Hi. 1st posting here. Just browsing to see what Perplexcity is all about while waiting for my first packs to turn up in the post.

This may not be relevant but if you google "69 A9 3A FD C5 AD 43 8F 48 53 56 0F" being the first part of the hex code, one of the hits is for

http://minnow.cc.gatech.edu/squeak/2969.edit

which is identical to the above code except that it stops short of the last 59 characters.

This seems to be an incredible coincidence if this puzzle is a 64bit encrypted code?

Just a thought..

I don't know anything about squeak or how to feed this code into it or what might come out the other end, or alternatively what was put in to squeak to generate this output.

Hope this helps.

Hmm maybe not.

Looks as though someone has inadvertently updated a web site while trying to decipher the code

Apologies for the waste of space...

This may be a stupid question but does anyone know what form the they expect the answer in to solve the card?

It might somehow bring us closer to the answer...

Has anyone created the project on Sourceforge yet? This was mentioned a few weeks ago, but it doesn't appear that it has been started yet.

Hey there, (1st post )

Well I haven't had time to read through all the posts yet on this thread but I was wondering has anyone found any relivance in the 5 cows at the bottom?

I was possibly thinking this was a hint at the password. Could it be "Five Cows", "5 Cows" or maybe even in spanish "cinco vacas".

Hi guys. I'm still looking for a bit of guidence on how to use rccrypt. I am running it from C:\RCCRYPT and am using the following command;

rccrypt fivecows -a

when this is entered, I get the following message displayed on screen;

Starting with key 534341524C455454, attempting 0 keys

After that nothing happens. With my very limited knowledge, I was expecting some kind of output file to be produced, which I could then compare to the card - Yes / No?

What am I doing wrong here? any help will be greatly appreciated.

Thanks for your time.

Right well I know that certain types of encrption can 'leak' information in the IV specifically WEP, although lots of these packets are need to break it generally. Although some form of old encyption can be statistically hacked one that comes to mind is the vigenere cypher. Now is it possible to do a statistical hack on this? Have you tried putting this through other breakable cyphers?

A statistical hack is worth a go I feel.

Hey HiveMind, if you go waay back to the first few pages, it was determined that this message is encrypted with RC5-64. Also, the hint from Von's text line was the name of the RC-Crypt program, which encrypts and decrypts RC5-64 messages.

I'm not quite sure what you mean with 'statistical hack' but if you mean brute force then that's what I'm currently planning.

Should we make a wiki page where people can post which keys they have tried?

Hi Again - Richard from RC-Crypt here again.

I've contacted the nice people behind Perplexcity (as they are using my code), and I don't think I'm giving anything away by saying that they did use rccrypt in an unmodified form to encrypt something.

Needless to say, there were no clues on how to determine the key, or what you can expect once it's decrypted.

I've checked the (v1.6 *nix) code and can't find a bug when getting the key from a file (see earlier post from Ashin, p13).
Ashin, if you read this, can you please let me know which version(s) you were using, how you determined the bug and what fix you applied?

If there is a bug and I missed it, I want to fix it for the next release of the code. (I will also give credit on the web site and code history to you...)

Thanks,

Richard.
