719b22f9a0e365e4fab4e3ab551b4a8898e Took about half an hour on my MacBook Air, just as promised.
