Re: Crypting data

Hello again

forgive me i made a mistake. It was late in the evening when i wrote
the question and early in the morning when i replyed :)

As i allready wrote i allready sign the data. So its not possible to
change the data only if one have the public key. Of course the public
and private keys are defined the the app running at the customer and
my app to generate the license has only the public key.
This means someone who likes to generate data would need to debug the
app running at the customer and identify the RSA public key inside the
code. Someone who is able to do this should also be able to remove the
licensing completly :)

So forget about the question :) was my false.


Thanks

Hello Will

thanks for your answer.

I need to transfer license data to the customer.This is a normal
cycle:
- costomer creates a license request including name and cpuID
- customer sends that file to me
- i create a license file for that specific cpu-id and name
- i send the license to the customer.

First of all i know this is not secure in means of beeing cracked,
independently of what technic i use. The easyest way for the customer
to break the code would be to install the requiered software under
