# jerry-rigged license system with UUID check (preventing more than one installation) and expiration date



### Tested against Python 3.9.16 (Anaconda) -  Windows 10



#### jerry-rigged???



From https://www.urbandictionary.com/define.php?term=jerry-rig

jerry-rig - To put together in a way that works, but is contrary to the "norm" or specific directions (instructions)



The serial number system can be cracked easily (which one can't?), but it should be secure enough for any average user.



### pip install jerryrigserialgen - if you want to generate serial numbers



### pip install jerryrigserialver - if you want to verify serial numbers (client)





```python

from jerryrigserialgen import Serialgenerator



# Generates serial numbers

# pip install jerryrigserialgen

seri = Serialgenerator(

    product="myproduct",  # Name of the product

    savefolder="c:\\mynicefolder\\new",  # just for the record - files are not needed

    hardcodedpasswort_transfer="topsecret",  # for transfer.sh - must be hard-coded in the app the client uses

    hardcodedpasswort_url="5248614597016233",  # 16 digits to encrypt the URL - must be hard-coded in the app the client uses

    addinformationtoserial=(

        "info1",

        "info2",

    ),  # extra information you want to transmit to the app the client uses

    licensedays=17,  # duration of the license - from today on

    subtract_from_time=0,  # for debugging - to create expired licenses

)

serialnumber, debuginfo = seri.upload()

print(serialnumber) # This is the serial number you are going to give to your client, like: 566978376a4b356956775955427a4779636e533856705a59534d314369387735526e59744230396f6c6771795256675a31365a756947344753616d3757536d5961704f736a362f63506871724a792f3845664d4845773d3d475ac18a6927938b4ede1613058f253e
