An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

"You're storing the passwords in plaintext?" My college professor looked at me puzzled. I had to immediately fix this. It was a huge security problem in my senior ...

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 ...

If you want to read up on hash tables, may I recommend Cormen, Leiserson, and Rivest's Introduction to Algorithms. Knuth also has an detailed analysis of them in section 6.4 in Vol III of his Art of ...

Hash functions are a one-way mathematical problem. If a person has the resulting hash, it is impossible to convert it back to the original data. In this episode of “Bitcoin, Explained,” hosts Aaron ...

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...
