# true randomization

## Recommended Posts

the only form of random number gen i can think of is.

```dim \$n
\$n=Random(1,10,1)```

and even that is not exactly random because most of the hits are 1-5. once in a while i get more.

is there anything more random then Random()? (see what i did there? ;D)

Hi,

as you can see:

```#include <array.au3>

Dim \$arrandom [11] [2]
For \$i = 1 To 10
\$arrandom [\$i] [0] = \$i
\$arrandom [\$i] [1] = 0
Next
\$count = 0
While \$count <= 100000
\$n=Random(1,10,1)
\$arrandom [_ArraySearch (\$arrandom, \$n)] [1] = \$arrandom [_ArraySearch (\$arrandom, \$n)] [1] + 1
\$count += 1
WEnd
_ArrayDisplay (\$arrandom)```

i will get at least about 10000 for each number.

;-))

How random does it need to be? You could record the mouse movements of the user, I guess that's the closest to true randomization there is. (this method is also used by Putty)

Random() is good. You are interpreting something wrong when you say that.

Run this to see how 'random' is Random():

```#include <Array.au3>

Global \$iNum
Global \$aArray[11]

For \$i = 1 To 200000
\$iNum = Random(0, 10, 1)
\$aArray[\$iNum] += 1
Next

_ArrayDisplay(\$aArray)```

Question is what do you see when that array is displayed to you.

as random as possible. there will be not much mouse moves... i think...

also, i don't know how to record mouse movements XD;;

Of course, replace "random" by pseudo-random everywhere.

AFAIK the algorithm implemented by AutoIt Random() is excellent and passes whatever test you need for layman applications.

OTOH if you feel you need cryptographic-level pseudo-random input, then rely on proven layers. But do you really need that?

I wouldn't bet my life (nor yours) on how "random" mice movements can be. That's in my view a very bad choice compared to a well know algorithm with proven track record and demonstrated properties.
