Developers of two open source code libraries for Secure Shell—the protocol millions of computers use to create encrypted connections to each other—are retiring the SHA-1 hashing algorithm, four months ...

For the last five years, NIST, the government body charged with developing new standards for computer security, among other things, has been searching for a new hash function to replace the aging ...

The National Institute of Standards and Technology has chosen the five finalists for the last round of its competition to find the next hash function standard. The SHA-3 finalists include Skein, ...

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. This shows that the algorithm ...

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 ...

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 ...

Hash algorithms are widely used to store passwords in a (relatively) secure manner by converting various length plaintexts into standard length scrambles in a manner that cannot mathematically be ...

But there it's not applied as a security measure. For integrity it doesn't really matter, the only issue there is a random collision and that's still as unlikely as ever. It's pretty much impossible ...
