KeyVerification example does not work

[vkhazin]

Documentation: https://github.com/Cryptolens/cryptolens-python#key-verification

Running as-is produces the following response: python ./main-sample.py -> The license does not work: Unable to authenticate.. Possibly, the token is no more valid -> update the documentation

Replacing product key IYVOO-JCWXQ-LCRBI-ZAIQZ as documented in getting started: https://help.cryptolens.io/getting-started/create-license produces the following response: python ./main-sample.py -> The license does not work: Unable to authenticate.. Possibly, the token is no more valid -> update the documentation

Replacing access token with my own: The license does not work: Could not find the product.
An understandable mismatch between access token, the public key and product id.

Replacing public key, access token, product id, and product key with my own produces the following response: python ./main.py -> The license does not work:

@vkhazin thanks for submitting the issue!

From the additional information I received from you by mail, it seems that the problem is in the configuration of the license. More specifically, the root of the error seems to be that the license has "max number of machines" set to 0, which prevents devices from being registered (i.e. it disables node-locking). As a result, Helpers.GetMachineCode fails because it does not detect the device in the list of ActivatedMachines. To fix this, you can either remove Helpers.GetMachineCode or set "max number of machines" to a value greater than 0.

Please let us know should you have any other questions 👍

I have updated the license to 10 machines and that did not change the outcome of the test.

@vkhazin

Could you please try to remove Helpers.IsOnRightMachine after calling Activate. Since empty string is currently being passed during activation, Helpers.IsOnRightMachine will not work.

If you are testing it on Windows, you can switch back to set MachineCode=Helpers.GetMachineCode() and it should work with Helpers.IsOnRightMachine.

I have tried removing the machine code and replacing it with None, different errors no progress: ``` result = Key.activate(token=auth,\ rsa_pub_key=RSAPubKey,\ product_id=product_id, \ key=product_key,\ machine_code=None) ``` ``` The license does not work: ``` ``` result = Key.activate(token=auth,\ rsa_pub_key=RSAPubKey,\ product_id=product_id, \ key=product_key) ``` ``` Traceback (most recent call last): File "./main.py", line 13, in <module> key=product_key) #,\ TypeError: activate() missing 1 required positional argument: 'machine_code' all-power-user:~/environment/cryptolens.io $ ``` Ironically the web console shows an increment of the licenses used, while the python code reports an error: [image: Screen Shot 2020-11-24 at 2.13.01 PM.png]

@vkhazin

When you executed the code below, what was the value of result[0] and result[1]?

result = Key.activate(token=auth,\
                   rsa_pub_key=RSAPubKey,\
                   product_id=product_id, \
                   key=product_key,\
                   machine_code=None)

/Artem

Here is what I get result = Key.activate(token=auth,\ rsa_pub_key=RSAPubKey,\ product_id=product_id, \ key=product_key, \ machine_code=None) print(f"The license does not work, result[0]: {result[0]}, result[1]: {result[1]}") The license does not work, result[0]: <licensing.models.LicenseKey object at 0x7f24bc895d30>, result[1]:

Thanks @vkhazin

From the result, it seems like everything is working (i.e. it is able to obtain a license and does not thrown an error).

It's most likely because of an if statement after the call to Key.activate. Could you please send the code that comes afterwards?

[vkhazin]

There is no code afterwards, I am running the sample code to confirm that the validation of license works. Based on the sample code provided here: https://github.com/Cryptolens/cryptolens-python#example the license is invalid. Either the documentation is incorrect or the sample code is invalid or the license is invalid.

@vkhazin If possible, could you please send us the exact code to support@cryptolens.io with all the parameters. This will help us to tell exactly what's wrong.

From the code and the results that you sent earlier, the response is as expected, and the error most likely lies in the code that comes after the call to activate.
