New page

<pre>
RandomSeed( <flag> )
</pre>

=== Description ===

Generator a cryptographically strong random number for use as a seed.

=== Parameters ===

== flag ==

Optional; Type of random number to generate.

<pre>
0 = Generate a random unsigned Int32
1 = Generate a random unsigned Int64
</pre>

Default: 0

=== Return Value ===

Success: Returns a cryptographically strong random number.

Failure: Return null.

=== Remarks ===

This uses the the .NET RNGCryptoServiceProvider to do the generating.

You can use the return value for anything that needs a good seed.

This can also be used to generate random numbers but RandomVar() is more generic for that task.

==== Example ====

<syntaxhighlight lang="sputnik">
$random = RandomSeed(); // 32 Bit
$random = RandomSeed(1); // 64 Bit
</syntaxhighlight>
