Problem with Cert-Issuer

Gabalo · June 18, 2017, 9:27pm

Hi,

I’m following the README on the Cert-Issuer github page with the exact same steps.
These are the commands I’m using.

issuer=bitcoin-cli getnewaddress
sed -i.bak “s//$issuer/g” /etc/cert-issuer/conf.ini
bitcoin-cli dumpprivkey $issuer > /etc/cert-issuer/pk_issuer.txt

Note: I didn’t change the conf.ini. I’m using everything exactly as it is on github*

cp /cert-issuer/examples/data-testnet/unsigned_certificates/bc9bdbb5-d734-4242-9edc-d1bc3f8f7a6e.json /etc/cert-issuer/data/unsigned_certificates/

I’m using a sample certificate *

bitcoin-cli generate 101
bitcoin-cli getbalance
bitcoin-cli sendtoaddress $issuer 5
cert-issuer -c /etc/cert-issuer/conf.ini

And here on that last command I’m getting the following (huge) error list:

bash-4.3# cert-issuer -c /etc/cert-issuer/conf.ini

Can someone help me understand why or how to solve this?

Thanks!

This is a problem with the openbadge’s context SSL. I am adding a fix to use only preloaded contexts, to avoid this. The openbadgespec site was down for a couple of days, and now that it’s up, we are also seeing this SSL error.

Thanks for your answer.
I will be waiting for the update.

Regards,
Gabriel

Hi Gabalo,
I just committed this fix. Please let me know if you have any problems with it. Thanks,
Kim
