+ * This is a major rewrite of my old public domain DES code written
+ * circa 1987, which in turn borrowed heavily from Jim Gillogly's 1977
+ * public domain code. I pretty much kept my key scheduling code, but
+ * the actual encrypt/decrypt routines are taken from from Richard
+ * Outerbridge's DES code as printed in Schneier's "Applied Cryptography."
+ *
+ * This code is in the public domain. I would appreciate bug reports and
+ * enhancements.
