Hi guys, I am trying to run cert\_issuer using the bitcoin testnet. I edited conf\_regtest with my testnet public key and have run the below command, however I get an error saying I cannot connect to the Bitcoin Service Provider? Any idea how I can fix this? Thanks. **Run Cert\_Issuer** python cert\_issuer -c conf\_regtest.ini **Connection Error** `ImportError: cannot import name BitcoinServiceProviderConnector` ---

A solution that helped me get the cert-issuer to work were the below steps. I am a beginner in programming, so I am sure there is a better way to solve this, but this seemed to work. **Steps to Issue Certificates** 1. Make sure python3 is used 2. Run pip3 install -r requirements.txt (I have to use pip3 as pip is for v2.7 on my machine) 3. Copy issue\_certificates.py and paste in the directory above. If I ran issue\_certificates.py in the original location, I get the error ‘cannot import bitcoin.rpc’. Not sure why this is but this solution seems to help 4. Get a bitcoin tesnet address from [https://bitcoinpaperwallet.com/bitcoinpaperwallet/generate-wallet.html?design=alt-testnet](https://bitcoinpaperwallet.com/bitcoinpaperwallet/generate-wallet.html?design=alt-testnet) . This will give you a public and a private key 5. Get testnet coins from [https://testnet.manu.backend.hamburg/faucet](https://testnet.manu.backend.hamburg/faucet) and send them to your public key (you need to wait for confirmations to go through to receive the funds, this took over an hour for me) 6. Copy config\_regtest.ini and rename it to config.ini. Add in the testnet bitcoin public address and use chain=bitcoin\_testnet and change bitcoind=False 7. Make a new file pk.txt and copy the private key directly into the file and edit the conf.ini file to contain key\_file=pk.txt and usb\_home = 8. Copy some unsigned certificates into the director \data\unsigned\_certificates 9. Run ‘python3 issue\_certificates.py’ ---

Hi Jacke! And Kim! I went through the Cert-Issuer tutorial, and I managed to issue certificates using the docker image in regtest. But Im having a rough time starting with Testnet, do you have any suggestion? Im thinking about following this tutorial, but I have a few questions: 3. What do you mean with “in the directory above” the python directory or the cert-issuer? 6. Copy the config\_regtest.ini and paste it where? 7. Can I have the pk.txt in my hard drive or does it have to be in a USB drive always? Thanks in advanced for all the help!
