/*
* This file contains some functions which implement the external data
* handling and padding for Merkle-Damgard hash functions which follow
* the conventions set out by MD4 (little-endian) or SHA-1 (big-endian).
*
* API: this file is meant to be included, not compiled as a stand-alone
* file. Some macros must be defined:
* RFUN name for the round function
* HASH "short name" for the hash function
* BE32 defined for big-endian, 32-bit based (e.g. SHA-1)
* LE32 defined for little-endian, 32-bit based (e.g. MD5)
* BE64 defined for big-endian, 64-bit based (e.g. SHA-512)
* LE64 defined for little-endian, 64-bit based (no example yet)
* PW01 if defined, append 0x01 instead of 0x80 (for Tiger)
* BLEN if defined, length of a message block (in bytes)
* PLW1 if defined, length is defined on one 64-bit word only (for Tiger)
* PLW4 if defined, length is defined on four 64-bit words (for WHIRLPOOL)
* SVAL if defined, reference to the context state information
*
* BLEN is used when a message block is not 16 (32-bit or 64-bit) words:
* this is used for instance for Tiger, which works on 64-bit words but
* uses 512-bit message blocks (eight 64-bit words). PLW1 and PLW4 are
* ignored if 32-bit words are used; if 64-bit words are used and PLW1 is
* set, then only one word (64 bits) will be used to encode the input
* message length (in bits), otherwise two words will be used (as in
* SHA-384 and SHA-512). If 64-bit words are used and PLW4 is defined (but
* not PLW1), four 64-bit words will be used to encode the message length
* (in bits). Note that regardless of those settings, only 64-bit message
* lengths are supported (in bits): messages longer than 2 Exabytes will be
* improperly hashed (this is unlikely to happen soon: 2 Exabytes is about
* 2 millions Terabytes, which is huge).
*
* If CLOSE_ONLY is defined, then this file defines only the sph_XXX_close()
* function. This is used for Tiger2, which is identical to Tiger except
* when it comes to the padding (Tiger2 uses the standard 0x80 byte instead
* of the 0x01 from original Tiger).
*
* The RFUN function is invoked with two arguments, the first pointing to
* aligned data (as a "const void *"), the second being state information
* from the context structure. By default, this state information is the
* "val" field from the context, and this field is assumed to be an array
* of words ("sph_u32" or "sph_u64", depending on BE32/LE32/BE64/LE64).
* from the context structure. The "val" field can have any type, except
* for the output encoding which assumes that it is an array of "sph_u32"
* values. By defining NO_OUTPUT, this last step is deactivated; the
* includer code is then responsible for writing out the hash result. When
* NO_OUTPUT is defined, the third parameter to the "close()" function is
* ignored.

/**
* RIPEMD, RIPEMD-128 and RIPEMD-160 interface.
*
* RIPEMD was first described in: Research and Development in Advanced
* Communication Technologies in Europe, "RIPE Integrity Primitives:
* Final Report of RACE Integrity Primitives Evaluation (R1040)", RACE,
* June 1992.
*
* A new, strengthened version, dubbed RIPEMD-160, was published in: H.
* Dobbertin, A. Bosselaers, and B. Preneel, "RIPEMD-160, a strengthened
* version of RIPEMD", Fast Software Encryption - FSE'96, LNCS 1039,
* Springer (1996), pp. 71--82.
*
* This article describes both RIPEMD-160, with a 160-bit output, and a
* reduced version called RIPEMD-128, which has a 128-bit output. RIPEMD-128
* was meant as a "drop-in" replacement for any hash function with 128-bit
* output, especially the original RIPEMD.
*
* @warning Collisions, and an efficient method to build other collisions,
* have been published for the original RIPEMD, which is thus considered as
* cryptographically broken. It is also very rarely encountered, and there
* seems to exist no free description or implementation of RIPEMD (except
* the sphlib code, of course). As of january 2007, RIPEMD-128 and RIPEMD-160
* seem as secure as their output length allows.

/*
* This macro defines the body for a SHA-384 / SHA-512 compression function
* implementation. The "in" parameter should evaluate, when applied to a
* numerical input parameter from 0 to 15, to an expression which yields
* the corresponding input block. The "r" parameter should evaluate to
* an array or pointer expression designating the array of 8 words which
* contains the input and output of the compression function.
*
* SHA-512 is hard for the compiler. If the loop is completely unrolled,
* then the code will be quite huge (possibly more than 100 kB), and the
* performance will be degraded due to cache misses on the code. We
* unroll only eight steps, which avoids all needless copies when
* 64-bit registers are swapped.
