The algorithm converts it into a scrambled text, which we call “hash”.

An input value is processed through an algorithm.

Let’s review cryptographic hash functions, which are widely used in encryption. I will explain one such example, although remember that there are many ways to encrypt data. Modern encryption uses mathematical algorithms. Even ancient civilizations used it, although we wrongly consider their techniques and tools rather primitive now. How does encryption work?Įncryption isn’t new. We call the process of converting the scrambled text back to the input data – “decryption”. Your data is secure as long as you secure that secret code! Read about it in “ Encryption: what it is and why it’s important”.

Only you, having the secret code to turn that scrambled text back into meaningful information can read your data. If the hackers can’t make any sense of the data, they will not have incentives to steal it in the first place!Įncryption is the technology that turns our sensitive data into scrambled text. What is encryption?Ĭommon people need a way to protect their sensitive data even if it falls into unscrupulous hands. What can people do to protect their data? Answer: Encryption. Then, there are hackers who just breach security mechanisms, and gain access to our data. However, as the massive Facebook-Cambridge Analytica data scandal shows, some unethical businesses do misuse our data. We expect them to use it solely for the purposes we authorize them to. Today, we willingly provide this data to entities including business organizations. Individuals acquire an increasing amount of confidential and sensitive data over the course of their lives. The armaments in this conflict aren’t weapons in the traditional sense, instead, the computer and complex big data analytics have become the main weapons! It’s no wonder that similar conflicts are taking place over our data. Read “ The world’s most valuable resource is no longer oil, but data” if you want to learn more about this interesting observation.Ī brief glance at world history shows us just how many conflicts took place with the sole objective of grabbing natural resources. There is no doubt that it is the most important commodity in our digital era. Some observers contend that data is the new oil. Why make an encryption program? The premium on dataīefore we go deeper into building your own file encryption software, let’s first underline the importance of data.
