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?????

I do posted into several forums and perhaps in the wrong ones too. But for your information, I got better and more useful replies from other forums than this one. Here too, people have been helpful except the fact that I cross posted my question several times, which was by mistake and I realized that later. Yes it is my assignment and you are again rude when you say that people are blunt and I fell in this category. But I had to post my assignment here because I don't have any idea about cryptography and I am new in that field . But as far as programming is concerned , I don't have any problem. That's why I just wanted a clue which algo may work or what approach should I use. And for your info , I got very positive replies from everywhere and every person except when I had to confront an immature person like you who can only make useless debates in order to show the world that you are the only genius in the world and all other are just stupid. I have never ever been lazy for my assignments. this was my first ever post here as i told you I don't know about cryptography and just know about programming. I didn't get any hostility only you are a strange kind of person , who made me to think more about the offensive talk rather than my assignment. In the end, I would say 'can you tell me how can I get rid of you?'. Because I have some other stuff to do too . I am not free like you to quarrel with different persons on the web. I had heard that programmers don't even get time to eat . But I dunno who are you really. So if you have got nothing to do, at least stop arguing here. Because all the world is not like you. Find a free person like you who can also argue in this way and then start arguing with him. i am not here to entertain you when you have nothing to do. Stop here.

And moreover, if you think I have been rude. I really apologize for that as I am a responsible and a mature person.

actually, it wasn't a lame come back. something must have hit your a** that's why you have been so rude. And i misspelled your name because I don't remember as it is changed every time. It seems to me that there's only one person in the room with some problem who sends me messages with different names, sometimes with crab, fly etc. If you are really not interested in answering people about their problems related with programming field. don't let them know that you haven't got any maturity. I used to have a good view about the people of the UK when I visited England last year, but you are the one has started changing my view about them. I would just end up everything here saying 'shame on you . be mature now'.

No, it has already hit your ass. I am Sorry for you Mr Crab. ooo I mean. whateva.

Well and if you are not capable for helping anyone, stop being rude and stay at home . such a looser. everyone has self respect, but if you don't have any. I can't help. I just asked for the help not for your rude comments which really represents your manners too. got any education??? so far you didn't tell me anything related to my problem but just that rubbish only. If I post a question here, it means, help me if you can. But if you can't don't simply get rude. And now I know how much capabilities you have got. I don't know what you are doing at that site. No more offense, i say. If you don't wanna help, I am not asking you for it from you. Bye!!!!

quite helpful it is Dave. yeah the blank is represented by w as I have figured it out. so between two w there is a word. And accept my apology, actually the project is same but in 2 languages. so I have to upload an English dictionary if the text is in English and Italian dictionary if the text is in Italian. But I mixed up 2 different things. So how can I proceed with that?? should I use all the permutations on each word separately??? How can Caesar cipher be helpful in that case? Actually I am a C programmer but don't know much about cryptography, that's why I am seeking help here. I would be thankful to you if you explain me things how to do it in a simple and detailed way. Thank you Dave. HA Lee

Why are you offended Mr Craig?. I didn't write that sentence for you. I dunno why you answer me like that???

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.

If you are moronic and can't answer that. stop being rude anymore. and do some other stuff please. By the way, I am not Mr. I am Miss Lee ha. ok???

what kind of humiliating reply this is Mr fly 904????

well I have been working on an assigment and it states:: A program has to be developed, and coded in C language, to decipher a document written in Italian that is encoded using a secret key. The secret key is obtained as random permutation of all the uppercase letters, lowercase letters, numbers and blank space. As an example, let us consider the following two strings: Plain: “ABCDEFGHIJKLMNOPQRSTUVXWYZabcdefghijklmnopqrstuvwxyz0123456789 ” Code: “BZJ9y0KePWopxYkQlRjhzsaNTFAtM7H6S24fC5mcIgXbnLOq8Uid 3EDv1ruVGw” The secret key modifies only letters, numbers, and spaces of the original document, while the remaining characters are left unchanged. The document is stored in a text file whose length is unknown. The program has to read the document, find the secret key (which by definition is unknown; the above table is just an example and it is not the key used for preparing the sample files available on the web course) using a suitable decoding algorithm, and write the decoded document to a new text file. And I know that I have to upload an English dictionary into the program but I don't why it has been asked.(may be not in that statement but I have to dO THAT). My question is , while I can do that program using simple encryption/decryption algorithm then what's the use of uploading the english dictionary in our program? So is there any decryption algorithm that uses a dictionary to decrypt an encrypted file? or can somebody tell me what approach or algorithm should I use to solve that problem??? An early reply (and also authentic one) will be highly appreciated from you. Thank you guys.
