And Lou everybody when it comes to my advanced ethical hacking networking penetration testing goes
in this video we are going to cover the concept of steganography steganography for many report.
It's something that was coming from the older generation.
It was not something about cryptography but it was just something about hiding stuff.
But it comes back in about nineteen eighties and truly it means that so you hide something in something
away you inside Freud you encrypt it or you can touch even cheat so that all you have is secret file
or a secret text in favor of another file.
OK.
So in windows there is a common tool which names open both open book and then and then there is everyone
on code which name is openness table.
There you can try to message if I cover some fighters in how data extract data from them.
Generates was senior to embed watermark or verify your watermark verify watermark and then you will
have a very good option.
It is the face of encryption algorithm.
Then you could put your passport and then you would not confirm it in.
You're going to hide data.
But what about when the encryption phase then commission phase.
It's easy.
So in open stage in the limited session I mean in a baboon too you can have you have as an option A
E S or one hundred twenty eight and then you have a s encryption two hundred fifty six.
You have only two options.
What.
OK.
Since we are on the Mac operating system we are going to show you how it works in your life and how
you can hide it particular football if you don't want.
If you want to send a photo to the web and you want to hide your ticks inside it.
So it's a really well known tool.
It's it's a really well known tool in my wedding system that you can use it and then the name is.
I know it takes encryption.
All right.
So good defend.
OK.
Before getting into the practical part let's have a really quick view about what is exactly steganography
in what is the meaning of it what it is used for.
So how can we use it in your life.
Right.
So Steganography is the process of hiding one file in certain order.
As we said earlier you can hide it text file into a image via most popular hiding a file within a picture
if you are or are you are your phone of Mr. Wilburn you are likely already some of some somewhat familiar
with this.
Okay.
So how are you going to find a lot of information and you can even use this.
This only exists that I I'd to hide.
There is not a complete state on most clinics disclose.
Well it it is in most different policy twelve is including four are in a to meet.
So there you cannot type pseudo man and then minus is state that still hide minus are in for one provision
when I use this but when I tried to install this for us.
Oh well you can try to install it by typing sudo aptitude I find I often get installed get it installed.
OK the state does not have its ups and downs.
One upside is that it is a lot better at hiding and can easily hide any final type.
That's great.
It does so by using an advanced I'm going to hide it within the image of all you file without changing
the look.
That's perfect.
Over the file.
So this is also means that without using state or state aid or at least this Democratic code approach
as state aid it is very difficult to extract the heat and virus from the image.
Much more on this when you when you hide or when you use the still graphic for hiding these teens in
most cases just software you use for hiding the file you don't a person should use exactly the same
software sometimes if you hide it instead of hide and then meet.
I am.
I know that I am on open to stay or go Guys I'm telling you in most cases it won't work.
We have to have both side this same version decent version but the same software.
All right.
So many of you have so many comments that you can type if your own Terry not or if you are familiar
with a Jew I interpret it maybe better.
OK.
This is a very well known Web site so that you can quote more information and test the more information
you know to find out exactly what it is and how it works stuff right.
OK.
So now let's go into the main part which is the practical part.
All right.
So we have this software and then you click on it.
So by clicking on it.
So what do we want.
We want to hide it takes in into any image and send that image to a friend.
And then that will by clicking on that image he or she might think that it's just an image but the EU
as you know you wanted your text to be secret.
You said a misstep or a miss is something that you're going out finally to find out.
I use this software on that software and then that password that I've used to encrypt it.
Is this is this at the time when he download the file or your picture from Facebook or from Google form
anything and then you will not be able to see the text or while using the software that you sent earlier
to him.
So he might get disposability to read you two with your text.
OK.
So let's quote make it well here.
You have to type your password or key your password.
I can see no password.
OK I type your password I can be sure to see OK this is how it looks.
OK.
Your password are small letters.
All right.
Blowfish is a type of encryption serpent to fish.
Just go go with them guys.
They are fairly well known but us.
We use the R E S Two hundred and fifty six because its foot was not the best but E N I S T from USA
did considering it as a very well and a good encryption standard.
So many people use it.
It's so popular and it's so powerful as well for encrypting things so you can use it instead of these
older ones.
What I didn't say these are not powerful but it is I do know at 100 percent if you hide things it will
take a long long long long long long long time to the attacker to decode.
OK.
So we are not in the video of talking about it.
Now we will see it in the next video because we have it part on we should that we are going to talk
about cryptographic fees.
All right.
So we which was is and then here we want that type of message we can type blah blah blah blah or let's
go here and copy some ticks.
Let's go.
This could be corporate mistakes and then you go back and you can place in there if you want.
It doesn't matter if we get it.
All right.
So now you're going to click on input.
Why did you click on include.
It will encrypt your text and then then put the index would be here by the 8.
You can just copy the text which would be going to hear.
OK.
Which would be good to hear.
And then you can send it to a friend as a encrypting text but you might want as well to embed your texts
into any image we're going to showing you both steps.
First thing first let's check any good.
All right.
So this is the text that we get.
So you just copy eat Kobe after occupying it.
You put it here and then you can send it to your friend and then say say to him that hey I use this
software analytics intuition for privacy and this vision is a vision.
I use Android s to five six and then my password was this was this.
And then we were going to get these tics back in and what if we want to send that text in an image file.
Okay.
So we will do it OK.
So we have shown you earlier how you can just just copy the text and an encrypted and then send it to
your phone.
But what I would put the plain tags into any message so that we hide it into any image and then we send
that image to friends.
OK.
So this is the time.
Now we want to do it.
You go there and then just copy comments see or just click and click ok and copy it.
Now we're going to pass it to you.
You cannot take anything.
Oh okay.
Kill kill kill kill kill kill kill.
That's good.
Yeah.
Did you get anything.
So now we're going to be I'm going to click on input because we want to insert these states into any
image fire.
All right.
So let's go to you.
Oh so that you can see of good software within one woman.
OK.
So you can heal then you could include and make Stina the steam guy.
No ground jumping right.
Yeah.
OK we are music fans are looking to this player and then we crack open but this is the image that we
are going to include we could continue it.
It's working.
All right.
So it seems to all that this fight is in users a deep path.
My P.T. e fries strictly stick nanograms path we click.
Okay.
So now go back.
Let's go.
You.
This is my music.
We don't need it anymore.
We can go to that path.
This one.
Let's go to this one.
Okay.
This is it.
This one.
Let's go and double it.
Oh it's nice.
You always saying that inside this image.
There is a text.
No one would say that you know.
So let's let's check the size of it.
Get in for it's 1 7 9 nine eight seven right so too much.
Okay let's go back to you.
It hurts.
Oh I mean it's too easy to get in for.
You see guys some different some different.
Okay so now what are we going to do.
What are we going to do is we have to sing that fire to old friends and then so that he can get it and
use the same software as we use the same password as we used and then the A E is we're going to tell
you what why is that.
It's the same password because a guest is Sue me tweak encryption.
When are we going to get into that.
Call me when I explain you.
What is this symmetric encryption and what is the encryption key.
So what does it give you symmetric encryption.
Use the same password for encrypting for a pretty symmetric encryption.
Does it use the same password.
All right.
So this is it.
Now we can close this.
We don't use it anymore.
OK.
What are you going to do.
I'm going to try to we'll need to go through it.
We went looking at that password was nor was your password.
Let's check you sort of make it OK.
It's already.
Now we have to decode that file.
Let's say that we are not that point.
You have to click on decrypt decreed that we are going to hit me click here.
It's working.
Here we go guys.
Here we are.
Everything.
This empathic quote and this thing.
Let's say if we want to know the password Lucy was one and then we tried to put again this implied we
shouldn't at any organization it code password or anybody.
Steve Gano glad you see this is exactly how it works.
So I hope this feeling was very informative for you.
And then we are looking forward to seeing the next video.
Thank you for watching.
