For those unaware, PHK created (amongst other things) the MD5crypt password hashing algorithm ($1$…). It came before bcrypt (1999), scrypt (2009), SHA2crypt (2016), etc, and was committed in 1994:

* https://github.com/freebsd/freebsd-src/commit/3b2b7f71deba2a...
To clarify: not MD5 itself. It was created in 1991 by Ron Rivest. (It is my experience that knowledge of these things isn't as widely distributed as one might hope.)
I first came across it in 1995/1996: Wow, what a magical tool for backend web stuff! I used it for everything.
Wait, is that the same guy who co-authorer the Floyd-Rivest Algorithm? Hmm, looks like it[0]. Huh, neat.

Also the same Rivest as Cormen, Leiserson and Rivest (that Stein dude was after my time), and the R in RSA.
Okay.
What qualifications does phk have that are relevant to the current subject?
