About the Tool

This is an Open Source AES Standard encrytion tool.
AES stands for Advanced Encrption Standard. It is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data.

AES encryption has three different block ciphers: AES-128 (128 bit), AES-192 (192 bit) and AES-256 (256 bit). These block ciphers are named after the key length they use for encryption and decryption. All these ciphers encrypt and decrypt the data in 128-bit blocks but they use different sizes of cryptographic keys.

A file (temp_key.txt) for storing the encryption key(s) for file(s)/folder(s) encrypted using the tool is automatically created in the current working directory. Always make sure to backup the encryption key if not the files cannot be reverted back....!!!

Built With

• Python

Getting Started

To run the tool locally,

• Clone the repository. For instructions to clone the repo proceed here.
• Follow these steps on your OS
  • On Linux : Open the terminal and make sure that the present working directory(folder) is the same as the directory containg the File_Encryptor.py file. Check this using the following command

pwd

It will display the path of the current working directory. To display the files/folders in the working directory use the command

ls

To execute the program file use the command :

python3 File_Encryptor.py

Expected output

Working of the tool

File encryption
A file named temp_key.txt is created. It stores the encryption key. Also the name of the encrypted file is changed to name.aes(use this file name for decryption).

File decryption
