B4J Question Generate strong random string

[devmobile]

Hello
In my project,i need generate random string code about 1 million records
I can generate random code with RandomLibrary in php and it is very powerful library
But do we have library looklike php library in b4j?

Sub GenerateRandomString (Length As Int) As String
   Dim su As StringUtils
   Dim bytes(Length) As Byte
   SecureRandom1.GetRandomBytes(bytes)
   Return su.EncodeBase64(bytes).SubString2(0, Length)
End Sub

SecureRandom1 is a SecureRandom global variable (jEncryption or Encryption libraries).

Being it RANDOM it will be very difficult to create the SAME string more than ONCE!

I don't get it, what exactly do you want to do?
1- create 1Million different and Randing Strings
or
2- create 1random string a populate 1Million records with it?
