How to encrypt decrypt files with python (GnuPG)

In this video, we'll explore how to use GnuPG (GNU Privacy Guard) with Python to encrypt and decrypt files. GnuPG is a free and open-source implementation of the OpenPGP standard, which provides encryption and digital signature capabilities. Python is a popular programming language that is widely used in various fields, including scientific computing, data analysis, and web development.

First, we'll learn how to generate GnuPG keys using python. We'll create a pair of keys: a public key that can be shared with others to encrypt messages, and a private key that is used to decrypt messages. We'll also learn how to export and import keys between different machines.

Next, we'll dive into Python code and use the python-gnupg library to interact with GnuPG from within Python. We'll learn how to use GnuPG to encrypt a file using a recipient's public key and then decrypt the file using the recipient's private key. We'll also explore how to sign a file with our own private key to prove that it was indeed authored by us.

By the end of this video, you'll have a solid understanding of how to use GnuPG with Python to secure your files and communications. Whether you're a developer, a data scientist, or a privacy-conscious individual, this video will help you take your security game to the next level.
