stop re-posting - what was wrong with the entry below ? Ha lee wrote: what's the use of uploading the english dictionary in our program? possibly so you can count the frequency of letters which may help you figure out the secret key - except, as you state, the text is in Italian .. so Im not sure what good an English dictionary would be. Maybe, Commonest English Words -> Letter Frequencies has some mapping to Italian, but even with my limited Italian, it doesnt gell .. Maybe Carlo (Pallini) if he's watching may have a comment on that Either way, please be patient when you're posting questions - dont repost becuase you dont get a reply in 5 minutes - most of us here have jobs to hold down !!

yes, but i POSTED IT HERE. So if to seek help from any of the Java programmers who has already worked on this encryption decryption program or related to that one.

Look into some kind of character frequency analysis (works for simple encryption schemes). That might cut down the computational complexity a bit. And no, I'm not going to tell you how to do it, since it's a homework. ;) home

ETOALIN.... The encryption algorithm is very weak, and you are expected to attack it using letter-frequency analysis. For example, in an substitution cipher for english the most common letter would correspond to E. I'd assume that they have given you an Italian dictionary text file to use. I guess they want you to try with the English dictionary to see it not work (or maybe work), so you can discuss it.

If fly and you are 2 different persons then why are you both writing me the same things??? Only you and him have really got some problem but all others don't have any problem with me . If many people have voted 1 for my comments , you also got the same . Don't make it your misconception. You are of worst standard for me. And go to hell, I didn't come to you to beg for anything. If you want to answer well and good, I would be obliged as this forum is to help others but if you don't want to help me, I don't care . But at least stop being rude to others and don't stuff your head in the things that you don't understand because that will make you frustrated for your low knowledge and you would be nothing but only rude to the people. Understand?????
