ParagonIE_Sodium_Core_SipHash:: (4 methods):
  sipRound()
  add()
  rotl_64()
  sipHash24()

Class: ParagonIE_Sodium_Core_SipHash - X-Ref

Class ParagonIE_SodiumCompat_Core_SipHash

Only uses 32-bit arithmetic, while the original SipHash used 64-bit integers

sipRound(array $v) X-Ref

return: int[]
param: int[] $v

add(array $a, array $b) X-Ref

Add two 32 bit integers representing a 64-bit integer.

return: array<int, mixed>
param: int[] $a
param: int[] $b

rotl_64($int0, $int1, $c) X-Ref

return: array<int, mixed>
param: int $int0
param: int $int1
param: int $c

sipHash24($in, $key) X-Ref

Implements Siphash-2-4 using only 32-bit numbers.

When we split an int into two, the higher bits go to the lower index.
e.g. 0xDEADBEEFAB10C92D becomes [
0 => 0xDEADBEEF,
1 => 0xAB10C92D
].

return: string
param: string $in
param: string $key
