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 ...

Google is encouraging businesses and security practitioners to utilize cryptographic hashes like SHA-256, a Secure Hash Algorithm which serves as the basis of the Bitcoin network’s proof of work (PoW) ...

Right now there are thousands of computers connected to the Internet, dutifully calculating SHA-256 hashes and sending their results to other peers on the Bitcoin network. There’s a tremendous amount ...

The latest version of Linus Torvalds' Git version-control system brings experimental support for the SHA-256 cryptographic hash, moving it away from its reliance on the less safe SHA-1. Google and ...

Could an IBM mainframe from the 1960s mine Bitcoin? The idea seemed crazy, so I decided to find out. I implemented the Bitcoin hash algorithm in assembly code for the IBM 1401 and tested it on a ...

Ever wonder how long it would take to mine a block into the Bitcoin blockchain by hand? Well, wonder no longer because blogger Ken Shirriff has done the work for you with a pencil and paper. In an ...

The SHA-256 hash function remains a cornerstone of modern cryptographic systems, underpinning applications ranging from blockchain mining to secure communications in IoT networks. Recent advancements ...

Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...

It has been revealed that the update system of the embedded Linux distribution ' OpenWrt ' had a vulnerability that could cause malicious packages to be mistaken for genuine packages. The SHA-256 hash ...
