Just to reiterate from a post I made later. There's a (very, very, very...) few places where SHA1 is not broken. But there's no reason ever to use it for new ...

NIST recently published a journal article named "Finding Bugs in Cryptographic Hash Function Implementations," detailing how NIST revisited its five-year SHA-3 competition to find the successor to the ...

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 ...

Gua sha helps because it improves blood circulation in the targeted area of the body, Moy says. This improved blood flow promotes healing. It also helps rid the body of toxins and waste. In ancient ...

Download this article in PDF format. On the surface, this sounds ridiculous: A lobby fish tank gets attacked by hackers. Why would anyone want to break into a fish tank (Fig. 1)? But in this case, the ...

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 ...

This is an explanation of the Cryptography problem "It is my Birthday 2" from CyLab Security Academy (formerly picoCTF). You are provided with one file, invite.pdf. There is a form on the webpage to ...

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 ...

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 ...
