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 ...

Cryptographic hash functions combine message-passing capabilities needed in database security and cryptocurrency transactions.

A hash is a mathematical function that maps data of arbitrary size to a fixed-size value that is encrypted.

Hash functions transform input text into unique strings of output text. For example, the popular md5 hash function would take the previous sentence as input and generate the following as output ...

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

Among other desirable properties of hash functions, an interesting one is that it should be collision-resistant, that is it should be difficult to find two messages with the same hash value.

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature.

In this episode of “Bitcoin, Explained,” hosts Aaron van Wirdum and Sjors Provoost go back to Bitcoin basics. They explain one of the most fundamental building blocks in all of Bitcoin: hash functions ...
