 * HISTORY:
13
 *
14
 * 2020-10-03  (Sebastian Pipping)
15
 *   - Drop support for Visual Studio 9.0/2008 and earlier
16
 *
17
 * 2019-08-03  (Sebastian Pipping)
18
 *   - Mark part of sip24_valid as to be excluded from clang-format
19
 *   - Re-format code using clang-format 9
20
 *
21
 * 2018-07-08  (Anton Maklakov)
22
 *   - Add "fall through" markers for GCC's -Wimplicit-fallthrough
23
 *
24
 * 2017-11-03  (Sebastian Pipping)
25
 *   - Hide sip_tobin and sip_binof unless SIPHASH_TOBIN macro is defined
26
 *
27
 * 2017-07-25  (Vadim Zeitlin)
28
 *   - Fix use of SIPHASH_MAIN macro
29
 *
30
 * 2017-07-05  (Sebastian Pipping)
31
 *   - Use _SIP_ULL macro to not require a C++11 compiler if compiled as C++
32
 *   - Add const qualifiers at two places
33
 *   - Ensure <=80 characters line length (assuming tab width 4)
34
 *
35
 * 2017-06-23  (Victor Stinner)
36
 *   - Address Win64 compile warnings
37
 *
38
 * 2017-06-18  (Sebastian Pipping)
39
 *   - Clarify license note in the header
40
 *   - Address C89 issues:
41
 *     - Stop using inline keyword (and let compiler decide)
42
 *     - Replace _Bool by int
43
 *     - Turn macro siphash24 into a function
44
 *     - Address invalid conversion (void pointer) by explicit cast
45
 *   - Address lack of stdint.h for Visual Studio 2003 to 2008
46
 *   - Always expose sip24_valid (for self-tests)
47
 *
48
 * 2012-11-04 - Born.  (William Ahern)

50
 * USAGE:
51
 *
52
 * SipHash-2-4 takes as input two 64-bit words as the key, some number of
53
 * message bytes, and outputs a 64-bit word as the message digest. This
54
 * implementation employs two data structures: a struct sipkey for
55
 * representing the key, and a struct siphash for representing the hash
56
 * state.
57
 *
58
 * For converting a 16-byte unsigned char array to a key, use either the
59
 * macro sip_keyof or the routine sip_tokey. The former instantiates a
60
 * compound literal key, while the latter requires a key object as a
61
 * parameter.
62
 *
63
 *  unsigned char secret[16];
64
 *  arc4random_buf(secret, sizeof secret);
65
 *  struct sipkey *key = sip_keyof(secret);
66
 *
67
 * For hashing a message, use either the convenience macro siphash24 or the
68
 * routines sip24_init, sip24_update, and sip24_final.
69
 *
70
 *  struct siphash state;
71
 *  void *msg;
72
 *  size_t len;
73
 *  uint64_t hash;
74
 *
75
 *  sip24_init(&state, key);
76
 *  sip24_update(&state, msg, len);
77
 *  hash = sip24_final(&state);
78
 *
79
 * or
80
 *
81
 *  hash = siphash24(msg, len, key);
82
 *
83
 * To convert the 64-bit hash value to a canonical 8-byte little-endian
84
 * binary representation, use either the macro sip_binof or the routine
85
 * sip_tobin. The former instantiates and returns a compound literal array,
86
 * while the latter requires an array object as a parameter.
87
 * --------------------------------------------------------------------------
88
 * NOTES:
89
 *
90
 * o Neither sip_keyof, sip_binof, nor siphash24 will work with compilers
91
 *   lacking compound literal support. Instead, you must use the lower-level
92
 *   interfaces which take as parameters the temporary state objects.
93
 *
94
 * o Uppercase macros may evaluate parameters more than once. Lowercase
95
 *   macros should not exhibit any such side effects.
