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) ...
SAN FRANCISCO, Calif — A team of three Chinese researchers have compromised the SHA-1 hashing algorithm at the core of many of today's mainstream security products. Top cryptographers said users ...
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 ...
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 ...
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 ...
Bringing to a close a five-year selection process, the U.S. National Institute of Standards and Technology (NIST) has selected the successor to the encryption algorithm that is used today to secure ...
Things are about to get a lot safer on the internet with SHA-2, but there is plenty of work still to be done when it comes to SHA-1 deprecation. For the past couple of years, browser makers have raced ...
What is the Q-Day prize? The Q-Day Prize is a challenge to make the Bitcoin network quantum resistant. On April 16, 2025, quantum computing-focused company Project 11 announced the “Q-Day Prize,” a ...
You're about to click on a download button and notice a weird looking code next to it. It doesn't seem to have anything to do how big the file is or whether it's ...
