Encryption challenge
No reason - just checking :-) - it's the first time I've posted one. Not sure what clues might be required so if anyone is interested I'll happy post some!
Here's the ciphertext
<<BEGINS>>
„½»cX€CÞî±,¡oîl„@O¡,€ËÞW€[“•€m•¹½™›toæV7q€aÈ@I —ou“€toæg«Êæ ¹ȕòÊ7 %rF Õs•£CÊk@›½@thÂt¡ea³Êæ'æ@ga«±G@æhÞ«ÆÈ€“aÆ[â
<<ENDS>>

<<ENDS>>
BTW ignore the line break after the %rF - it's where the text editor wrapped the line
It appears that the copying and pasting corrupts the text (charsets I guess) - how can I put a copy of the ciphertext file up?
A decent filehosting site:

As for clues... does the encryption use a password?

Thanks Catfish666 - I had a googledrive account... you'll need to download the file rather than view and copy/paste I have tried that and it decrypts ok - sorry for the hassle

The encryption uses :
the initial seed (dp)
the initial number of iterations (int)
a constant (dp)
and an algorithm for generating a key
My interest in this is twofold - one is the possibility of determining convergence on the key generation and the other is the possibility of determining if the set of functions which are termed chaotic is an infinite set...
I think this is effectively a modified onetime pad and suffers from key distribution problems (obviously) but it provides, I *think* :-), a mechanism for a multivariate key (the locked box has - effectively four locks - the seed, the number of iterations, the constant and the algorithm itself.
Let me know if you want anything else?
