In this question Erik needs to generate a secure random token in Node.js. There’s the method crypto.randomBytes that generates a random Buffer. However, the base64 encoding in node is not url-safe, it includes / and + instead of - and _. Therefore, the easiest way to generate such token I’ve found is
require('crypto').randomBytes(48, function(ex, buf) {
token = buf.toString('base64').replace(/\//g,'_').replace(/\+/g,'-');
});
Is there a more elegant way?
