Atbash and Caesar Cipher Spring Boot

Overview

An implementation of Atbash and Caesar cipher algorithm as a Spring Boot application.

Pre-requisites

This project has the following dependencies,

• Java JDK 11
• Spring Boot 2.3.4

Usage

In this repository, we implement the Atbash and Caesar cipher algorithms. To use these algorithms, we have the following view functions:

• /atbash/encrypt for Atbash encryption. The request parameter for this function is text.
• /atbash/decrypt for Atbash decryption. The request parameter for this function is text.
• /caesar/encrypt for Caesar encryption. The request parameters for this function are text and key.
• /caesar/decrypt for Caesar decryption. The request parameters for this function are text and key.

To run this app, we can use Maven:

$ ./mvnw spring-boot:run

We can call our API in Python through the following manner,

>>> import requests
>>> r = requests.get("http://localhost:8080/atbash/encrypt?text=hello")
>>> r.status_code
200
>>> r.text
'SVOOL'
>>> r = requests.get("http://localhost:8080/atbash/decrypt?text=svool")
>>> r.text
'HELLO'
>>> r = requests.get("http://localhost:8080/caesar/encrypt?text=hello&key=2")
>>> r.status_code
200
>>> r.text
'JGNNQ'
>>> r = requests.get("http://localhost:8080/caesar/decrypt?text=jgnnq&key=2")
>>> r.text
'HELLO'

We can call our API using curl command in the following manner,

$ curl -s -X GET "localhost:8080/atbash/encrypt?text=hello"
SVOOL
$ curl -s -X GET "localhost:8080/atbash/decrypt?text=svool"
HELLO
$ curl -s -X GET "localhost:8080/caesar/encrypt?text=hello&key=2"
JGNNQ
$ curl -s -X GET "localhost:8080/caesar/decrypt?text=jgnnq&key=2"
HELLO
