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;
}
