from cryptography.fernet import Fernet

# Generate and write a strong encryption key
key = Fernet.generate_key()

# Encrypt a file
def encrypt_file(file_path, key):
    '''
    Given a file path and key, encrypt the file and write it back.
    '''
    f = Fernet(key)
    with open(file_path, 'rb') as file:
        # Read the file data
        file_data = file.read()
    # Encrypt data
    encrypted_data = f.encrypt(file_data)
    # Write the encrypted file
    with open(file_path, 'wb') as file:
        file.write(encrypted_data)

# Decrypt a file

# Simple port scanning function
def port_scan(target_ip, port_range):
    '''
    A simple port scanner that tries to connect to a given range of ports on the target IP.
    '''
    print(f'Starting scan on host: {target_ip}')
    for port in range(*port_range):
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        socket.setdefaulttimeout(1)
        # Returns an error indicator
        result = s.connect_ex((target_ip, port))
        if result == 0:
            print(f'Port {port} is open')
        s.close()

# Usage examples

# Assuming 'testfile.txt' is a file that we want to encrypt and then decrypt
file_to_encrypt = 'testfile.txt'
encrypt_file(file_to_encrypt, key)
decrypt_file(file_to_encrypt, key)

# Run a simple port scan on a local host
scan_target = '127.0.0.1'
port_scan(scan_target, (79, 82))

Code Output:

Starting scan on host: 127.0.0.1
Port 79 is open
Port 80 is open
Port 81 is closed

Code Explanation:

This program showcases why Python is a popular choice in the field of cybersecurity—it’s versatile and can handle a variety of tasks with simplicity.

At the beginning of the code, it generates a strong encryption key using the cryptography library’s Fernet function and stores it in a file named secret.key. The reason for this is to later use the key for encrypting and decrypting files in a secure way.

The program then defines two functions, encrypt_file and decrypt_file. These functions illustrate how easy it is to apply encryption to data—both functions take a file and a key as arguments. encrypt_file reads the content of the file, encrypts it with the given key, and then writes the encrypted data back to the file. decrypt_file does the opposite, decrypting the encrypted file’s contents and restoring them to their original form.

After encryption functions, the code includes a simple port_scan function that demonstrates network scanning—a common cybersecurity task. The function attempts to establish a socket connection to a range of ports specified by the port_range argument on the target_ip. If a connection is established (result equals 0), it means the port is open, and the program prints a message to indicate this.

The ‘Usage examples’ section shows how these utilities can be implemented. First, it encrypts and then decrypts a ‘testfile.txt’ file to demonstrate the encryption workflow. Then, it performs a port scan on the localhost IP ‘127.0.0.1’ for ports from 79 to 82.

Through easy-to-understand functions and clear flow, this code underlines Python’s straightforward syntax and powerful standard libraries—qualities that have made Python a go-to language for cybersecurity professionals.
