Ive got stuffs to do .... So I'll just wrap up the lecture with the terminal decoding

We can also decode with terminal too ....use Anything at your disposal, if you find it easier ....
I sometimes use python too ... Google , just anything you are comfortable with

Let's move to the terminal

I'm using termux just because it's easier to. Access at this particular moment

We need the file command installed...if you don't have it installed on your termux... Here is the command.

This is just like magic .... It tells you the file format

Like what's encoded to

See this

Let's try to decode .... First we have to know what it was encoded to right

We can use magic to check that .... Or from experience you'll know this is a base64

We won't delve into that anymore

So I put the encoded text in a file named "decode_to" ....it's just like writing to a notepad

But with command

Then I used a command called base64 on Linux to decode it

To the last part .....

So this is the WhatsApp group invite to the next group ..... If you can decode you can join .....

I'll be deleting this one soon
This time I used a password to encrypt this

oQWR95x6lKaaAqhKgBKpiz5WXgUfSTwdK4CU+Mw1j/o=

I'll solve it half way .....

First remember determine what it was encrypted to

So I'll solve this the way a normal user should approach it
...

First I tried using magic to determine what it was encrypted to no luck


I copied the hash and pasted on google ..... Got a link on stack overflow that mentioned openssl and base64

The fist letters were decoded to secret__

Okay sweet .....

So openssl ?....I had to go to my terminal to recheck myself so to be sure

So I wrote the encoded words to a file I just named " decode"

Then I used the command "file" to check what type of encryption was used on the file I saved earlier (decode)...

Then I used the command "file" to check what type of encryption was used on the file I saved earlier (decode)...

As you can see it says ....
Openssl
Encrypted
Salted with a *password*


So where is this password it mentioned


Well I dropped it earlier to be 4323 ....


In real world you might have to crack

So this is likely encrypted with AES (military encryption)
We have just 2 modes cbc and ecb ....
And it only allows 128bit, 192 bit ,256 bit

Read more about this ....
So there are limited modes to test .... A simple google search on how to decrypt with openssl and password will show you this command
