encrypt a column in a table using Python

Encrypting a column in a table is a common security practice to protect sensitive data in databases. In this tutorial, I'll guide you through the process of encrypting a column in a table using Python. We'll use the cryptography library, which provides a simple interface to encrypt and decrypt data securely.
Install cryptography library: You can install it using pip:
Database Connection: Assume you have a database with a table that you want to encrypt a column in. Make sure you have the necessary credentials and connection details.
Replace the placeholders with your database connection details.
Assuming you have a table named your_table and a column named column_to_encrypt, fetch the data you want to encrypt.
You'll need this key to decrypt the data later. Save it securely.
Now, the data in the specified column of your table is encrypted. Remember to keep the encryption key secure, as it's essential for decrypting the data when needed. Also, make sure to handle key management properly in a production environment.
