pip install rsa pycryptodome

User Guide

Basic RSA

Key Generation

cd Basic_RSA
python RSA_keygen.py [bits]

Replace [bits] with the desired key length in bits. If you don't provide any value, it defaults to 2048 bits.

Encryption

python RSA_encrypt.py [plaintext_file] [ciphertext_file]

Replace [plaintext_file] with the path to the file containing the plaintext and [ciphertext_file] with the path to the file where the ciphertext will be stored.

Decryption

python RSA_decrypt.py [ciphertext_file] [plaintext_file]

Replace [ciphertext_file] with the path to the file containing the ciphertext and [plaintext_file] with the path to the file where the plaintext will be stored.
