Hello guys,

I know its been a while I last posted.
Here's the 6th challenge of HTS.

"Network Security Sam has encrypted his password. The encryption system is publically available and can be accessed with this form:"

We are provided with the encryption method but not directly. We can find out how the encryption algorithm works by entering any normal text and it will give us the encrypted text.

I tried with with "abcdefghijklmnopqrstuvwxyz"  but unfortunately I don't know why, it din't turned out to be anything. I immediately came to know that it does not accept very long passwords.

However, I wanted to test the encryption algorithm, so I kept my try going on and found that it accepted "abcdefghijkl".

Finally I entered "abcdefgh" and I got encrypted text as "acegikmo"

The below pic will explain the scenario more clearly.

I hope this would be readable.
So here in middle was the logic.
Every letter was incremented from zero to 1 to 2 and so on.

Now I just took the password provided by hackthissite and applied reverse logic to the encrypted password.

Due to the presence of symbols in the password, I took help of ASCII table and applied the logic.

Next pic shows the logic and how I got the password.

Thank you.

I will post next solutions soon. :-)
