Computing the Checksum of a PDF File
Explore how to compute and verify the checksum of a PDF file using Python's hashlib module. Understand different hashing algorithms and implement a lightweight utility to detect file tampering or corruption.
Introduction
Tons of data are being sent over the Internet or other local networks. This data is susceptible to data loss due to network issues or even malicious attacks.
Typically, a checksum is used to ensure that the data received is unharmed and free of errors and losses.
Checksum stands for what
A checksum is the result of running an algorithm, called a ...
