Detailed Description

The PhiloxNxW classes export the member functions, typedefs and operator overloads required by a CBRNG class.

As described in Parallel Random Numbers: As Easy as 1, 2, 3 . The Philox family of counter-based RNGs use integer multiplication, xor and permutation of W-bit words to scramble its N-word input key. Philox is a mnemonic for Product HI LO Xor).

r123::Philox2x32

Philox2x32 is equivalent to Philox2x32_R<10>. With 10 rounds, Philox2x32 has a considerable safety margin over the minimum number of rounds with no known statistical flaws, but still has excellent performance.

r123::Philox2x64

Philox2x64 is equivalent to Philox2x64_R<10>. With 10 rounds, Philox2x64 has a considerable safety margin over the minimum number of rounds with no known statistical flaws, but still has excellent performance.

r123::Philox4x32

Philox4x32 is equivalent to Philox4x32_R<10>. With 10 rounds, Philox4x32 has a considerable safety margin over the minimum number of rounds with no known statistical flaws, but still has excellent performance.

r123::Philox4x64

Philox4x64 is equivalent to Philox4x64_R<10>. With 10 rounds, Philox4x64 has a considerable safety margin over the minimum number of rounds with no known statistical flaws, but still has excellent performance.
