To accomplish this great computational task, we need you to help out by running a special client program on your computer and allow it to connect to one of our coordinating proxy keyservers. When the client program starts for the first time it will contact a keyserver and request one or more keyblocks. When finished it will begin testing the keys looking for the one that deciphers the contest message. When all of your keyblocks have been tested the results will be transferred back to a keyserver and a new set of keyblocks will be downloaded. The amount of time it will take your computer to test all the keys in a block depends on the type and speed of the computer. Very slow systems might take as much as 12 hours per block whereas the fastest multi-CPU systems can do a block in under 3 minutes (search the Client Speed database for more information about your particular computer).
