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 ...

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 ...

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 ...

I decided to see how practical it would be to mine Bitcoin with pencil and paper. It turns out that the SHA-256 algorithm used for mining is pretty simple and can in fact be done by hand. Not ...

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) ...

How mining works is fascinating. When I explain it to people, I enjoy seeing their face the moment their mind is blown. I’ll explain it here, but just know, I’m imagining all your faces as your minds ...

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 ...

Security researchers at the CWI institute in Amsterdam working with a team from Google Research say they have found a faster way to compromise the SHA-1 hash algorithm — announcing what they describe ...
