||||
* 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.
