Authorize

Pull up MYKEY for authentication binding. See the class definition for the parameters:AuthorizeRequest and MYKEYResponse

For greater security, dapp can set CallBackUrl for server-side verification.

MYKEY will post the signed data to CallBackUrl which provided by dapp, server-side of DApp should verify the signature, dapp server should query the user's ReserveKey from MYKEY SmartContract data to verify the signature, see detail in KEYS in MYKEY.

The format of the data post to CallBackUrl:

{
    "protocol":"",  // protocol name，Use init method, protocol name is 'MYKEY', use initSimple to init, protocol name is 'MYKEYSimple'
    "version":"",   // Version，1.0
    "dapp_key":"",  // DAPP_KEY assigned by MYKEY，contact MYKEY team to apply. In simple mode, it is null
    "uuID":"",      // user id，dapp passed it in init method；In simple mode, it is device id
    "sign":"",      // eos signature, sign data：timestamp + account + uuID + ref
    "ref":"",       // ref, mykey
    "timestamp":"", // UNIX timestamp, accurate to second
    "account":"",    // eos account name
    "chain": ""      // value could be ANY, EOS, ETH，or not pass this param
}

Verify signature：

// generate unsignedMessage
let unsignedData = timestamp + account + uuID + ref
// publicKey: ReserveKey of MYKEY，can be quired from SmartContract https://github.com/mykeylab/Documentation/blob/master/English/MYKEY%20on%20EOSIO.md#keys-in-table-keydata
ecc.verify(signature, unsignedData, pubkey) === true

dapp should provide response of CallBackUrl call to MYKEY：

{
    "code":0,       // error code，=0 is success. >0, dapp should describe error in message.
    "message":""    // message
}

Sample：

let authorizeRequest = AuthorizeRequest()
authorizeRequest.userName = "uchihamadara"
authorizeRequest.info = "Test information"
// param：{"protocol": "", "version": "", "dapp_key": "", "uuID": "", "public_key": "", "sign": "", "ref": "", "timestamp": "", "account": ""}
// return: same as SimpleWallet {"code": [0-2], "message": ""}
authorizeRequest.callbackUrl = "https://dappserver.xxx.url"

MYKEYWallet.shared.authorize(authorizeRequest: authorizeRequest, response: MYKEYResponse.init(success: { (response) in
    self.view.makeToast("success")
}, failure: { (errorValue) in
    self.view.makeToast("failure")
}, cancelled: {
    self.view.makeToast("cancelled")
}))
