funcryption

This is a console app written in Haskell for encrypting and decrypting text according to the following encryption algorithm:

Take every 2nd character from the string, then the other characters, and concat them as a new string. Perform this the required number of times.

Getting started

Prerequisites

You need to have stack build tool installed on your computer to compile the project.

Running the app

Clone the repository.

$ git clone https://github.com/gleb-dianov/funcryption.git

Compile the project.

$ cd funcryption
$ stack build

Run the project.

$ stack exec funcryption

Examples

$ stack exec funcryption
Enter an action (Encrypt or Decrypt): hello?
Invalid action!
$ stack exec funcryption
Enter an action (Encrypt or Decrypt): Encrypt
Enter text: hello?
Enter how many times you want to run the algorithm: hello?
Invalid integer!
$ stack exec funcryption
Enter an action (Encrypt or Decrypt): Encrypt
Enter text: hello?
Enter how many times you want to run the algorithm: 91.7
Invalid integer!
$ stack exec funcryption
Enter an action (Encrypt or Decrypt): Encrypt
Enter text: This is a test!
Enter how many times you want to run the algorithm: 2
s eT ashi tist!
$ stack exec funcryption
Enter an action (Encrypt or Decrypt): Decrypt
Enter text: s eT ashi tist!
Enter how many times you want to run the algorithm: 2
This is a test!

Running the tests

$ stack test
