Hi,
I’m trying to issue some certificates in the testnet of Bitcoin, so I followed the documentation: I installed everything and I solved some intermediate problems, I created an issuing-addres for testnet and I have enough funds to issue a certificate. The certificates I’m trying to issue are those in the example folder, so I moved them into /data/unsigned_certificates. When I execute the command “python cert_issuer -c conf.ini” I’m getting an error saying "hashed base58 has bad checksum ". Well, in fact, I’m executing “sudo python3 cert_issuer -c conf.ini”. The complete response I get is the following:

Does anybody know why am I getting this error and how can I fix it?
Thank you.
