*
* -------------------------------------------------------------------------- **
*
* Notes:
*
* None of this will make any sense unless you're studying RFC 1321 as you
* read the code.
*
* MD5 is described in RFC 1321.
* The MD*4* algorithm is described in RFC 1320 (that's 1321 - 1).
* MD5 is very similar to MD4, but not quite similar enough to justify
* putting the two into a single module. Besides, I wanted to add a few
* extra functions to this one to expand its usability.
*
* There are three primary motivations for this particular implementation.
* 1) Programmer's pride. I wanted to be able to say I'd done it, and I
* wanted to learn from the experience.
* 2) Portability. I wanted an implementation that I knew to be portable
* to a reasonable number of platforms. In particular, the algorithm is
* designed with little-endian platforms in mind, but I wanted an
* endian-agnostic implementation.
* 3) Compactness. While not an overriding goal, I thought it worth-while
* to see if I could reduce the overall size of the result. This is in
* keeping with my hopes that this library will be suitable for use in
* some embedded environments.
* Beyond that, cleanliness and clarity are always worth pursuing.
*
* As mentioned above, the code really only makes sense if you are familiar
* with the MD5 algorithm or are using RFC 1321 as a guide. This code is
* quirky, however, so you'll want to be reading carefully.
*
* Yeah...most of the comments are cut-and-paste from my MD4 implementation.

* Static Constants:
*
* K[][] - In round one, the values of k (which are used to index
* particular four-byte sequences in the input) are simply
* sequential. In later rounds, however, they are a bit more
* varied. Rather than calculate the values of k (which may
* or may not be possible--I haven't though about it) the
* values are stored in this array.
*
* S[][] - In each round there is a left rotate operation performed as
* part of the 16 permutations. The number of bits varies in
* a repeating patter. This array keeps track of the patterns
* used in each round.
*
* T[][] - There are four rounds of 16 permutations for a total of 64.
* In each of these 64 permutation operations, a different
* constant value is added to the mix. The constants are
* based on the sine function...read RFC 1321 for more detail.
* In any case, the correct constants are stored in the T[][]
* array. They're divided up into four groups of 16.

static void Permute(uint32_t ABCD[4], const unsigned char block[64])
/* ------------------------------------------------------------------------ **
* Permute the ABCD "registers" using the 64-byte <block> as a driver.
*
* Input: ABCD - Pointer to an array of four unsigned longwords.
* block - An array of bytes, 64 bytes in size.
*
* Output: none.
*
* Notes: The MD5 algorithm operates on a set of four longwords stored
* (conceptually) in four "registers". It is easy to imagine a
* simple MD4/5 chip that would operate this way. In any case,
* the mangling of the contents of those registers is driven by
* the input message. The message is chopped and finally padded
* into 64-byte chunks and each chunk is used to manipulate the
* contents of the registers.
*
* The MD5 Algorithm calls for padding the input to ensure that
* it is a multiple of 64 bytes in length. The last 16 bytes
* of the padding space are used to store the message length
* (the length of the original message, before padding, expressed
* in terms of bits). If there is not enough room for 16 bytes
* worth of bitcount (eg., if the original message was 122 bytes
* long) then the block is padded to the end with zeros and
* passed to this function. Then *another* block is filled with
* zeros except for the last 16 bytes which contain the length.
*
* Oh... and the algorithm requires that there be at least one
* padding byte. The first padding byte has a value of 0x80,
* and any others are 0x00.

* -------------------------------------------------------------------------- **
*
* Notes:
*
* None of this will make any sense unless you're studying RFC 1321 as you
* read the code.
*
* MD5 is described in RFC 1321.
* The MD*4* algorithm is described in RFC 1320 (that's 1321 - 1).
* MD5 is very similar to MD4, but not quite similar enough to justify
* putting the two into a single module. Besides, I wanted to add a few
* extra functions to this one to expand its usability.
*
* There are three primary motivations for this particular implementation.
* 1) Programmer's pride. I wanted to be able to say I'd done it, and I
* wanted to learn from the experience.
* 2) Portability. I wanted an implementation that I knew to be portable
* to a reasonable number of platforms. In particular, the algorithm is
* designed with little-endian platforms in mind, but I wanted an
* endian-agnostic implementation.
* 3) Compactness. While not an overriding goal, I thought it worth-while
* to see if I could reduce the overall size of the result. This is in
* keeping with my hopes that this library will be suitable for use in
* some embedded environments.
* Beyond that, cleanliness and clarity are always worth pursuing.
*
* As mentioned above, the code really only makes sense if you are familiar
* with the MD5 algorithm or are using RFC 1321 as a guide. This code is
* quirky, however, so you'll want to be reading carefully.
*
* Yeah...most of the comments are cut-and-paste from my MD4 implementation.
