53 * This is a generic 32 bit "collector" for message digest algorithms.-
54 * Whenever needed it collects input character stream into chunks of-
55 * 32 bit values and invokes a block function that performs actual hash-
56 * calculations.-
57 *-
58 * Porting guide.-
59 *-
60 * Obligatory macros:-
61 *-
62 * DATA_ORDER_IS_BIG_ENDIAN or DATA_ORDER_IS_LITTLE_ENDIAN-
63 * this macro defines byte order of input stream.-
64 * HASH_CBLOCK-
65 * size of a unit chunk HASH_BLOCK operates on.-
66 * HASH_LONG-
67 * has to be at least 32 bit wide.-
68 * HASH_CTX-
69 * context structure that at least contains following-
70 * members:-
71 * typedef struct {-
72 * ...-
73 * HASH_LONG Nl,Nh;-
74 * either {-
75 * HASH_LONG data[HASH_LBLOCK];-
76 * unsigned char data[HASH_CBLOCK];-
77 * };-
78 * unsigned int num;-
79 * ...-
80 * } HASH_CTX;-
81 * data[] vector is expected to be zeroed upon first call to-
82 * HASH_UPDATE.-
83 * HASH_UPDATE-
84 * name of "Update" function, implemented here.-
85 * HASH_TRANSFORM-
86 * name of "Transform" function, implemented here.-
87 * HASH_FINAL-
88 * name of "Final" function, implemented here.-
89 * HASH_BLOCK_DATA_ORDER-
90 * name of "block" function capable of treating *unaligned* input-
91 * message in original (data) byte order, implemented externally.-
92 * HASH_MAKE_STRING-
93 * macro convering context variables to an ASCII hash string.-

319 * This comment was originaly written for MD5, which is why it-
320 * discusses A-D. But it basically applies to all 32-bit digests,-
321 * which is why it was moved to common header file.-
322 *-
323 * In case you wonder why A-D are declared as long and not-
324 * as MD5_LONG. Doing so results in slight performance-
325 * boost on LP64 architectures. The catch is we don't-
326 * really care if 32 MSBs of a 64-bit register get polluted-
327 * with eventual overflows as we *save* only 32 LSBs in-
328 * *either* case. Now declaring 'em long excuses the compiler-
329 * from keeping 32 MSBs zeroed resulting in 13% performance-
330 * improvement under SPARC Solaris7/64 and 5% under AlphaLinux.-
331 * Well, to be honest it should say that this *prevents*-
332 * performance degradation.-

337 * Above is not absolute and there are LP64 compilers that-

339 * pre-processor condition reflects the circumstances under which-
