How to use nacl.secretbox.open(box, nonce, key)? #145

secret-box-issue.js

const decryptFile = (filePath, sKey) => {
  fs.readFile(filePath, 'utf8', (err, data) => {
    if (err) throw err;

    let hash = computeSHA256(sKey);
    let buffer = Buffer.from(hash.toString(CryptoJS.enc.Hex), 'hex');
    let key = new Uint8Array(buffer);

    buffer = Buffer.from(data.toString(CryptoJS.enc.Hex), 'hex');
    let encryptedData = new Uint8Array(buffer);

    let decryptedData;
    try {
      decryptedData = nacl.secretbox.open(encryptedData, Rnonc, key);
    } catch (e) {
      console.log("Error in decryptFile: ", e);
    }

    console.log("DecryptedData: ", decryptedData);
  });
