Verify ethereum certificate (ropsten)


I have a problem verifying a certificate generated with cert-issuer.

I’m trying to verify it with its online verifier, but it gives me an error.

In the conf.ini file of the cert-tools project I have this:

And in the conf.ini file of the cert-issuer project:

Thank you


I believe this is a case sensitivity issue, where your issuing_address has some capital letters but from the looks of it, I think most blockchain explorers return back all lowercase addresses. Try lowercasing that issuing_address and see if that helps. Meanwhile, I’ll file a ticket to handle case sensitivity for Ethereum since it doesn’t matter for it.

Edit: Filed a ticket for it here:

@aronning thank you very much, the problem was resolved.

You’re welcome! Just as a FYI, this issue in general has been fixed, the sensitivity of addresses will not cause the cert-verifier-js to fail.

Thank you, its works for me

I’m also facing a similar kind of issue and even tried to change the caps to small letters in the issuing address.

You would need to list the key used to issue this certs in the issuer profile: cert-issuer/profile.json at master · blockchain-certificates/cert-issuer · GitHub
