Hello Forum,

we would like to protect our Python script.
How do we get the serial number out of C4D, so that we can limit the Script to our customers?

Some code snippets would be appreciated...

Kind regards,
Ronald

Scripts (expressions and Commands) cannot be protected. You need to make plugins of them to -somewhat- protect
them using the Scripts ->"Source Protector..." command in Cinema.

Das muss gehe!

import c4d
from c4d import gui
#Welcome to the world of Python

def main() :
gui.MessageDialog('Hello World!')

si = c4d.GeGetSerialInfo(c4d.SERIALINFO_MULTILICENSE)
    if len(si['nr']) > 0:
        # Multi-license, do something
        print "Multi-license"
        print si
    else:
        si = c4d.GeGetSerialInfo(c4d.SERIALINFO_CINEMA4D)
        print "Single-license"
        print si
        # Single-license, do something

if __name__=='__main__':
main()

Thit code works fine!
But:
I need te eleven digits from the right
like in EXCEL "right(si,11)".
This could be compaired with something.
If the result is "true" the Phyton-Script would be executet.

With the Souce-protector the Script should be protected.
Kind regards
Ronald

Hi, as tcastudios said only Python Plugins can be protected. Scripts can not be encrypted.

Cheers, Sebastian

Everything in my plugin works greate
Only on last Problem:

The serialchek never turns to the ok???
I've filtert the serialnumber,only the 11 numbers to a varriable.
Then i Compare it with a number.
But it never runs through the "true" - part
Could it be that I compare a sting with a number?
How can I solve the problem?

Thanks to all here

Well, according to how I read your code, you're comparing the variable 'sn' which is a string to the string constant 'SERIENNUMMER' which is a different string. So it will always fail.

What you should be doing is taking the plugin serial number your user entered and somehow getting the C4D serial out of that so you can compare it to 'sn'. How you do that depends on how you generated the serial number in the first place, and only you know that. But you would normally generate a plugin serial from the 11 digits of the user's C4D serial which they send you when they buy a licence.

Of course, f you are going to give this plugin away then you don't need to do any serial checking at all.

Hi Spedler,
you are wright.
I want to type my serial number in the variable at the beginning.
Then ich want to compare it with the serialnumber of my license.
The print sn and print SERIENNUMMER shows the same values in the console.
But: the compare (sn == SERIENNUMMER) retuns a false!!!
Do you know why?

Thanks a lot

Beats me then, sorry. I don't use Python but I would have thought that your code should work.

Ok, i found something:
one is string and one is long!
So: how can I check the type of a varriable and how can I convert it.

Thanks a lot

The serial number returned by GeGetSerialInfo returns a string, so you either have to declare the SERIENNUMMER variable as a string (by putting the digits in quotes) or you can typecast sn to an integer with int(sn).
I recommend the latter.

  
  
SERIENNUMMER = 14300012345   
  
def check_serialinfo() :   
    si = c4d.GeGetSerialInfo(c4d.SERIALINFO_CINEMA4D)   
    print "Single-license"   
    sn = si['nr']   
    print sn   
    print SERIENNUMMER   
    if (int(sn) == SERIENNUMMER) :# !!! here was the problem!!!   
        print 'ok'   
    else:   
        print 'not ok'   
    # Single-license, do something   
    print 'Seriennummerncheck beendet'
