Features

• Generate RSA key pairs for encryption and decryption.
• Encrypt files using the recipient's public key.
• Decrypt files using the recipient's private key.
• Generate digital signatures for files using the sender's private key.
• Verify digital signatures using the sender's public key.

Getting Started

Prerequisites

• Python 3.6 or above
• RSA, Pickle, YAML, GZip

Installation

1. Clone the repository:

$ git clone https://github.com/arcaus/rsa.git
$ cd rsa

2. Install the required libraries:

pip install pyyaml

Usage

Encrypting a File

1. Run the script and choose the encryption option.
2. Enter the path of the file you want to encrypt.
3. A new ciphertext.pkl file has been generated with the encrypted data and the signature.

Decrypting a File

1. Run the script and choose the decryption option.
2. Enter the path of the file (ciphertext.pkl) you want to decrypt.
3. You should receive the plaintext along with the verification status.
