In any datastore system, security is paramount. Whether it's a high-frequency trading platform or an AI-driven sales predictor, the data we store carries significant value and confidentiality. Hence, measures like encryption and authorization are pivotal to preserve the integrity and privacy of our data.

Encryption is a method of converting data into a cipher or code to prevent unauthorized access. To illustrate it, imagine you've jotted down all your revolutionary AI insights on a piece of paper. Now, these papers are very confidential, along with the risk of getting into wrong hands. What do you do? You translate (encrypt) these insights into a language only you understand. Now, even if someone gets the papers, they see gibberish. Similar to our datastore, nobody without the correct decryption key can comprehend the data.

Let's explore what we mean by this in Python - here's a tiny script that takes a password and encrypts it using the SHA-256 algorithm. We're using the hashlib library, which is equipped with several encryption algorithms.

The code block creates a hashed version of the password using hashlib and displays it. Keep in mind, unlike encoding and decoding, encryption and decryption are not inversible unless you have the correct keys, contributing to their security.

import hashlib

​

​

if __name__ == "__main__":

  # Defines a password

  password = 'secure-password'

​

  # Encrypts the password used hashlib library

  password_encryption = hashlib.sha256(password.encode()).hexdigest()

​

  # Output encrypted password

  print('Encrypted Password:', password_encryption)
