How do I hide specifically "private_key" from being viewed by everyone as everything is getting stored on the array publically including private_key?
I want to display all the data like address,user Id,first name,last name to be viewed by everyone on the blockchain except for the private_key.
struct User {
address wallet_address;
string userId;
string first_name;
string last_name;
string email_id;
bool set;
string private_key;
}
mapping(address => User) users;
mapping(string => address) walletAccount;
mapping(address => uint) public balanceOf;
User[] public registeredArray;
function createNewUser(address userAcc,string memory _id,string memory firstName,string memory lastName,string memory emailId,string memory _private_key) public {
User storage user = users[userAcc];
users[userAcc] = User(userAcc,_id,firstName,lastName,emailId,true,_private_key);
walletAccount[emailId] = userAcc;
registeredArray.push (users[userAcc]);
}
function getAllUsers()public view returns(User[] memory){
return registeredArray;
}
