/*-
 * This is a generic 32 bit "collector" for message digest algorithms.
 * Whenever needed it collects input character stream into chunks of
 * 32 bit values and invokes a block function that performs actual hash
 * calculations.
 *
 * Porting guide.
 *
 * Obligatory macros:
 *
 * DATA_ORDER_IS_BIG_ENDIAN or DATA_ORDER_IS_LITTLE_ENDIAN
 *      this macro defines byte order of input stream.
 * HASH_CBLOCK
 *      size of a unit chunk HASH_BLOCK operates on.
 * HASH_LONG
 *      has to be at lest 32 bit wide, if it's wider, then
 *      HASH_LONG_LOG2 *has to* be defined along
 * HASH_CTX
 *      context structure that at least contains following
 *      members:
 *              typedef struct {
 *                      ...
 *                      HASH_LONG       Nl,Nh;
 *                      either {
 *                      HASH_LONG       data[HASH_LBLOCK];
 *                      unsigned char   data[HASH_CBLOCK];
 *                      };
 *                      unsigned int    num;
 *                      ...
 *                      } HASH_CTX;
 *      data[] vector is expected to be zeroed upon first call to
 *      HASH_UPDATE.
 * HASH_UPDATE
 *      name of "Update" function, implemented here.
 * HASH_TRANSFORM
 *      name of "Transform" function, implemented here.
 * HASH_FINAL
 *      name of "Final" function, implemented here.
 * HASH_BLOCK_DATA_ORDER
 *      name of "block" function capable of treating *unaligned* input
 *      message in original (data) byte order, implemented externally.
 * HASH_MAKE_STRING
 *      macro convering context variables to an ASCII hash string.
 *
 * MD5 example:
 *
 *      #define DATA_ORDER_IS_LITTLE_ENDIAN
 *
 *      #define HASH_LONG               MD5_LONG

/*
 * This comment was originaly written for MD5, which is why it
 * discusses A-D. But it basically applies to all 32-bit digests,
 * which is why it was moved to common header file.
 *
 * In case you wonder why A-D are declared as long and not
 * as MD5_LONG. Doing so results in slight performance
 * boost on LP64 architectures. The catch is we don't
 * really care if 32 MSBs of a 64-bit register get polluted
 * with eventual overflows as we *save* only 32 LSBs in
 * *either* case. Now declaring 'em long excuses the compiler
 * from keeping 32 MSBs zeroed resulting in 13% performance
 * improvement under SPARC Solaris7/64 and 5% under AlphaLinux.
 * Well, to be honest it should say that this *prevents*
 * performance degradation.
