New page

<pre>
RandomSeedSet( <seed> )
</pre>

=== Description ===

Set the seed of Sputniks random number generator

=== Parameters ===

== seed ==

New seed to use for all future random number generations Sputnik does.

=== Return Value ===

Success: Returns a cryptographically strong random number/binary array.

Failure: Return null.

=== Remarks ===

You can use RandomSeed() to generate a cryptographically secure seed or provide your own.

==== Example ====

Set Sputniks RNG seed to a cryptographically secure random number

<syntaxhighlight lang="sputnik">
$Seed = RandomSeed();
RandomSeedSet($Seed);
say RandStr(10);
// Prints
// esehltkajk
</syntaxhighlight>

Changing Sputniks RNG seed will cause all functions that use the RNG to be effected for example here RandStr() is returning the same text every time since we keep setting the seed to same value

<syntaxhighlight lang="sputnik">
$i = 0;
while($i++ < 3)
{
RandomSeedSet(777);
say RandStr(10);
}
// Prints
// qfqg5678k3
// qfqg5678k3
// qfqg5678k3
</syntaxhighlight>
