A collection of Cipher implementations in different langauges.

What is a cipher?

In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.

Why this repository?

Learning cipher algorithms and getting started with open source contribution are the two main ojectives of this repository.

Steps to get started and make your pull request...

1. FORK THE REPO Forking the repository(repo) makes a copy of someone else's project as your own to start working on it.

2.Clone To start coding and making changes in the repository, you need to have the project locally on your local machine.Use the command below to clone(download) the project.

$ git clone https://github.com/happycoder0011/CIPHER_DIARIES.git

Note: To clone in a particular folder, run the below command first then clone command.

cd folder_name

3.Enter project folder

cd CIPHER_DIARIES

4.Set Up to contribute Run the below command to check wether your local copy has the reference to the forked remote repository on github.

git remote -v 

You should get an output similar to

origin  https://github.com/Your_user_name/CIPHER_DIARIES.git (fetch)
origin  https://github.com/Your_user_name/CIPHER_DIARIES.git (push)

If not!! Check that you are in the right folder of the project. Otherwise fork again and reiterate the steps.

Add a reference to the original CIPHER_DIARIES repo:

git remote add upstream  https://github.com/happycoder0011/CIPHER_DIARIES.git

Check if it's added

git remote -v

You should get output as

origin  https://github.com/Your_user_name/CIPHER_DIARIES.git (fetch)
origin  https://github.com/Your_user_name/CIPHER_DIARIES.git (push)
upstream   https://github.com/happycoder0011/CIPHER_DIARIES.git (fetch)
upstream   https://github.com/happycoder0011/CIPHER_DIARIES.git (fetch)

Voila!!! Set up done.

Start by adding your files, codes and commit to your copy of the project.

Command to commit

git add .
git commit -m "commit message"
git push origin master

Note: You would be working on your local project. Always make sure to pull the repo before pushing your code to see the changes made by other contributors.

git pull

After you have successfully pushed your code on your remote copy(github) of the project. You can compare the branch with the original repo on github and make a pull request!

cipher_diaries's Issues

Add decryption methods Caeser Cipher and update documentations.

Hi, I have noticed that the caeser cipher scripts don't have any decryption method. I have already pushed a PR adding those decryption methods. If it's accepted, I would like to update the README.md extensively too. What do you think about this?

Add readme.md for Vingenere Cipher

Explain the encryption and decryption technique

Implement Affine Cipher in C/ C++

Hello, I have noticed that there is no implementation of Affine Cipher in C/ C++. I would like to contribute to it. Could you please add the required labels?

@happycoder0011

Add readme.md for substitution cipher

Explain the encryption and decryption technique

Hacktoberfest2020 Add Hill Cipher implementation in Java to the repository

Add readme.md for caesar cipher

Explain the encryption and decryption technique

Add readme.md for autokey_cipher

Explain the encryption and decryption technique.

README.md for RSA cipher

Hello, I have noticed that there is no README.md for the RSA ciphers. I would like to contribute if it helps meaningfully 😃

Add readme.md for hill cipher

Explain the encryption and decryption technique

Implement Playfair Cipher in C++

Including Implementation of Playfair Cipher in C++ Language

Hacktoberfest2020 Add Vigenère Cipher

Add Vigenère Cipher to the repository

Implement RSA Cipher in JavaScript

Implement Playfair Cipher in JavaScript

Add Autokey Cipher in Python

Will add a single python file to encrypt AND decrypt the entered text as demanded by the user.

Add readme.md for Playfair cipher

Elaborate about the algorithm

XOR Cipher in python/cpp

XOR Cipher in CPP or python has not added yet. Really like to work on it.

Add readme.md for Railfence cipher

Add readme.md for Transposition cipher

Explain the encryption and decryption technique

Implement Substitution Cipher in JavaScript

Implement Railfence Cipher algorithm in JavaScript

Substitution Cipher in C

Two files with Same Name that leads to confict while cloning repo

There are two files with the same name in the ROT13_Cipher folder.

file1: ROT13.c
file2: rot13.c

Changes Required : Delete any one file from the above-mentioned files.

Implement Transposition Cipher in JavaScript

Added rot13 in cpp

Is there any problem with the #45 pull request because I have followed all the rules. Can you provide any feedback @happycoder0011 .

A template for PRs

I believe that having a basic template for PRs would help people contribute more efficiently and prompt them to adopt more standard practices while writing codes. In many of the repos, I have seen the maintainers provide a small checklist for this. What do you think?

Add PlayFair Cipher

I would like to add a python program for PlayFair Cipher for both encryption and decryption.

Add readme.md for ROT13 cipher

Explain the encryption and decryption technique

Implement hill cipher in C++

Implement Hill Cipher in JavaScript

Edit Substitution Cipher

The current implementation of the substitution cipher is identical to the Caesar cipher, which may not be as desired. I would like up to update the implementation to allow the user to perform a simple substitution cipher on the plaintext with a custom key of their choice.

Please assign me this task, and if possible, add the Hacktoberfest label to this issue.

Thank you!

Implement XOR Cipher in cpp

Implement Affine Cipher in JavaScript

ROT13 in Python

It seems like a ROT13 implementation in Python hasn't been added yet. I'd really like to work on this.

Add Railfence Cipher in Python

Have coded Railfence cipher (both encryption and decryption) in python based on user input. Would like to add it to this repository.

Implement Substitution Cipher in C++

added rot13 in c programming

add rot13 cipher algorithm in c programming #52 please check.
