/*
|
|
* 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.
