    1.) Write a cipher which you invented or is already commonly used.
    (Use a cipher which doesn't require a codeword so it may be solved by
    us.)

    [and/or]

    2.) Solve the ciphers we have written.

    [and/or]

    3.) Explain your cipher when attempts to solve have been exhausted.

    Attempting to get this thread going is futile. What will people post, ROT13 ciphers? Fairground ciphers? Come on. Besides, there are no good encryption methods that do not require a key.

    ROT13 ciphers?!?! Is there more than 1?

    Lets presume the Original Poster intended simple substitution cyphers to be cracked by analysis and logic. (ie look for single letters;a or I common combinations; the, and)

    These do not need a 'key'to crack .... just time on your hands.

    That is what I meant.

    There are all sorts of difficulty levels. Substitution or the use of keys or whatever you can think of will work.

    This is easy: sfeipuqbxo = 17-5-4-8-15-20-16-1-23-14 = redhotpawn

    Why don't we all use our imaginations a little bit?

    I've already written one which is quite simple.

    As wolfgang59 has stated, a bit of logical analysis paired with time will make many invented cipher's both possible and entertaining to solve.
