This is a competition to solve the most codes developed by your fellow members. I will start with one code, and anyone can feel free to add their own. Please make them semi-difficult. Challenging, but not impossible. Please do not make any extremely simplistic codes. Only codes on this post are part of the competition. I'll keep track of how many codes each member has solved.
Here's the first one:

Code #1
Creator: Eagleye
ocws ny imbd

Code #2
Creator: Eagleye
zpv ibwf xpo

Code #3
Creator: 7.62 Nato
o zdv eruq lq d eduq


Code's solved:
Nato: 2
Code's submitted:
Nato: 1

zpv ibwf xpo

you have won

WOOT I WIN

[eagleye]

good job nato, now try the hard one

[7.62 nato]

o zdv eruq lq d eduq

Solve that ######! lol

Good luck you guys, you are gonna need it

[7.62 nato]

NATO IS BEST


GAH

[T.E.N.N.I.S]

umm how do you make codes?

[hnQ]

codes should have a way to figure it out right? not just random letters to form a phrase rite?

[anthony]

Yeah that's going be hard it could be any combination of words with those letters maybe some hints XD ^^

[eagleye]

talk to nato he figured 2 out.

[7.62 nato]

*sigh*
zpv ibwf xpo
And for the math function you subtract 1 meaning z=26-1=25, and 25=y

So p=o and v=u
Then just solve all of them like that.
So you convert the letters into a number and then apply a mathmatical function

you have won


it's easy... lol

yah i'm sorry, you have to have an intelligence quotient over 65 for this game....my fault.

nah.. but its too difficult for me (im 11)

Comon blacky, i think that for start you can solve this:

the problem is i understand hlaf of what there is standing there xD

EDIT: found out

umm WTF?
lol not right.....

k i think i need help with this -.-

o zdv eruq lq d eduq = n ycu dcqp kp c dcqp

i know it doesn't but wth?

[tyler2k7]

ooh ive got one

4.5 6 7.5 11 2.5 6.5 12.5 10 2.5 0.5 6.5 6.5 0.5 10 2.5 7 10.5 5.5 2.5



AHAHA NUMBERS WOO WOO!!!

Best of luck to all

[7.62 nato]

Ok, i dont think anyone else can even play this game.... and tyler that isn't how it works.....

and snowman, that is sooo far off

[T.E.N.N.I.S]

hyrsy tryed to learn me.. but to difficult xD

Codes can be based on other things then turning words into numbers and applying a mathematical function!


I doubt anyone here would ever crack this...

[7.62 nato]

got me...

[hnQ]

I bet I could find a code no one would ever solve it

[tyler2k7]

omg alex!!!



and nato, mine was easy...double each number and find the corrosponding letter on an a=1 b=2 basis

Of course >.< Thats the whole point of codes!
Well you can bet someone would solve it eventually.

Think about it, if people could crack RSA based encryption, or similar, you wouldn't be able to buy stuff on the internet.

A lot of the current encryption schemes are based on semi-primes, a number that has exactly two prime factors, and IIRC there is a $1million for finding a pattern in the semi-primes and their factors.

Luckily, the large semi-primes are nearly impossible to factor so our internet banking is safe for now

Unfortunately, with quantum computing will come the possibility of breaking codes




Try and factorise this 617 digit bad boy :

[hnQ]

I wonder how can ppl break others codes

[tyler2k7]

oh my GOD did you come up with that just now?! 8-)

ea5c82c0eab14bd191213656f06e0cb3d9c66097

Needs to be geek in maths to crach THAT

Looks like computer codes, well, string lenght redirects to SHA1 on me...

Try cracking this one:
