$ openssl ecparam -name P-256 -genkey -noout -out private-key.pem
$ openssl ec -in private-key.pem -pubout -out public-key.pem

and copy to the root folder. You can use the sample ones already there also.

5. Make sure you have http-message-signatures installed.

$ node signed-deposit-example.js

7. You will see the request and response payloads and whether signature and content digest are valid from the output.
