The module provides constructor methods for each type of hash. Python has a built-in library, hashlib, that is designed to provide a common interface to different secure hashing algorithms. In the next section, you’ll learn how to use the Python hashlib library to implement the SHA256 encryption algorithm.Ĭheck out some other Python tutorials on datagy, including our complete guide to styling Pandas and our comprehensive overview of Pivot Tables in Pandas! Using Python hashlib to Implement SHA256 This allows us to use unique identifiers, even when their data is obfuscated. Two different input values will practically never yield the same result, allowing us to maintain integrity and uniqueness of data.īecause of this, we can identify overlap in records, say, to identify same birthdates, social security numbers, etc.It is a one-way algorithm, meaning that under current technologies, the algorithm cannot be returned to its original value, and.What makes the SHA256 algorithm interesting is that: These functions are have excellent uses in protecting sensitive information such as passwords, personal identifiers such as identification items. The acronym SHA stands for Secure Hash Algorithm, which represent cryptographic hash functions. Using Python hashlib to Implement SHA256īefore we dive into how to implement a SHA256 algorithm in Python, let’s take a few moment to understand what it is.
