You can use my PassDialog plugin for secure input:
http://nsis.sf.net/File:PassDialog.zip

I don't understand why you want the installer to generate a random CD key. How is the user going to know what it is if it doesn't stay the same!? Unless you want to create a CD key for each CD distribution, in which case you should write an external executable in VB/C or even NSIS to perform this operation.

i already test passdialog.zip, it has only 1 serial and you will hard code it inside your script. how can i do a random test to all the keys i hard coded on my script. example, i have a 10 key in my script. and if someone install myapp.exe and enter the key, the sequence will check if the inputed key match on any of my serial.

Storing the key in the script is very insecure. Consider using DCryptDll instead (but it's a little more advanced)
