How do i generate corda nodes keystores in dev mode

+1 vote

In corda dev mode, does a new identity certificate generates every time it starts up? How is the new identity certificate signed by the certificate authority?

In Corda, the node will look into its keystore to check if it already has an identity certificate, and if it doesn't, then it gets created automatically. 

This is done by adding the following line to each node's node.conf file:

devMode : true

 A hardcoded test root CA is used to sign these certificates for dev purposes.

Once the keystore and certificates have been generated, you can turn off dev mode if you want. You do this by stopping each node, setting

 devMode : false

and then restarting each node.

Outside of dev mode, the node will expect the relevant certificates to already exist in its keystore, and will throw an exception if they don’t exist.

The solution didn't work for me. I am using corda 4.0. The node start-up takes very long time without completion. Further the node is unable to load any cordapps. Please suggest any solution.
Are you getting any errors while loading cordapps?
