RC5Crack/HelpNotes
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

OK, RC5 is a public key encryption technique being pushed (amongst others)
by a company called RSA Inc. Their latest offering is a 64-bit key (ie a
pair of 64-bit prime numbers), and they are offering a prize of $10,000
dollars to anyone who can crack decode a test message encrypted with this
technique.
One way to solve such a problem is called the Bovine algorithm, which is
basically an exhaustive search of the key space (~2^63 keys). This, not
surprisingly, takes a long time 8-).[1]
distributed.net are using the Bovine algorithm and achieving the necessary
computational power by providing client applications that sit on your
machine trying out keys in any idle time the machine happens to have.
To set it up is very straightforward - download your client (go to
http://www.distributed.net/rc5 and follow the link to the cient download
page). You need to spend a few minutes configuring it - a "standard"
UK-based home machine work need to be set up something like:
User: Your email address
Firewall: No special encoding
Preferred keyserver: euro.v27.distributed.net
Connection mode: Offline always
Blocks to buffer: 10 (the default is quite reasonable)
Checkppoint files Ticked (the default name is usually sensible)
Enable E-Mail log: I haven't bothered.
Logging: Moo for each block completion
Log to file: Ticked
Performance: The default seems OK
Autolaunch client: Ticked
Run hidden: Not ticked
All this is covered in a StrongHelp manual, and !Help messages are also
provided.
Having configured the client, you tell it to connect to the distributed.net
keyserver, and it downloads a number of blocks (by default, a block is 2^30
keys) and starts trying them out. At your convenience, you connect back to
the keyserver, and the client uploads any completed blocks and downloads
more. About a day after you upload your first solved block(s), your get an
email welcoming you to distributed.net and gives you a password. Once you
have the password, you can connect to distributed.net, perform an "Email
search" on your email address, and you can join a team (eg the Acorn Users
Group teamis team #4266).
If distributed.net are successful and get the $10,000, it is split as:
$1,000 to the person who cracked it
$1,000 to the team the person belongs to
$6,000 to a charity decided by vote of the participants
$2,000 to distributed.net (for providing the infrastructure, etc)
Realistically, you don't have much of a chance of winning any money - but
distributed.net provide some quite interesting statistics on their pages,
and the more people who provide solved blocks, the better Acorn machines
look (when I looked this morning, the Acorn Users Group is about 2100th out
of anout 4,000 teams - the aim is get AUG into the top thousand).
distributed.net also maintain stats on individual keysolvers (there are
something around 70,000 people who are part of "the fasted computer on
Earth") and individual architectures (ie x86, ARM, PowerPC etc) so it makes
quite interesting reading at times.
The Acorn client is very well behaved (apart from the cow on the iconbar,
you wouldn't realise its there), and on my RPCSA I get about 110,000
keys/sec if I run it in the desktop, and about double that outside the
desktop (which means outside the desktop a single 2^30 block takes about 1
1/2 hours).
> Does it make toast?
No, but the cow does moo when it completes a block - is that good enough?
[1] I assume it's called the Bovine algorithm 'cos it's slow and stupid.
