Here are some examples:. CyberChef can handle files up to around 2GB depending on your browserhowever some of the operations may take a very long time to run over this much data. If the output is larger than a certain threshold default 1MiBit will be presented to you as a file available for download. Slices of the file can be viewed in the output if you need to inspect them.

Maybe you have 10 timestamps that you want to parse or 16 encoded strings that all have the same key. The 'Fork' operation found in the 'Flow control' category splits up the input line by line and runs all subsequent operations on each line separately. Each output is then displayed on a separate line. These delimiters can be changed, so if your inputs are separated by commas, you can change the split delimiter to a comma instead.

Click here for an example. The 'Magic' operation uses a number of methods to detect encoded data and the operations which can be used to make sense of it. A technical description of these methods can be found here. If you find a bug in CyberChef, please raise an issue in our GitHub repository explaining it in as much detail as possible. Copy and include the following information if relevant.

A simple, intuitive web app for analysing and decoding data without having to deal with complex tools or programming languages. CyberChef encourages both technical and non-technical people to explore data formats, encryption and compression. Digital data comes in all shapes, sizes and formats in the modern world — CyberChef helps to make sense of this data all on one easy-to-use platform.

The interface is designed with simplicity at its heart. Complex techniques are now as trivial as drag-and-drop. Simple functions can be combined to build up a "recipe", potentially resulting in complex analysis, which can be shared with other users and used with their input. For those comfortable writing code, CyberChef is a quick and efficient way to prototype solutions to a problem which can then be scripted once proven to work.

It is expected that CyberChef will be useful for cybersecurity and antivirus companies. It should also appeal to the academic world and any individuals or companies involved in the analysis of digital data, be that software developers, analysts, mathematicians or casual puzzle solvers. It is hoped that by releasing CyberChef through GitHubcontributions can be added which can be rolled out into future versions of the tool.

There are around useful operations in CyberChef for anyone working on anything vaguely Internet-related, whether you just want to convert a timestamp to a different format, decompress gzipped data, create a SHA3 hash, or parse an X.

CodeChef was created as a platform to help programmers make it big in the world of algorithms, computer programming, and programming contests. At CodeChef, we work hard to revive the geek in you by hosting a programming contest at the start of the month and another smaller programming challenge in the middle of the month.

CodeChef Long Challenge is a day monthly coding contest where you can show off your computer programming skills. The significance being - it gives you enough time to think about a problem, try different ways of attacking the problem, read the concepts etc.

We also put in a lot of efforts in getting quality problems, which would, in turn, foster your learning while solving them. The idea behind these programming contests is that we want you to learn while competing. Also we believe that it is alright to refer to tutorials, books and other materials, learn a concept and then apply the same to solve a problem during a contest.

But it is not alright to copy other people's solutions or seek other people's help to solve a problem without understanding it. The dividing line may seem to be thin but it can be captured by the spirit of learning. If whatever you are doing is making you learn while you do so, we tend to believe that it is alright.

However, if you are using any other online development environment, make sure that other contestants don't have access to your code. As a contestant, you are responsible for making sure others don't access the code that you submit.

If you use Ideone, make sure to mark your submission "private" not secret ". Due to the large number of submissions, and the number of test files in this problem, this will take a long time, possibly a couple of days.

Ratings will be updated post this rejudge. Sorry for the delay. The problems have been moved to the practice section. Solutions are public for all the problems. Ranklist will be recalculated and Laddus will be provided post ratings calculation. We will reopen the contest atonly for these two problems, for an additional 2. It has been reverted back to the original file, and all submissions made between 10am and pm IST today will be rejudged. All submissions made till now will be rejudged once the contest ends, so that even those submissions are not evaluated on these 4 test files.

From now onwards, your submissions will be evaluated only on the 5 'live' test files. The 10 'non-live' test files will be added after the contest, and all submissions will be rejudged on all the 15 test files again to get the final score. If your solution somehow gets an AC on all the 5 live test files, but gets a non-AC on the remaining 10, during the contest you will get an AC verdict, but after the rejudge that would change to a non-AC verdict when it is evaluated on the remaining 10 files.

If you have a randomized solution without a constant seed, your score on the 5 live test files could change after the rejudge.

This post will show you how to get in the top 10 list. I will also try to do some post-mortem analysis of why the first place wasn't mine. I like to win. I didn't know I like it until I started winning. Besides the good feeling, high ranking on a global competition looks really good on my CV.

Imagine job interviewer reading your CV and there's your university degree. Mhm, says the interviewer.

Then he looks down and pauses Top 10 in global competition? Think about it. Okay, so you would like to win. How do you go about it? The first thing to notice is that all the winners always solved all 10 problems in the contest. Usually around players get all 10 problems right in any given contest.

It means that just by solving all 10 problems you are already securing high ranking for yourself. The problems are all solvable using information freely available on the Internet.

Mostly it's graph theory, search trees, Conway's theory of games, combinatorics, and the usual dynamic programming and greedy algorithms. Basics of these theories are taught routinely at universities and at various courses. But the basics aren't enough. You will have to do some research. Often all the necessary information is in a couple Wikipedia articles. Sometimes you can find various useful bits on other sites or in various PDFs published by university teachers.
