did module is help developer to implement DID protocol easily.

did module provide four kinds of Claim : profile, agreement, sign and did.

profile type can require client return user's profile such as: username, phone or avatar

agreement type sent a doc to user so user can signature it and return it.

Signature type provide a origin transaction, If user want to sent this transaction ,just need signature this transaction and return result.

did type require user to provide an asset or an account DID to proof he match some case. such as: proof his account has enough Token or he has a target asset.

first, you have to create a api for client to query claim. and put it as a parameter of https://abtwallet.io/i/ and use this url to generate a QR code which can be scan by Wallet App.

In this api, you have to claim what information your application really want.

    //declare your application app info
    val appInfo = AppInfo()
    //declare a claim
    val claim1 = ProfileClaim(MetaInfo("profile info",""),arrayListOf("username","email"))
    //the wallet info of your application
    val wallet = WalletInfo("zXXXXXXXX")
    // get the JWT token of claims
    val token = DidAuthUtils.createDidAuthToken(arrayOf(claim1),appInfo,System.currentTimeMillis(),wallet)
    //return response to client
    return DidResponseBody(wallet.pkBase58(),token)

and the Wallet App will feedback user's PK and another jwt token contains information which you have claimed.

{
  "userInfo": "eyJhbGciOiJFZDI1NTE5IiwidHlwIjoiSldUIn0.eyJleHAiOiIxNTU3NzM0Mzk5IiwiaWF0IjoiMTU1NzczDMzOSIsImlzcyI6ImRpZDphYnQ6ejFrWEc3emdOVlFnZ0p4OHJSUXB2b0hYQ1dKbjd5bmF0eEQiLCJuYmYiOiIxNTU3NzM0MzM5IiwicmVxdWVzdGVkQ2xhaW1zIjpbeyJ0eXBlIjoicHJvZmlsZSIsImZ1bGxOYW1lIjoicCJ9XX0.MkE_pvfNyN_7r3MqRYDPSUAfg6GwSW_CofRJtn8a9k25FBE7zuR1zq0rBegTeSTEQTn1OIaZq-N5Coa6XQMoDQ",
  "userPk": "z8ovDmcoZzw6vfszgjfLQgtGncCJvMzaADbvvq7j3SBHe"
}

you can use DidAuthUtils.parseJWT(token) to get your result. before you handle the information, you have to verify JWT.
