public class Md5Crypt extends Object
Based on the public domain ("beer-ware") C implementation from Poul-Henning Kamp which was found at:
crypt-md5.c @ freebsd.org
Source:
$FreeBSD: src/lib/libcrypt/crypt-md5.c,v 1.1 1999/01/21 13:50:09 brandon Exp $
Conversion to Kotlin and from there to Java in 2012.
The C style comments are from the original C code, the ones with "//" from the port.
This class is immutable and thread-safe.

The algorithm is identical to the crypt(3) "$1$" one but produces different outputs due to the different salt prefix.
