-This is the reference C implementation of Argon2, the password-hashing
-function that won the Password Hashing Competition (PHC).
-
-Argon2 is a password-hashing function that summarizes the state of the art
-in the design of memory-hard functions and can be used to hash passwords
-for credential storage, key derivation, or other applications.
-
-It has a simple design aimed at the highest memory filling rate and effective
-use of multiple computing units, while still providing defense against
-tradeoff attacks (by exploiting the cache and memory organization of the
-recent processors).

-# HOW TO EDIT THIS FILE:
-# The "handy ruler" below makes it easier to edit a package description.
-# Line up the first '|' above the ':' following the base package name, and
-# the '|' on the right side marks the last column you can put a character in.
-# You must make exactly 11 lines for the formatting to be correct.  It's also
-# customary to leave one space after the ':' except on otherwise blank lines.
