Getting stuck while creating keys about crystals-kyber-javascript HOT 7 CLOSED

Please provide details of your platform and running environment.

from crystals-kyber-javascript.

I have tried the upper code in multiple envs like docker containers.
Steps to reproduce:

1. install node
2. npm install crystals-kyber
3. create index.js with upper code
4. add "type": "module" in package.json
5. node index.js

@antontutoveanu help?

I have been able to run the code using node kyber768.js for example.

I believe there is some npm issues which I plan on getting around. Apologies for delays.

I had the same issue, getting stuck at KeyGen, after some digging found that the culprit was this line:
for (let j = start; j < start + l; j++).

For some reason in the source code from the npm package the j was declared twice: at the beginning of the ntt function and in the for loop again. After removing the let in the for loop it worked. Github source code didn't have this issue though.

... same bug in nttInverse function where the j was declared twice (again only in npm's source code).

Also, ArrayCompare was missing in npm code which I just copied over from Github.

I have updated the code on both GitHub and NPM.

Please check again with the following usage:

// Import package
const kyber = require('crystals-kyber');

// To generate a public and private key pair (pk, sk)
let pk_sk = kyber.KeyGen768();
let pk = pk_sk[0];
let sk = pk_sk[1];

// To generate a random 256 bit symmetric key (ss) and its encapsulation (c)
let c_ss = kyber.Encrypt768(pk);
let c = c_ss[0];
let ss1 = c_ss[1];

// To decapsulate and obtain the same symmetric key
let ss2 = kyber.Decrypt768(c,sk);

// Test function with KATs
kyber.Test768();
