Youโ€™ll need to complete the following configurations on the server where the callback server is deployed:
  • Generate the callback serverโ€™s RSA private key
openssl genrsa -out callback-server-pri.pem 4096
  • Export the callback serverโ€™s RSA public key
openssl rsa -in callback-server-pri.pem -pubout >callback-server-pub.key
  • Copy the exported RSA public key (i.e. the callback-server-pub.key file) to the server where the TSS Node is deployed
  • Copy the RSA public key of the TSS Node to the configuration files of the callback server
  • If you use the callback server codes provided by Cobo Custody, please refer to the configuration instructions in the samples
  • After youโ€™ve successfully completed TSS Node initialization, execute the following command to query the RSA public key of the TSS Node:
sudo ./tss-node.sh info
Output example: 
INFO[2022-12-14T07:09:44Z] Callback public key:
