So where is this where we're going to take a look at this tool called openness.
And this is very important for cryptography and this is mainly used for establishing the secure connection
between the sender and receiver.
And it's also helpful in generating the certificates and public and private keepsakes as well.
So it supports a lot of encryption data and we can safely and pretexting to continue to do ciphertext.
So.
We need to take both the necessary and then sorest safer comments, so this will restart the same for
comments I can execute, uh, to create the ciphertext and you can see the famous algorithms.
Yes.
Uh, this and base64, this is not an option, but we can just get the all put into this bill 64.
So now let's go and try this Bill 64, including first, let me say open sister.
So this openness will operate on Phylis, so let me try to file with the content, say hello world,
and this is our plain text message and let's.
I read this into the file complaint, so no brain file contains this horrible text.
So what we're going to do is we are going to say open and Sissel and we need to Switchfoot and Yansi.
And afterwards we will discuss further encryption algorithm that's be 64.
You need to switch for hyphen to indicate this as an option like argument and encryption base64.
And we need to switch with the input so sane and take the plain text file the display.
No, we have got this output.
This is the basis for output.
Now you can sell this with the out option out to cipher.
Now, if you take a look at this, conditions are the same for.
You will have this same ciphertext.
Now, let me go and decode this.
Oh, base64, uh, text that's open SSL and encryption matter.
I want to use this basically for what I need to specify the way that is the Modeste.
I want to know right now if I stay in and I want to listen for the input, but now I'm going to switch
the encryption with each and I would decrypt from the input cipher.
And as you can see, we got the output as well.
No, let's go ahead and try one of these.
Uh, yeah.
Yes.
Algorithm.
Let's say you want to do it with CBC.
More open.
So the issue here.
So I'm going to use this encryption method you want to deal with on the plane takes the control.
Now it's going to ask for the password.
So this is yes, we need to do the password.
Senechal and we need to interrogate.
So if you take a look at this, uh, so far, you'll get some random characters, it says it started
so random value has been added to the encryption to make sure that the decryption is somewhat difficult
for attackers.
So now what we're going to do is we are going to encrypt this whole in 64, you can pass multiple encryption.
So after this one so fast, it will take the text and it will apply the algorithm and then it will apply
the basic algorithm.
Now, if you hit enter, tell the password again at the.
So if you take a look at the server, you have this base64 and so on, you'll get this one and you need
to decrypt this user.
So this is the basic user of using the algorithm, Sylvanus.
Now let's go ahead and generate our second page.
So we run this RSA from the cryptography fundamentals and now we are going to generate the public and
the private key.
And I want to open, as I said, janoris it to join Dieser and say our protests keep.
So this KEEPON file contains both private and public and to specify the keirin letter to 048, which.
So as you can see, generating RSA, private key Pajero for a week long mudras to Prem's, so we have
already know that there will be two Pym's PNU in this area and the evalu 650 Tresa.
And remember, we are certain some basic are sensitive and we have solved it.
So if you take a look at this people and you can see there is only the private key, so by default we
cannot see the public.
We need to extract the public key from this one.
So you need to do open SSL, you need to say RSA and then Adesina to specify in the input for this Kieber
file and then you need to set up about.
So we are just extracting this from this keep it.
So this is the private key and this is the public.
So one important thing to remember is this.
Arissa is used in, as I said to his generation, and then you will see some private key that is stored
in this home for the DOD is a directory in that if you find any private key of any other user of the
router user, you can just if you have the right access, then you can just copy it into the file and
you can use that as a search command to interact with these private key without entering the password.
So that is one of these misconfiguration you see in this next section.
So we have just excited the public.
So one thing I want to show you in this kitchen is I want to say so on this text, I get the ah the
detailed information about this, uh, file.
So as you can see, there is a modulus and we have already seen this in our research and public experience.
So it is on and private explorer, which is the right B?
I think so, yes, I think so.
It should be.
And this is called a C no, I don't know.
It's just a modulus.
And after the private exponent is B and the prime, I want to be and do and this exponent one and two
and the coefficient.
So these are the parameters that are involved in Adisa and corruption and the crucial public and private
keeper.
So this is what this is.
And you can also, uh, encrypt here.
You can say and trip and you can specify that any other.
Idato.
You can, uh, even encrypt this private key to some years or this format.
So the thought about this openness and lastly, I want to show you the open SSL, so we have learned
about this 80 percent default rate so we can generate the encrypted password and we can edit that is
suitable for the possibility encryption.
And this possibility uses the best algorithm for encrypting the passwords.
I didn't know Tuesdays open as a possibility and indiscernible.
So the password, Nikil, will be encrypted.
So now you can push this in a two party preferred username, then you can put this in group.
So if you want to specify some sort for this, so it will be like only for this username and password
or to make it secure.
And you can just I have added the salt for this username and password, this encrypted possibility for
the username and password, and you can see the username here and this can be copied into the Tea Party.
When you have the right access, you can just add another user with this password hash so that what
this openness is available.
I hope you have understood.
