First, it is important to ensure that all SSL connections are made using strong cryptography. This means using strong algorithms, such asSHA-256orSHA-512, and ensuring that all keys have a length of at least 2048 bits. Additionally, verifying the server’s identity before making an SSL connec...
The first parameter in the function would be the string that needs to be encrypted. The second parameter needs to be the key, which will be used for the decryption purpose. Use the Cryptography Package to Encrypt a String in Python Cryptography is a Python package that can be used to achie...
For more convenient use of encryption and decryption of files, I suggest you read this tutorial which uses the cryptography module that is more friendly to Python developers.Now let's combine our functions into a single one:def encrypt_decrypt_file...
