Sorry this post is a little later than i intended, i took the long way home with the whole keep fit thing but i'm home, warm and fed which is important since i forgot to take lunch today because i'm clever like that :)
Right, todays SO is on the decryption, (basic level 3 is on hold until i get a bright idea or desperate enough to google, either/or), the first level of the decryption is using ROT13.
This is quite nice for me because i've come across ROT13 before on my forensics course at uni, we were covering it for some reason that currently eludes me but anyway. The basics of this is that you take a letter, such as A and you substitute it as a letter 13 characters along, in this case N. So on and so forth :) pretty simple yes?
We kick off with this screen which contains the phrase you need to decrypt.
As you can see, there is a personalised string there that needs decrypting so for me
Now there are pretty much 2 solid ways to go about this, you can do it by hand (per se) or you can use an online ROT13 decryptor, which ever one tickles your fancy or floats your boat (thought I'd treat you to a little Yorkshire/British turn of phrase).
I'll do it by hand so we can get hang of it. We start by either counting forward or back 13 characters which takes us to b,and so on, eventually i get beth2472, what is Setec Astronomy.
I enter it and i'm right, i should be for counting back and forth (FYI, count after the letter and not including it, like numpty here :) )
Fabulous. This is ROT13 and thats all for now
Minions! i apologise for the short posts lately, as i've told you all numerous times, i've recently started my new job however it is also my first job and i'm still getting into the swing of the days and travelling home and trying to juggle stuff.
The point being that once i've adjusted, i will be back to normal :)
