QUESTION
I'm experimenting with Chaum's blind signature, and what I'm trying to do is have the blinding and un-blinding done in JavaScript, and signing and verifying in Java (with bouncy castle). For the Java side, my source is this, and for JavaScript, I found blind-signatures. I've created two small codes to play with, for the Java side:
...ANSWER
Answered 2021-Dec-13 at 14:56The blind-signature library used in the NodeJS code for blind signing implements the process described here:
BlindSignature.blind()generates the SHA256 hash of the message and determines the blind message m' = m * re mod N.BlindSignature.sign()calculates the blind signature s' = (m')d mod N.BlindSignature.unblind()determines the unblind signature s = s' * r-1 mod N.BlindSignature.verify()decrypts the unblind signature (se) and compares the result with the hashed message. If both are the same, the verification is successful.
No padding takes place in this process.
In the Java code, the implementation of signing the blind message in signConcealedMessage() is functionally identical to BlindSignature.sign().
In contrast, the verification in the Java code is incompatible with the above process because the Java code uses PSS as padding during verification.
A compatible Java code would be for instance:
QUESTION
I'm currently working on a proof-of-concept for a web app that will be used by two users. For this, I'm simulating the process within the terminal (very very basic).
What I'm trying to do is to demonstrate the initial "linking" of the two users. I've created a class for the users with multiple properties. The method setUserInfo() should run step-by-step until the user selects a preference of my list (I'm using the prompt-list npm package for this) and then this selection should be pushed into the array ownPref. After that the method receivePartnerPrefs() should insert the contents of partnerExamplePrefs into the constructor property partnerPrefs.
The problem is, if I run this script, everything is fine until the list.ask() method of the prompt-list package does its thing. Every method after that (in this case receivePartnerPrefs) runs simultaneously and breaks the step-by-step process I'm trying to show here.

QUESTION
const ps = require("prompt-sync");
const prompt = ps();
console.log("\nFinding The Maximum Number In The Array");
console.log("---------------------------------------");
let length = prompt("Enter the length of the array: ");
let temp = 0;
let maxnum;
let array = [];
for(let i=0; i temp){
temp = array[o];
}
if(o == (length-1)){
maxnum = temp;
console.log("\ncurrent max " + maxnum);
}
}
console.log("The maximum number is: "+ maxnum);
ANSWER
Answered 2021-Oct-28 at 11:46prompt gets you string values, and when you compare the string value 10 to 7, then 7 is considered the greater one, because string comparison happens character by character, from left to right.
Use array[i] = parseInt(num); to convert those string values into actual integer values first.

I'm trying to write tic-tac-toe game logic, so I need to take user inputs alternatively from user 'X and user 'O. The first player is chosen by a random function.

QUESTION
I'm not able to return the winner and stop the prompt from asking the input.
...ANSWER
Answered 2021-Sep-21 at 07:29You misunderstood how return works. A return will exit the function it belongs to, and no further code is executed.
If player does not have every field in the first row, you call return null and that will exit the function. So no further tests are done. Neither for the remaining rows nor for the columns or diagonals. So you effectively only test the first row.
You have to remove all return null; and only place one return null; at the end of the function.
You should learn how to use a debugger, and step tough each line of the code to see what is actually happening.
QUESTION
so I am having issues trying to run a program with Node that I have made in javascript im not sure what is wrong and I cant really found out either because it provides no stack or error and just simply ends
...ANSWER
Answered 2021-Jul-02 at 20:58It's not crashing. It's exiting without issue. You initialize loop to 0 and then start an infinite loop while loop is 1 but it's never 1 so it just exits.
Change it from loop=0 to loop=1
QUESTION
I am just beginning with JS and am having trouble with scope and executing code in similar style as I would with Python. I have started learning JS on Codecademy and have just begun my first project.
My code for the project is below:

Answered 2021-May-26 at 08:49Maybe as a starter you can you == rather than === as it would not match the type, also in your else if it seems you are calling function incorrectly, remove =.
QUESTION
I use prompt-sync module in my Node project.
ANSWER
Answered 2021-Jan-22 at 20:47The error is raised because you cannot call a namespace import (* as ns). This restriction is per the ECMAScript specification which mandates that module namespace objects, such as the aforementioned syntax creates, cannot have a [[Call]] or [[Construct]] signature.
This results in a mismatch when attempting to consume CommonJS modules from ES modules as many of the former export a single function or constructor as the module itself (i.e. module.exports = function () {}).
However, there is interop capability specified and conventionalized which works by synthesizing a default export for the CommonJS module that contains the value of module.exports.
You can and should leverage this interop facility.
Firstly, ensure that "esModuleInterop" is specified with a value of true in your tsconfig.json under "compilerOptions".
Secondly, rewrite your code to import the synthetic default from the prompt-sync module
QUESTION
This is my first time making classes in Node.js and I was wondering why I can't run this function.... Can someone point me in the right direction?
...ANSWER
Answered 2020-Sep-20 at 18:56It's a scopped function in the way you made it here... That means you can't "see" it in the scope your trying to access it from.
You need either to make it a "method" or to attach it to "this".
QUESTION
I thought I understood what I was doing until this wasn't going in order. I am running this through Node, not through a browser.
It goes to the prompt at the end of the while loop first. I don't know why.
...ANSWER
Answered 2020-Jul-06 at 04:40It is because fs.readFile is asynchronous, so your second prompt is executing before fs.readFile has finished. You may want to use async functions and await or put the prompt at the end of the callback for jsonReader.
