Encrypt Files and Strings with Python Using Symmetric Encryption

🖼Subscribe to our Channel! https://www.youtube.com/channel/UCLJyEZXnEuMgXqtS0sJgBFg ------- In this video, you will learn how to encrypt and decrypt data and strings in Python. This is Part I: Symmetric encryption with the cryptography library in Python. For more information, visit us on: - https://github.com/pmahon2016/symmetric_encryption.git in this video we're going to talk about encryption which is really important today when managing certain data and thankfully there are libraries available for python to handle encryption so in this video, we're going to learn how to encrypt text and files in python. First, a quick primer on encryption. In general before we begin there are basically three types of encryption; symmetric encryption has a single key that is shared between two or more people think of the key is the password. Symmetric encryption is great for encrypting files and large amounts of data quickly. Asymmetric encryption has two keys; a public and a private key and there's a relationship between the two keys that allow you to encrypt with one key and decrypt with the other. This is ideal for transmitting data or, when managing keys is difficult. Finally, there's a one-way hash which does not use keys - it only encrypts and does not decrypt. So then, each type of encryption specializes in a particular function but they are often used together in the cipher suite in this video we're only going to look at symmetric encryption with the Python encryption library. We will look at the other types in future videos from this series
