Password hashing for Unix founders

In published in publicly available dumps of historical snapshots with BSD 3 code, there is also a file /etc/passwd with the hashed passwords of the founders of Unix. Since the passwords are hashed using the DES method, which poses no problem for modern computing power, enthusiasts attempted to recover the passwords used by the founders of Unix.

Almost all passwords of the Unix founders were cracked almost immediately. For example, Brian Kernighan's password was an easily typeable combination of "/.,/.,,"; Dennis Ritchie's password was "dmac"; Kirk McKusick's was "foobar"; and Steven Bourne's was "bourne."

The exception was Ken Thompson's password. In 2014, after several days of computation, the password remained uncracked. Just a few days ago another attempt was made, and after more than 4 days of cracking using hashcat on a system with an AMD Radeon Vega64 graphics card, the password was finally determined (the cracking performance reached 930 million hashes per second). The password turned out to be "p/q2-q4!" Chess enthusiasts noted that this is the beginning of a series of chess openings .
