RSA-cryptography

RSA algorithm for generating public and private keys, encrypt and decrypt messages, and finally, break the message using the brute force algorithm.

Parameters for execution

Generation of public and private keys

--gerarChaves <public_key> <private_key>

Example

--gerarChaves 5 pub.txt priv.txt

Message encryption

--criptografar <public_key> <message_file> <encrypted_message>

Example

--criptografar priv.txt mensagem.txt criptografado.txt

Message decryption

--descriptografar <public_key> <encrypted_message> <decrypted_message>

Example

--descriptografar pub.txt criptografado.txt decifrado.txt

Brute Force for key breaking

--bruteForce <public_key> <private_key> <encrypted_message>

Example

--bruteForce pub.txt priv.txt criptografado.txt
