|
||||||
|
*
|
||||||
|
* 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.

|
||||||
|
*
|
||||||
|
* 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.

|
||||||

|
||||||
|
* 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

|
||||||
|
*
|
||||||
|
* 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.

* 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.
|
||||||
|
*

* Description:
|
||||||
|
* This file implements the Secure Hashing Standard as defined
|
||||||
|
* in FIPS PUB 180-1 published April 17, 1995.
|
||||||
|
*
|
||||||
|
* The Secure Hashing Standard, which uses the Secure Hashing
|
||||||
|
* Algorithm (SHA), produces a 160-bit message digest for a
|
||||||
|
* given data stream. In theory, it is highly improbable that
|
||||||
|
* two messages will produce the same message digest. Therefore,
|
||||||
|
* this algorithm can serve as a means of providing a "fingerprint"
|
||||||
|
* for a message.
|
||||||
|
*
|
||||||
|
* Portability Issues:
|
||||||
|
* SHA-1 is defined in terms of 32-bit "words". This code was
|
||||||
|
* written with the expectation that the processor has at least
|
||||||
|
* a 32-bit machine word size. If the machine word size is larger,
|
||||||
|
* the code should still function properly. One caveat to that
|
||||||
|
* is that the input functions taking u8acters and u8acter
|
||||||
|
* arrays assume that only 8 bits of information are stored in each
|
||||||
|
* u8acter.
|
||||||
|
*
|
||||||
|
* Caveats:
|
||||||
|
* SHA-1 is designed to work with messages less than 2^64 bits
|
||||||
|
* long. Although SHA-1 allows a message digest to be generated for
|
||||||
|
* messages of any number of bits less than 2^64, this
|
||||||
|
* implementation only works with messages with a length that is a
|
||||||
|
* multiple of the size of an 8-bit u8acter.

||||||
