All right, so welcome back again. So in this first class session, we try to see how to build a very simple CLR with Command J s, right, so this project, so let's see what we build in a very simple COI to be able to cipher or decipher a test. So let's see what we put in. So it's going to be node, the name of the app is called cipher. Right? Well, good.

I just hope I'll be able to see the various ways I can use this simple sealer. Very interested, it is safe to lie. So you can check for division, which is going to keep us patient 0.1. Version. Perfect, right 0.01. Now let's see some beauties can also do can rotate a test.

From here, we can rotate, you can also do a scissor shift, you can do a reverse of a test. We can also do it right to convert a test to delete. So let's take the easy stuff you can do with it. So I'll just close this, go back to the help. So I can have it as a reference is routed to a simple test using route taking is going to center like this. Good roots dating in our past in a particular day.

So let's do it. Like Hello. But we tell we're going to rotate it. So don't give us the original test. And then they rotated, right? Very interesting.

Can also do some other stuff like rotating by a number. Let's try that one. So this is rooted. Hello, right and give us this. What's lovely is I want to rotate by Hannah number two is going to be greeted by this Hello, right by number. Taking a greeting to Kentucky was almost the same thing, right?

Because you're sitting by taking I don't rotate by let's see 15 for those who give us a different number. Very interesting, right. So that is the basic idea behind our rotation. Very, very interesting, right? We have rotated by this particular option. Now let's see some other stuff to do.

In case I also want to not only just rotate but I want to convert it to see that shift. Or I can also do the same thing. So let's try that one. So I can just go with my cedar shift. Policies right for cedar shift. Now go to setup.

Go to list how it works, right, so there's going to be a shift just go to the long format, or the short command and it's going to work perfectly fine, you're good the same thing in our supply the particular value. So let's get the value us Let's see, a Hello, I see a B using shift by dating to fashion by tating due to going to quick like a previous one, if it's right, or I can even shift by top is going to work directly for us. So that is the basic idea behind this simple CLA. So that when you do it in concert with a string, so let's try and reverse a string. So to reverse a string, just go with the reverse, then reverse Hello, a good way to reverse with reverse Hello Tula. I can also do some other stuff up or resume a string kind of to do the normal leet speak rights by the way delete l e t for leet speak is passing Hello.

They do to convert it to lit for us right very Interesting. So that's one of the biggest I've come to do with it. And kind of to check the last end for the EVO to give us some basic figures it's very interesting cipher. This is what we try to build in this tutorial. So in this session we will learn everything from scratch
