Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ciphertext.

Hash functions are cryptography’s most widely used primitives, in that they are a fundamental building block used for a wide variety of constructions. The recent attacks of Joux, Wang, and others ...

Before we move into the meat of this article, let’s define a couple terms related to cryptography. The syllable crypt may make you think of tombs, but it comes from a Greek word that means “hidden” or ...

To answer your question, I need to step through various aspects of cryptography. One type of cryptographic algorithm is called a hash function. Hash functions take a message of any length as input and ...
