+ * This is an original implementation of the DES and the crypt(3) interfaces
+ * by David Burren <davidb@werj.com.au>.
+ *
+ * An excellent reference on the underlying algorithm (and related
+ * algorithms) is:
+ *
+ *	B. Schneier, Applied Cryptography: protocols, algorithms,
+ *	and source code in C, John Wiley & Sons, 1994.
+ *
+ * Note that in that book's description of DES the lookups for the initial,
+ * pbox, and final permutations are inverted (this has been brought to the
+ * attention of the author).  A list of errata for this book has been
+ * posted to the sci.crypt newsgroup by the author and is available for FTP.
+ *
+ * ARCHITECTURE ASSUMPTIONS:
+ *	It is assumed that the 8-byte arrays passed by reference can be
+ *	addressed as arrays of u_int32_t's (ie. the CPU is not picky about
+ *	alignment).
