So I just saw this picture on Imgur: http://imgur.com/gxRCrCM
The intriguing thing about it is that the picture refers to an old Daft Punk song named "Face 2 Face". The image's MD5 is
6b0cc07a5c4d3d8fface2face79d8205 which, amazingly enough, contains the phrase
face2face in it.
How does one go about generating this type of hash? I always thought that one gets a totally different hash when even one byte of the message is modified.
What kind of computing power is required to perform this trick? Of course, I am assuming this is not a mere coincidence.
Also I'd love to know if there are other examples of such hashes, and what are some tools available for Linux or Windows?
