Your boss told you that this team has come up with the cryptographic hash of the future, but something about their operation just seems a little fishy.
Here's the site:
So this tells us what we have to do, crack that hash, and make $1000000000000000!
Since they hinted at their hash being twice the strength of md5, I thought I'd just put it into crackstation's hash cracker, and see whats going on.
This shows us that there are 4 byte words in these hashes!
Lets take the MD5 hash of like, and see how it compares to these strings.
md5(like) = be1ab1632e4285edc3733b142935c60b
The hash it was found in is
be1ab1632e4285edc3733b142935c60b90383bad42309f7f6850d2b4250a713d0b2d7a97350465a02554d29d92bfefaf
So the md5 of like is the first 32 chars of the line it was in! Each line of the hash is looking like it is the concatenation of 3 md5's of 4 byte strings!
So I split the given hash into 32 char chunks, and than began brute forcing 4 byte strings with lowercase and UPPERCASE letters, {_}, and numbers.
This gives us:
