* siphash.h - SipHash-2-4 in a single header file
* --------------------------------------------------------------------------
* Derived by William Ahern from the reference implementation[1] published[2]
* by Jean-Philippe Aumasson and Daniel J. Berstein. Licensed in kind.
* by Jean-Philippe Aumasson and Daniel J. Berstein.
* Minimal changes by Sebastian Pipping on top, details below.
* Licensed under the CC0 Public Domain Dedication license.
*
* 1. https://www.131002.net/siphash/siphash24.c
* 2. https://www.131002.net/siphash/
* --------------------------------------------------------------------------
* HISTORY:
*
* 2017-06-10 (Sebastian Pipping)
* - Clarify license note in the header
* - Address C89 issues:
* - Stop using inline keyword (and let compiler decide)
* - Turn integer suffix ULL to UL
* - Replace _Bool by int
* - Turn macro siphash24 into a function
* - Address invalid conversion (void pointer) by explicit cast
* - Always expose sip24_valid (for self-tests)
*
* 2012-11-04 - Born. (William Ahern)
* --------------------------------------------------------------------------
* USAGE:
*
* SipHash-2-4 takes as input two 64-bit words as the key, some number of
* message bytes, and outputs a 64-bit word as the message digest. This
* implementation employs two data structures: a struct sipkey for
* representing the key, and a struct siphash for representing the hash
* state.
*
* For converting a 16-byte unsigned char array to a key, use either the
* macro sip_keyof or the routine sip_tokey. The former instantiates a
* compound literal key, while the latter requires a key object as a
* parameter.
*
* unsigned char secret[16];
* arc4random_buf(secret, sizeof secret);
* struct sipkey *key = sip_keyof(secret);
*
* For hashing a message, use either the convenience macro siphash24 or the
* routines sip24_init, sip24_update, and sip24_final.
*
* struct siphash state;
* void *msg;
* size_t len;
* uint64_t hash;
*
* sip24_init(&state, key);
* sip24_update(&state, msg, len);
* hash = sip24_final(&state);
*
* or
*
* hash = siphash24(msg, len, key);
*
* To convert the 64-bit hash value to a canonical 8-byte little-endian
* binary representation, use either the macro sip_binof or the routine
* sip_tobin. The former instantiates and returns a compound literal array,
* while the latter requires an array object as a parameter.
* --------------------------------------------------------------------------
* NOTES:
*
* o Neither sip_keyof, sip_binof, nor siphash24 will work with compilers
* lacking compound literal support. Instead, you must use the lower-level
* interfaces which take as parameters the temporary state objects.
*
* o Uppercase macros may evaluate parameters more than once. Lowercase
* macros should not exhibit any such side effects.
