Overload List

FromKey(ReadOnlySpan<UInt32>) Creates a new Philox4x32 instance with the specified key and counter initialized to zero.
FromKey(ReadOnlySpan<UInt32>, ReadOnlySpan<UInt32>) Creates a new Philox4x32 instance with the specified key and counter.

FromKey(ReadOnlySpan<UInt32>)

Creates a new Philox4x32 instance with the specified key and counter initialized to zero.
C# 
public static Philox4x32 FromKey(
	ReadOnlySpan<uint> key
)

Parameters

key  ReadOnlySpan<UInt32>
The 64-bit key (2 × 32-bit words).

Parameters

key  ReadOnlySpan<UInt32>
The 64-bit key (2 × 32-bit words).
counter  ReadOnlySpan<UInt32>
The 128-bit counter (4 × 32-bit words).
