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 ...

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.

In the realm of computer science, it’s hard to go too far without encountering hashing or hash functions. The concept appears throughout security, from encryption to password storage to crypt… ...

Hashing is a cryptographic process that makes it harder for attackers to decrypt stored passwords, if used correctly.

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 ...

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.
