Register Signing Key

Data stored offchain are all signed with a signing key belonging to each user. Users will need to create a ECDSA P256 (also known assecp256r1 and ES256) key pair to operate on CyberConnect’s decentralized data store with sovereignty.

Here is the reference doc Proof of Connection.

Workflow

To create a key pair, you could use the following openssl command.

1. Generate public and private keys.

openssl ecparam -genkey -name prime256v1 -noout -out private.pem
openssl ec -in private.pem -pubout -out public.pem

-----BEGIN EC PRIVATE KEY-----
MHcCAQEEIBsl8YngX7uLkp8yWQcdHjceD4FKYpUi6zsnaLrMOsU3oAoGCCqGSM49

/vUHUopa8U7HEDD1MiNFyYuspYfZgRkc7A==
-----END EC PRIVATE KEY-----

-----BEGIN PUBLIC KEY-----

o9St2B8gvrhwW3GxcoGELL4a/vUHUopa8U7HEDD1MiNFyYuspYfZgRkc7A==
-----END PUBLIC KEY-----

2. Send registerSigningKey request.

Run in Postman:

QueryExample

Use this persona access token in HTTP header Authorization . Don’t miss the bearer in front.

{
    "Authorization": "bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJjaGFpbl9pZCI6MSwiZG9tYWluIjoiY3liZXJjb25uZWN0Lm1lIiwiYWRkcmVzcyI6IjB4OTI3ZjM1NTExNzcyMWUwRThBN2I1ZUEyMDAwMmI2NUI4YTU1MTg5MCIsImlzcyI6IkN5YmVyQ29ubmVjdCIsImV4cCI6MTY2NTA4NDU2MywiaWF0IjoxNjYyNDkyNTYzfQ.X3Y-gTTnsmpNRqkZ3vAAv3UOnHBb5WH5EZ2sOcJRPnw"
}

Next Step

Keep your private key for later use (Sign follow and unfollow messages).
