Error Handling
If you are getting errors similar to what’s shown below, then make sure to install nodejs version which is “Recommended For Most Users” on nodejs website, and not the “Latest Features” version. After installing the correct version of nodejs, run npm install
node:internal/crypto/hash:67
this[kHandle] = new _Hash(algorithm, xofLen);
^

}Final tip: You can derive public key using your secret key, but you can not derive secret key using your public key.
