Cryptography
In Cryptography teasers, a phrase or expressions has been encoded in some way (frequently by replacing letters with other letters). You need to figure out the encoding method and then decode the message to find the answer.Cryptography
Andrew Richardson, deputy head cryptographer at a top department of defence (DOD) facility, was working late one night. The last set of codes he received to decipher came from NASA 's space station. Apparently they had been receiving the same 5 set of codes over the past week on a high frequency band in visual digital format. They read...............
wmoa eemn cfuu orrs
wkia eesn ltpe ihlt
hwth oeno pgem eewe
wsta auob rnpl ispe
aust lmmd laui hnse
"Strange," Andy thought. "Never received work from this site before."
Eager to finish and get home, he set to work on figuring out the troublesome codes. The first one took him some time .............
WE COME FROM URANUS.
"What!" he laughed. He thought it was a joke or that he had deciphered incorrectly. However he continued using the same template, and by the time he'd finished he wasn't laughing anymore. He quickly picked up his phone and dialed his director and then the head of the DOD. Somehow he knew he wasn't going home tonight.
What did Andy find that got him so worried?

Hint
Julius Caesar used to write codes this way. Realize that all the strings of text have 16 lettersAnswer
All the codes can be broken by arranging the 16 letters in a grid of 4*4 from left to right. The result is a phrase readable via the columns starting at the top left corner, reading down and ending at the bottom right cornerUsing the first code
wmoa eemn cfuu orrs
W M O A
E E M N
C F U U
O R R S
You should be able to read ........
WE COME FROM URANUS.
The other codes read:
WE LIKE THIS PLANET.
HOPE WE GET NEW HOME.
WAR IS UNSTOPPABLE.
ALL HUMANS MUST DIE.

it was freaky. but not too hard, and interesting.
scary.
oauo kmpt bmst eecy
Loved it!! I got it on the first try
LoveGizzers comment! I like the teaser. This one took me a minute but then again I am not the best at these ones
when I was editing this one I never expected it to be approved
when I was editing this one I never expected it to be approved
didnt get it at first but when i did it scared me!!! ,by the way i didnt get Gizzer's comment
kool , i dint get it at first but still its cool.
One of the best story lines in cryptography I know, extremely well done! And to continue in gizzer's spirit, I can only say msai_amvt_kyoe_efrs!!!
The teaser is easy, but it is fun too. this is one of my favorites.
I didn't get gizzers comments
Ok beamm up scotty, or something like that
tire hsta isos sofy
I cant belive this got approved its cruel
dude, this is absolutely cruel. ur hint isnt even correct. ceasar's coding method was a shift of the alphabet, lining up 2 alphabets, and shifting the bottom one x number of times.
for example, a shift where x=1
abcd.........xyz
zabc.........wxy
this is the only coding ceasar used. it is an inteligant method, and i must say, ur 4x4 grid was a good technique, but the hint should b changed or taken off. i got it by observating. c, i tried shifts, but i realised w to w could not give e to u. impossible. but then i looked at the alignment and realised a dif pattern, which gives u the 4x4 grid, w/o drawing one.
simply write the letters in order by the first of each 4 letter segment, then second, then third then fourth in each line, and u get words from it.

Its my first guess, and it was fun!

Awesome teaser! i thought it was quite clever hahaha
If you didnt get Grizzers comment you need to go and watch star trek. Now.

I'm sure the message meant to say "We come from ur anus" - and they thought the attack was coming from the stars
Got it without the hint.
This is great and all... but it always baffled me how "Aliens" know English.
This teaser gave me goosebumps
this scared me! Excellent teaser though. Well done.
Great teaser! eek!
Had to look at the hint, but it wasn't so hard after
