Encrypt and decrypt alphanumeric input.

Dan Murphy's Caesar Cipher

For the lovely people at DrugDev

The exercise

Write code, in your choice of language, that takes as input a string and integer shift and returns that string encoded using a basic Caesar cipher.

Instructions

First, if you don't have Node.js you'll need to install it:

• You can do a manual install from here: https://nodejs.org/en/. This will include Node and its package manager, npm.

• If you are on a Mac and using Homebrew you can do the following:

  • brew install node --without-npm (npm and Homebrew don't play well together)
  • curl -L https://www.npmjs.com/install.sh | sh (so, install npm separately)

• Or if you fancy a version manager download nvm: https://github.com/creationix/nvm

Once you've got Node installed:

• git clone [e-mail]:Murphydbuffalo/caesar-cipher.git
• cd ./caesar-cipher
• npm install to install dependencies
• npm test to run the test suite
• Check out cipher.js to see the code
• Check out the repo to see the git history: https://github.com/Murphydbuffalo/caesar-cipher
• Email Dan at [e-mail] with questions or comments :)
