HxD is fantastic in the version 2.1 !!!! Thanks and congratulations!

One quick question. In the "Fill Selection" with "Random Bytes", what is the RNG method or API used by HxD ?

## RNG question

### Re: RNG question

It's from the Delphi runtime library:

RandSeed is initialized with time-like values:

Code: Select all

```
// Random integer, implemented as a deterministic linear congruential generator
// with 134775813 as a and 1 as c.
function Random(const ARange: Integer): Integer;
var
Temp: Longint;
begin
Temp := RandSeed * $08088405 + 1;
RandSeed := Temp;
Result := (UInt64(Cardinal(ARange)) * UInt64(Cardinal(Temp))) shr 32;
end;
```

Code: Select all

```
procedure Randomize;
var
Counter: Int64;
begin
if QueryPerformanceCounter(Counter) then
RandSeed := Counter
else
RandSeed := GetTickCount;
end;
```
