SHA1 collider

Quick-and-dirty PDF maker using the collision from the SHAttered paper.

Choose two image files (must be JPG, roughly the same aspect ratio). For now, each file must be less than 64kB.

Aspect ratio x

(this one is actually even simpler -- just a single comment with the entire first file in it, hence the 64k limit)
