how about we make a deal:

i will send you a compressed 7-zip file.  in this *.7z file will be a document, and that document will contain a phrase.
i will not use anything stronger than 256 bit encryption.
if you tell me what that phrase is, i will cut you a cheque for $1000.

im not going to hold you to your 'easily crackable in one day' statement. how about a year? you can have an entire year to provide me with the phrase. if in that time you dont provide the phrase, you send me a cheque for $100.

do we have a deal?
