Encryption Web Application

This project is a web application that allows users to encrypt and decrypt text using various SHA algorithms. The application is built with a Go backend and a simple HTML/CSS frontend.

Features

• Encrypt text using SHA-256, SHA-384, and SHA-512 algorithms
• Decrypt text by looking up the original text from a list of previously encrypted values
• Maintain a history of encrypted/decrypted values
• Simple and clean user interface

Requirements

• Go 1.22+
• PostgreSQL 16
• A web browser

Installation

1. Clone the repository:

git clone https://github.com/Saracomethstein/encryption.git
cd encryption

2. Run the Go application:

make run

The application will start on http://localhost:8000.

Usage

Encrypting Text

1. Open the application in your web browser.
2. Select the encryption function (Encrypt) by clicking the corresponding button.
3. Select the SHA algorithm (SHA-256, SHA-384, or SHA-512) by clicking the corresponding button.
4. Enter the text you want to encrypt in the input field.
5. Click the START button.
6. The encrypted text will appear in the output field and will be added to the history table.

Decrypting Text

1. Open the application in your web browser.
2. Select the decryption function (Decrypt) by clicking the corresponding button.
3. Enter the SHA value you want to decrypt in the input field.
4. Click the START button.
5. If the SHA value exists in the history, the original text will appear in the output field and will be added to the history table. If the SHA value does not exist, a message indicating the absence of the key will be shown.
