--------------------------! The 1989 International Obfuscated C Code Contest (IOCCC) had an entry by Brian Westley. Applying ROT13 to the transformed file returns the original. rot13 /rot ther’teen/ /n.,v./ [Usenet: from `rotate alphabet 13 places’] The simple Caesar-cypher encryption that replaces each English letter with the one 13 places forward or back along the alphabet, so that “The butler did it!” becomes “Gur ohgyre qvq vg!” Most Usenet news reading and posting programs include a rot13 feature. Thus, ROT13 can be used as a very simply method of encoding and decoding text files. It is a special case of Caesar Cipher in which shift is always 13. Performs the ROT13 encoding on the string argument and returns the resulting string. Thus, ROT13 can be used as a very simply method of encoding and decoding text files. World's simplest ROT13 tool. I was going to go after a mathematical implementation that probably would've This means that to undo Rot13 you use the same algorithm. Can I assign any static IP address to a device on my network? Encoded string: ABJURER nowhere 123. How @Michael said this char out[alen] is not accepted by the compiler because you can't declare an array size with a non constant value. You must use a pointer to the start of the string as argument of the function, because You can't return arrays in C (But you can return pointers ). A ROT13 function that uses a switch. Basically, I want to rotate every letter in args[]... c rot13. ROT13 (rotate by 13 places) replaces a letter with the letter 13 letters after it in the alphabet. Because there are 26 letters in the basic Latin alphabet, ROT13 is its own inverse; that is, to undo ROT13, the same algorithm is applied, so the same action can be used for encoding and decoding. It has been described as the "Usenet equivalent printing an answer to a quiz upside down" as it provides virtually no cryptographic security. Remember that ROT13(ROT13(x)) == x! It is used to hide potentially offensive jokes, or to obscure an answer to a puzzle or other spoiler. $ echo "test" | python -c 'import sys; print sys.stdin.read().encode("rot13")' share | improve this answer | follow | edited Mar 26 '11 at 14:57. answered Mar 26 '11 at 13:58. kurumi kurumi.

It's used on USENET to post material that may be offensive - the reader has to choose to convert it back to plain text. Method 1: C++ program to encrypt and decrypt the string using Caesar Cypher Algorithm. As the Caesar Cipher, and as every monoalphabetical cipher, it doesn't offer any security as it is easy to break it. as Antoine Mathys points and as pointed in my answer, the transform is not correct. Applying ROT13 to the transformed file returns the original. ** May you find forgiveness for yourself and forgive others. Or does it have to be within the DHCP servers (or routers) defined subnet? In ROT13 you should only be changing the alphabetic characters, hence you need the second else if to check if it's at the last half of the alphabet. C++ Language Add Digits of any Number To add digits of any number in C++, we enter the number to add their digits & displays the "Addition Result" of the digits of the entered number on the output screen as shown here Finding The Transpose of Martix in Sparse C Programming code finding the transpose of a martix in sparse form.

Perhaps the most extreme version of this wordplay is Brian Westley’s entry to the 1989 International Obfuscated C Code Contest. It’s also a type of substitution cipher, because one letter is substituted for another. Here it is: I'm not going to count it as the official version for three reasons. The 1989 International Obfuscated C Code Contest (IOCCC) had an entry by Brian Westley. Brian wrote a piece of C code which would compile either as written, or when encrypted using ROT13. ROT13 is a C program which reads a file and makes a copy in which all characters have been "rotated" by 13 positions, and all digits have been "rotated" by 5 positions. ended up like the one shown above, except that I just couldn't figure it out. ROT-13 is a letter substitution cypher that replaces a letter with the letter 13 letters after it in the alphabet.ROT-13 is an example of the Caesar cypher with the difference that Caesar cypher allows you to specify the number of letters to shift.. Main method: The algorithm … Making statements based on opinion; back them up with references or personal experience. ROT13 cipher (stands for "ROTation 13") is a simple monoalphabetical cipher. Rot13 simply adds 13 to the value of each character, and wraps around back to "A" when it gets to "Z".

ROT13 to text: ROT13 encoder and decoder. URL encode Binary to base64 Integer encoder Enigma decoder A1Z26 cipher Cryptii. A becomes N, B becomes O and so on. Its operation, when executed, is either to perform ROT13 encoding on, or to reverse its input. ROT13 is a special case of the popular Caesar cipher. For example, a shift of one would mean all B’s in a text would be replaced with A’s. But since I am not very familiar with that language, I have some problems with my code right here. Where is my implementation of rot13 in JavaScript going wrong? I am trying to learn C and I came across the ROT13 scrambling system used to store some passwords.
