New Cert and Key splitting method.

[hbldh]

• pybankid version: 1.3.0
• Python version: 3.7+
• Operating System: All

Description

The split_certificate method in bankid.certutils could not extract useable PEM client certificate and private key from the 2024-06-10 pfx. Analyse why and write new methods for splitting certificates.

What I Did

The workaround was to copy the certificate part from the released pem file (https://www.bankid.com/en/utvecklare/test#certificate-for-test) to a separate file and the decrypt the key using this method:

openssl.exe pkey -in .\FPTestcert5_20240610.pem -out .\FPTestcert5_20240610_key.pem
