Challenge #4 (experts..) HARD

[WaR_MaN3]

Hello,
I didn't mean like it was totally random but i'll list all the ones I did:

First one: 31E000201437
I think the first 3 were random...

Others:
 = abc

)*+ = xyz

#Ð*Ð Ð!$ÑÑÑ
Above One = crack my code please!!!

%$Ð$ÐÐ&#ÞÞÞ*
Above One = this is a number...maybe

Ð%Ð* &Ð&*$Ð(Ð'#Ð#Ð%$
Above One = i bet you guys will never crack this

Also, what do you mean my code isn't that great? I don't understand...What did you do to try to get the random thing you came up with? Also, I'll post one below, another sample and use ANY program out there to decrypt it...To me the code looks pretty unbreakable...but.

Sample:
*Ð

But see now you will know...because looking at the above code you know that the Ð is a space.

Another thing. How more complex is it with other pro? Can you send me an example? And I think you guys said that if I want to learn encrpytion go with XOR or whatever. Why? I downloaded some code and it isn't that great...If I really want to mess up my encryption and make it basicly uncrackable...Well first of all I enter a source code, so If i say hey, for instance I could enter "h" for source code 36 or something, "e" for 98, and "y" for 120 And that would be uncrackable pratically. And do decrypt another person has the program and you would just go on a pattern... 36, 98, 120, 36, 98, 120...

Thanks,
