(Very) Basic Intro To Elliptic Curve Cryptography

Elliptic curve cryptography is an efficient modern approach to public-key cryptosystems. In this introduction, our goal will be to focus on the high-level principles of what makes ECC work. We will omit implementation details and mathematical proofs, we can save those for another article. What It’s For? A common use of ECC is to encrypt data … Read more (Very) Basic Intro To Elliptic Curve Cryptography

Why is Exclusive Or (XOR) Important in Cryptography?

If you are getting into cryptography, or just trying to understand the fundamentals, you may have noticed that the exclusive-or operation is used quite often, especially in ciphers. What is XOR (⊕)? XOR, or “exclusive or” operates on binary data. It returns true if both of its inputs are opposites (one false and one true), … Read more Why is Exclusive Or (XOR) Important in Cryptography?
