+MD5 offers basic cryptographic facilities for Lua: a hash (digest)
+function, a pair crypt/decrypt based on MD5 and CFB, and a pair
+crypt/decrypt based on DES with 56-bit keys.

+# 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.
