Decryption challenge... I've got a very simple encryption algorithm, and I was wondering if anyone would be willing to take me up on an offer to prove that this algorithm has certain qualities. My goal is to prove that it is secure, in that the average I.T. person or computer programmer isn't going to be able to look at the cyphertext and say "Gee, I bet this says 'Hello World'". Secondly, since I don't have need for super-strong encryption, but I do have need for very, very, very light-weight encryption that this text would take at least a couple of hours and a reasonable knowledge of encryption/decription methods to get at the data inside. My challenge is this: I will post the sreen name of the first person to correctly decode the following cypher text. If you are interested in trying, knowing what I've stated above, reply to this post so I know there are people banging on it. Bragging rights to the first person to break it open and reveal the message inside. In case there are newlines in the message that you get, note that there are no newlines. This should be one continuous string before attempting to decode. Thanks, and good luck. --Sim. --- MESSAGE --- pFbeEQUsCmhqGHRexPwNJweDkrvJ/yx+LrnHv +Eza3XJYqsL0yCLftftYsHERYlxi6XkKL5fjWOl0BBNgTqXYIcAtnp7Qxs2ODlvTMT8CWkf19qH1eA6MS +Llaf9Llky0GqvAt0njXfX5XiFkFCHeMfx5m36ToZjucVEBuRZyy7UftIUVjBFajgEc17E8Eh3FJjVmsH/ aXAuiZqx4HtYd9JmsAaRY5R2mPxgwMRFgz2E9/wj/ UPFZajHX0yOO9l3m0nIGRQlTz93AXRSi/8bOEaYwMjX8zoxKZmVsfAtQn3RcOIGkyfEdpb/ dYWCXp49iOvsbe5Ol2Kv2xBNhnOKaJhM3k97Qxk2OCZoWpCxAXRGg9qNgOEqYyWI2/78OkZ3hHqtEt00hX2DrGHAxEWDPYX36Cq +Sod +tcEPGeRZ9A2jUt4eVjBFajgGclKQ9EhqA9uSmMz3KGIlzcWr5nsJW4N1p0eZJodhjvx4wIARlXKS96k961GffaWXEFCHc41vkRrIBRQjT3xsUWxSivRIdAnX +8jL/CZmYITB+eF7RX3QI7EXnC7KM/qGAa+tFoBxx/ XmPuoLnH61xxBJmzqDYtRX3gMFKE16ODBTerS/ SFMOltyD07IodiGE2/70NFky0GKpDpMkxGef5X +Fh1mNcYvg5yr7B8VwrtEQWoY9nnWVTs4cFz1DcHYCIFSKsRtoCoHbhseyIGVu4L/ TmHYGQc1u7Gf9Q+QT94wMpeQx7B3nhYlNnivlEcC1MDnpU/kH --- END MESSAGE --- |

Sebastian is correct, if you want us to 'prove the algorithm has certain qualities' then you need to provide the algorithm. The text arrived, not on one line, but randomly truncated. I'm guessing the truncation occoured at points where there were spaces. So, with no algorithm, and probably corrupted ciphertext, you've asked us to perform close to the impossible. However, this does not mean your algorithm is any good. Bogwitch. |

Do your own homework. You (or your parents or taxpayers) paid for the class so to try to get something out it. |
