"To set this up properly, we need to have a serialize function and a deserialize function. In passport we create these with <code>passport.serializeUser( OURFUNCTION )</code> and <code>passport.dederializeUser( OURFUNCTION )</code>",
"The serializeUser is called with 2 arguments, the full user object and a callback used by passport. Returned in the callback should be a unique key to identify that user- the easiest one to use being the users _id in the object as it should be unique as it generated by MongoDb. Similarly deserializeUser is called with that key and a callback function for passport as well, but this time we have to take that key and return the users full object to the callback. To make a query search for a Mongo _id you will have to create <code>const ObjectID = require('mongodb').ObjectID;</code>, and then to use it you call <code>new ObjectID(THE_ID)</code>.

In this example, we always set the last_login as now, we always increment the login_count by 1, and only when we insert a new object(new user) do we populate the majority of the fields.

"<dfn>Socket.IO</dfn> enables real-time, reliable, speedy communication between your server and clients from all devices and browsers. It listens for connects on your server that come from the client which connects with a single javascript statement. The whole library is based on emitting, broadcasting, and recieving events that contain an event name and some data which can include things like strings, objects, arrays, and even blobs like files or video. This is used for all sorts of purposes including instant messaging online, real-time analytics, streaming, and document collaboration.<br>Start this project on Glitch using <a href='https://glitch.com/#!/import/github/freeCodeCamp/boilerplate-socketio/'>this link</a> or clone <a href='https://github.com/freeCodeCamp/boilerplate-socketio/'>this repository</a> on GitHub!

By setting and configuring a Content Security Policy you can prevent the injection of anything unintended into your page. This will protect your app from XSS vulnerabilities, undesired tracking, malicious frames, and much more. CSP works by defining a whitelist of content sources which are trusted. You can configure them for each kind of resource a web page may need (scripts, stylesheets, fonts, frames, media, and so on…). There are multiple directives available, so a website owner can have a granular control. See HTML 5 Rocks, KeyCDN for more details. Unfortunately CSP in unsupported by older browser.",

Set also the scriptSrc directive so that you will allow scripts to be downloaded from your website, and from the domain 'trusted-cdn.com'.",

"BCrypt hashes are very secure. A hash is basically a fingerprint of the original data- always unique. This is accomplished by feeding the original data into a algorithm and having returned a fixed length result. To further complicate this process and make it more secure, you can also <em>salt</em> your hash. Salting your hash involves adding random data to the original data before the hashing process which makes it even harder to crack the hash.",
"BCrypt hashes will always looks like <code>$2a$13$ZyprE5MRw2Q3WpNOGZWGbeG7ADUre1Q8QO.uUUtcbqloU0yvzavOm</code> which does have a structure. The first small bit of data <code>$2a</code> is defining what kind of hash algorithm was used. The next portion <code>$13</code> defines the <em>cost</em>. Cost is about how much power it takes to compute the hash. It is on a logarithmic scale of 2^cost and determines how many times the data is put through the hashing algorithm. For example, at a cost of 10 you are able to hash 10 passwords a second on an average computer, however at a cost of 15 it takes 3 seconds per hash... and to take it further, at a cost of 31 it would takes multiple days to complete a hash. A cost of 12 is considered very secure at this time. The last portion of your hash <code>$ZyprE5MRw2Q3WpNOGZWGbeG7ADUre1Q8QO.uUUtcbqloU0yvzavOm</code>, looks like 1 large string of numbers, periods, and letters but it is actually 2 seperate peices of infomation. The first 22 characters is the salt in plain text, and the rest is the hashed password!",

Add this into your existing hash function(since you need to wait for the hash to complete before calling the compare function) after you log the completed hash and log 'res' to the console within the compare. You should see in the console a hash then 'true' is printed! If you change 'myPlaintextPassword' in the compare function to 'someOtherPlaintextPassword' then it should say false.",

"Hashing synchronously is just as easy to do but can cause lag if using it server side with a high cost or with hashing done very often. Hashing with this method is as easy as calling <code>var hash = bcrypt.hashSync(myPlaintextPassword, saltRounds);</code>",
"<hr>Add this method of hashing to your code and then log the result to the console. Again, the variables used are already defined in the server so you wont need to adjust them. You may notice even though you are hashing the same password as in the async function, the result in the console is different- this is due to the salt being randomly generated each time as seen by the first 22 characters in the third string of the hash.",
