In Python cryptography, how do I stream data?

In Python cryptography, streaming data can be achieved using different libraries, depending on the nature of the data you want to encrypt or decrypt. The `cryptography` library allows you to work with various encryption algorithms that support streaming. Below is an example demonstrating how to encrypt data in a stream using the `Fernet` symmetric encryption method from the `cryptography` library.

This example illustrates how to use the `cryptography` library in Python to encrypt and decrypt data streams efficiently. Learn to secure your data in real time.

# Example of streaming data encryption with Fernet from cryptography.fernet import Fernet # Generate a key for encryption key = Fernet.generate_key() cipher = Fernet(key) # Simulating streaming data data_stream = [b'segment1', b'segment2', b'segment3'] encrypted_stream = [] # Encrypt each segment of data for data in data_stream: encrypted_segment = cipher.encrypt(data) encrypted_stream.append(encrypted_segment) # Now to decrypt decrypted_stream = [] for encrypted_data in encrypted_stream: decrypted_segment = cipher.decrypt(encrypted_data) decrypted_stream.append(decrypted_segment) print("Encrypted Stream:", encrypted_stream) print("Decrypted Stream:", decrypted_stream)
