my friend gave me a challenge 3 days ago, that i am sad to say, i have no idea how to fix it. haha
anyway, he encoded a text document with a 2mb encryption of something. he wont tell me.
is there anyone who could help me decrypt this document?
i put it in a .zip.
please go here for a list of my instant messaging programs you can reach me at. ill continue to check this thread, but many a time i forget.

This website will be your newest friend. ;)

ok thats a pretty neat site, and i will definitely use it in the future, but as for now, that does me no good.
any other advice fellas?
bumppp!!!
Um Accounts.txt - maybe it should stay encrypted..
I think that it will :DQuote:

That sounds like 2048 bit encryption to me? (256 x 8) AFAIK that is considered unbreakable with current technology?Quote:

If thats is the case it is a public/private key kind of setup and yes its near impossible to crack if it is encrypted with a good password.
I think its time for you to ask your buddy for a hint ;)
I looked at the txt file, and it seems there is a lot of repeating of several didget numbers, so it could be a possiblity of substitution of multiple characters for one. that 2mb encryption may be bull..
Hmmm,
All lines have a leading zero, so that is probably irrelevant? 5189 looks like punctuation or a space?
It is a song, hymn, prayer or poem ;)
Just curious but why would your friend give you a challenge to decrypt something if you have no idea on encryption? If he wanted you to learn then he would teach you ;)
Anyways, on to the subject.
Yeah it doesnt look like this is really 2048 encryption. Just too many repititions. There are 24 occurrences of '078695101' all at the beginning of each of the 24 lines found. Similar goes for pretty much any grouping of digits.
You might want to ask your friend some more info.
Me thinks Nihil might be on to something :)
All lines also end with 9 or zero---also, there are several sequences that repeat.
11213001213110, 0102715, etc.
It is no standard encryption---no special characters or letters. Even simple reversible Cisco level 7 passwords have letters in them. I would guess that all numbers or sequences of numbers correspond to letters. To separate them, he probably uses zero or one, to indicate the beginning, end, or separators.
This is important, because for example---several instances of 112, and a few of 1112---but why not 1112? Because the first one can be assumed that it is the last number of the previous sequence. This indicates that perhaps the code is three digit numbers, each corresponding to one single letter. Or...any number that is higher than 6 does not belong to a pair of numbers---take them all out of the equation, and what is left? Just thinking out loud. The ones and nines that each sequence begins and/or ends with is throwing me...but this seems to be his own code---a bunch of repeating sequences, all sequences begin with 0 and end with 9 or 0, and no letters or special characters.
