Cryptogram Puzzles

[Light]

I've seen the many riddles here and was thinking, if there are people here, that are interested in solving cryptograms.

A few rules first!
1. If you post a cryptogram here, you should tell the method you have used or at least give a hint.
2. You can encrypt a message multiple times, but tell the people here that you have done it and test it afterwards so that it's still possible to decipher.
3. DON'T use programs to work it out, that's just not fun!

If you want, you can even encrypt lateral thinking puzzles, were you must first crack the code to solve it.

Let's start with a simple Caesar cipher:

EQPITCVWNCVKQPU! AQW IGV C EQQMKG.

[Sayumi]

Got it!!!

Spoiler:

2letters backwards, so:
EQPITCVWNCVKQPU! AQW IGV C EQQMKG. becomes:
CONGRATULATIONS!   YOU GET A  COOKIE. *yay-where is it???*

lets see...
my hint is

Spoiler:

CHEMISTRY!

NPPBe NePHe! CaOFK FK HVBKPAlB  ! MnPScAr CaScArSi SiPV...

it sort of needs two steps... but it's not really hard.

EDIT: Crap-I missed a letter! It's HVBKPAlB, not HVBKAlB. Changed now

[bash7353]

Hey,

I don't really know how this works; I understood the first riddle but now I also see capital letters and lower case letters. I don't know what to do or to think. Can someone give me a little heads-up.
@Sayumi: A PN in German would be appreciated.

Later.

NPPBe NePHe! CaOFK FK HVBKAlB  :D! MnPScAr CaScArSi SiPV...

Spoiler:

Copy and paste from my Notepad to show I did it by hand Everything was lined up in there but it got shifted due to font. Letters get turned into numbers using the periodic table and those numbers are turned into letters by what they are in the alphabet.

N P P Be Ne P He ! Ca O F K F K H V B K Al B ! Mn P Sc Ar Ca Sc Ar Si Si P V ...
7 15 15 4 10 15 2 ! 20 8 9 19 9 19 1 23 5 19 13 5 ! 25 15 21 18 20 21 18 14 14 15 23 
G O O D J O B ! T H I S I S A W E S M E ! Y O U R T U R N N O W ...
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
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

So that would make it "Good Job! This is Awesme ! Your turn now..."

So here is mine:
10110010100111101000011010011101100110101101111110001011100101111001011010001100110
11111100010001001111010001100110111111000101110010000100100001101111110011010100111
101000110010000110

Notes:
1. That is supposed to be one long string of numbers, not three lines. I had to separate it as such so it posted right.

2. You are allowed the use of a binary converter such as http://www.nickciske.com/tools/binary.php for this code only.

3. No it is not supposed to make sense if you decode it from binary as is.

4. I don't think I'll have to but I'll give a hint if its needed.

Spoiler:

ASCII 8-bit letter values start with 0! so switch all the 1's with 0's and vice versa in 10110010100111101000011010011101100110101101111110001011100101111001011010001100110
11111100010001001111010001100110111111000101110010000100100001101111110011010100111
101000110010000110 and you get "Maybe this was too easy"

Here's mine
HPQUED EVC OSRGDSS YK GNN
(edited. Thanks ayw!)

Clues:
-It's not a one-to-one replacement
-The substitution pattern changes as you progress from left to right (but in a solvable way)

Extra hint if you need it:

Spoiler:

The first letter is "h"

[ayw]

@tera, There is a mistake at the fourth letter that carries over to the next three letters. After the eigth letter the code is correct again.
The code should read HPQUED EVC OSRGDSS YK GNN

Spoiler:

From the given letter move shift backwards by 0,1,2,3,4,... . The following loop helps do it easier when numbers become large.

A  B  C  D  E  F  G  H  I  J  K  L
Z                                M
Y  X  W  V  U  T  S  R  Q  P  O  N
The part in the brackets is where the mistake slipped in.
code:  H  P  Q [T  D  C    D] V  C    O  S  R  G  D  S  S    Y  K  G  N  N
shifts: 0  1  2 [2  3  4    5] 7  8    9 10 11 12 13 14 15  16 17  18 19 20
result: H  O  O [R  A  Y    Y] O  U    F  I  G  U  R  E  D    I  T  O  U  T

Here's the next one:

EGRM, IHJ XNM SIZ SABB GFMH

My hint is...

[tera]

>> ACK thanks a lot ayw, props for figuring it out despite the error... corrected it now

[dany]

I think I solved the EGRM, IHJ XNM SIZ SABB GFMH code but since I'm not a native english speaker I'm not sure of the answer

Spoiler:

First we have to put the letter like this:
A B C D E
P Q R S F
O X Y T G
N W V U H
M L K J I

Then it's about symmetry, axial symmetry (horizontal and vertical) but also central symmetry, for example the A can become E (horizontal), M (vertical) or I (central). The problem is I didn't find a way to know which symmetry we have to choose for each letter but I can obtain something like this:

"Move, and the waz will open."

Don't know really about the waz but it seems it's an english word I didn't know (Wikipedia) and I'm not sure about this word since there is no Z in the letter grid and I don't know what to do.

Here's my puzzle:
PJYNM GRWY

Hint :

Spoiler:

The key is a mathematic symbol

Hint 2 :

Spoiler:

I also used a basic and easy way of encrypting a message 

[ayw]

@dany, Pair Y with the one letter that is missing

[dany]

Yeah thank you, it clearly makes more sense now. I was too focused on an English expression I wouldn't have know.
And thank you because I really took pleasure in solving this.

While the Cryptogram has remained popular, over time other puzzles similar to it have emerged. One of these is the Cryptoquote, which is a famous quote encrypted in the same way as a Cryptogram. Another is the Cryptoquiz. This puzzle starts off at the top with a category (unencrypted). For example, "Flowers" might be used. Below this is a list of encrypted words which are related to the stated category. The person must then solve for the entire list to finish the puzzle.

from http://en.wikipedia.org/wiki/Cryptogram

any got some of these kind . I lov figuring out the longer ones

Later very simple code for you use what is above and start at h

.    8) 

[ayw]

@sstimson Thanks for the info. Yes, a cryptogram needn't have a mapping according to some pattern. You can just have a random one-to-one mapping of characters like your example, which could read

Spoiler:

.     >:( 8)   :-X
H  i  .   I    l  i  k  e     t  h  i  s

though this is not a unique solution because the example is short.  You're right, longer cryptograms are fun since they contain more 'frequency' clues. Our examples so far make up for it by having some cyphering mechanism that can be deduced from logical or lateral thinking. 

@next person, dany's cryptogram has yet to be solved.

This is a guess ( logical guess based on your clues and word length )

Spoiler:

Does PJYNM=EQUAL & Does GRWY=SIGN?

[dany]

That's not the right answer, I think it will be easier and more exact if the first hint is :

Spoiler:

The key is a mathematical constant

And here a third hint :

Spoiler:

The last letter is a S
