Hello @Gabalo,
you are right, you had to change the issuer_public_key to the one you were using in the cert-issuer. But don’t miss the “ecdsa-koblitz-pubkey:”. The entry has to look like this, but replace “” with your public key:
issuer_public_key=ecdsa-koblitz-pubkey:<your-public-key>
Another problem is that the verification is looking up the issuer id. See also https://github.com/blockchain-certificates/cert-verifier-js#check-certificate-authenticity and https://github.com/blockchain-certificates/cert-verifier-js#issuer-identity. This means that you have to change theissuer_id in the conf.ini. Currently it points to a JSON file containing a public key (beside other information) which does not math your public key used in cert-issuer. Host your own JSON file somewhere and point the issuer_id to the address in order to fix the authenticity check.
Kind regards,
uzu
