Registration.

Input

OutputTrue or False

1: Get cryptographic key pair cryptoKeyPair = createKeyPair();

2: String PublicKey = cryptoKeyPair.getHexPublicKey();

3: String data = AccountId + UserInfo + PublicKey;

4: Get cryptographic suite cSuite = new CryptoSuite (CryptoType.ECDSATYPE);

5: String hashData = cSuite.hash (data);

6: String sigdata = cSuite.sign (hashData, cryptoKeyPair);

7: rec = register (UserInfo, PublicKey, UserInfo, sigdata);

8: response = getRegisterEventEvents (rec);
