My conf.ini file looks like this–

issuer information

issuer_url = https://www.collegeURL.com/
issuer_email = college@issuer.org
issuer_name = College X
issuer_signature_lines={“fields”: [{“job_title”: “Professor”,“signature_image”: “images/issuer-signature.png”,“name”: “Professor X”}]}

certificate information

certificate_description =This Certificate verifies that the certificate is genuine.
certificate_title = Certificate of Authenticity
criteria_narrative=details are genuine and verified.
badge_id = 7aecc414-ee70-4fe8-952f-2be7d037d61e

images

issuer_logo_file = images/My_LOGO.png

images/logo.png

cert_image_file = images/certificate-image.png
issuer_signature_file = images/issuer-signature.png

###################

TEMPLATE DATA

###################

data_dir = sample_data

template output directory

template_dir = certificate_templates
template_file_name = test.json

##############################

INSTANTIATE BATCH CONFIG

##############################
unsigned_certificates_dir = unsigned_certificates
roster = rosters/roster_testnet.csv
filename_format = uuid
no_clobber = True

So basically How can I generate a new issuer_id?

fill in issuer-id as the url where you are hosting the issuer json. For example
issuer_id = “https://www.collegeURL.com/issuerJSON”

Hi @ampatt97

Thanks for your reply.

I understood I need to generate this issuer.json file & host it on the web/localhost.
I believe it can be generated using following command. " python create_v2_issuer.py -c conf-ini -o issuer.json "

But for this I would be needing a issuer_public_key.

So How can I generate this issuer_public_key?

Many Thanks

Hi @ampatt97
I generate mine through Bitcoin Core. With it i can generate wallets and addresses for every chain (regtest, testnet and mainnet)
I don’t know if there is a more convenient method too :thinking:

You can use https://www.myetherwallet.com/ . It is very convenient to use.

Generate, get the public key and download the private key and follow the create issuer parameters to pass the pk folder and file name

Great , Thanks a ton. I generated this now.

Hi, could you share some more details on what you did after generating a public and private key for Ethereum? Did you simply add issuer_public_key=0x...21? Where do you add a private key folder and file name?

Hi @pranayperiwal,

You need to adjust your conf.ini to highlight the private and public key location.

setting the issuing address property gives you the public key:

issuing_address=0x40Cf9B7DB6FCc742ad0a76B8588C7f8De2b54a60

and then the private key should be written in the file of your choosing, in my case:

key_file=pk_issuer.txt
