* t1ha = { Fast Positive Hash, aka "Позитивный Хэш" }
|
|
* by [Positive Technologies](https://www.ptsecurity.ru)
|
|
*
|
|
* Briefly, it is a 64-bit Hash Function:
|
|
* 1. Created for 64-bit little-endian platforms, in predominantly for x86_64,
|
|
* but portable and without penalties it can run on any 64-bit CPU.
|
|
* 2. In most cases up to 15% faster than City64, xxHash, mum-hash, metro-hash
|
|
* and all others portable hash-functions (which do not use specific
|
|
* hardware tricks).
|
|
* 3. Not suitable for cryptography.
|
|
*
|
|
* The Future will Positive. Всё будет хорошо.
|
|
*
|
|
* ACKNOWLEDGEMENT:
|
|
* The t1ha was originally developed by Leonid Yuriev (Леонид Юрьев)
|
|
* for The 1Hippeus project - zerocopy messaging in the spirit of Sparta!
