# Thread: what kind of encryption is this ?

1. ## what kind of encryption is this ?

Code:
```F K L A P Q H S V
B W M C R N   F X
D T Y Z I U     E
H K O   S
L     W```
Code:
`HINT : L 2 Z 1 E 3 R 6 G 5 H`

can someone help me please ?

2. Looks like a plane old substition cypher to me.

3. Now I know that there a few guys here who love this sort of thing .................
BUT
they do need a 'little' bit of background .......

Where is it from ?
Why are you trying to 'break' it ?
is it time critical ? [a game / challenge / homework ]

can someone help me please ?
I'm sure someone can ............
you just need to start the 'help' ball rolling.

And welcome to AO

4. it`s a game and i want to learn

5. OK
It's a game ..........

Do you have a link ?
Others may want to learn too ...........

As for help ..........
I found that the book [paper + print ]
The Code Book by Simon Singh [ISBN 1-85702-889-9]

gives a good all round intro into cryptography

and at a guess I'd plump for a varient on the Vigenere cipher

6. neo-1,

You don't have to solve the whole thing, only enough of it to figure the rest out. Just like any other encryption, it can be broken with time. For this game, I would set up a “One-to-One Mapping”. Meaning either horizontally or vertically, write down all the 26 letters of the Alphabet in proper order. Then use your hint to advance each letter by the given amount. L 2, Z 1, E 3, R 6,G 5, etc. That means advance L +2 or L = N, Z +1 or Z = A, etc., places to obtain the correct letter.

A...B...C...D...E...F...G...H...I...J...K...L...M...N...O...P...Q...R...S...T...U...V...W...X...Y...Z

....................H.........L.....................N.............................X........................................A

That should get you started. In the ciphered text look for letters utilized multiply times and try find the sequence of the substitution. Sometimes that is difficult, but it is there.

cheers

7. foxyloxley
this is the game www.i-saudi.com [level8]
i think you don`t believe me ?!!!

Relyt
thanks so much for that help ..
do you mean this
Code:
```ABCDEFGHIJKLMNOPQRSTUVWXYZ
H L    N     X       A```
what about H ??
L2Z1E3R6G5(H)
what should i do with it ??

and i cann`t understand what is the relation between the cipher text and the hint ??

8. about the way ,, someone tell me this encryption is in the system : [Enigma / the nazi] ..
so can i get now more help on how to decipher it ?!!!

9. NEO-1,

Well I really doubt if we could get a WWII German Enigma Machine on Ebay, however, I have toyed with simulators from this site you might give them a whirl. I'll go to the game site and see what's up.

You can get copies of the Banbury sheets with explanations on how to use them. Just google them.

cheers

10. Banbury Sheets cann`t fixed the problem !!
i`ll try to find something else
