Error: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

[grzegorzSowa3]

Hi, I am getting error: SEC_ERROR_REUSED_ISSUER_AND_SERIAL (Firefox 107.0 , Windows 10)
`An error occurred during a connection to www.facebook.com. You are attempting to import a cert with the same issuer/serial as an existing cert, but that is not the same cert.

Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL`
Do you have any idea how to fix that? :)

Hey. A question: are you installing mitm's generated certificates?

[grzegorzSowa3]

Yes, I took root CA .pem file and added it to trusted CAs in the browser.
The issue might be in serial_number: int = random.randint(0, 2 ** 64 - 1) as a default function argument - I verified it generates random number just once and then it is always the same (I'm using Python 3.10.4).
However, when I changed that I must have broke something else, so now I am getting SEC_ERROR_BAD_SIGNATURE

Ah, good catch. I'll push a fix up.

Fixed added in #24. Version 1.4.2 is now live on PyPi.

pip install --upgrade mitm

Thank you for the bug report.
