+      A password-hashing function created by by Alex Biryukov, Daniel Dinu, and
+      Dmitry Khovratovich. Argon2 was declared the winner of the Password
+      Hashing Competition (PHC). There were 24 submissions and 9 finalists.
+      Catena, Lyra2, Makwa and yescrypt were given special recognition. The PHC
+      recommends using Argon2 rather than legacy algorithms.
