Dfns Golang SDK Example

This example gives an example on how to use the dfns api http.Client along with a creadentials signer (here AsymmetricKeySigner).

This example performs two different requests, one with a challenge signing to create a wallet, and one without to retrieve wallet balance.

To run the example, you need to provide a config.yaml (see config.yaml.example) or/and the right environment variables (here for simplicity we use a .env file but it's not mandatory). Copy the config.yaml.example and set the following values:

api:
  appId: "the `App ID` from above"
  authToken: "the `authToken` from above, the value should start with `eyJ0...`"
  baseUrl: "https://api.dfns.wtf"

keySigner:
  privateKey: >
   the private key from the step 'generate a keypair', the newlines should not be a problem
  credId: "the `Signing Key Cred ID` from above"
  algorithm: "The algorithm used by keysigner to prehash message for ecdsa and rsa"

All these values can be overriden by encironment variable with the following pattern: DFNS_API_FIELD or DFNS_KEYSIGNER_FIELD (All should be uppercase) (see .env.example) You can choose to use only environment variables.

then

> cd cmd/dfns_example
> go run *.go
