Question about chosen-prefix collision with strings. #14

Closed andrecoco closed 2 years ago

Hi! Thank you for this project, really nice. But i have a question if is possible to find md5 collisions using two string prefixes in a way that the collisions only have "normal characters" added, because using the script i was able to find a collision, but it had some LF and CR, and some 0 bytes in it.

Theoretically it's possible to have printable-chars only collisions. But these tools don't support this case, unfortunately.

Ok, thank you for the reply!
