Three years ago, Ars declared the SHA1 cryptographic hash algorithm officially dead after researchers performed the world’s first known instance of a fatal exploit known as a “collision” on it. On ...

The National Institute of Standards and Technology today announced a public competition to pick a new cryptographic hash algorithm that would become the new federal information processing standard.

The National Institute of Standards & Technology (NIST) is set to announce the winning hash algorithm that ultimately will become the next-generation industry standard, SHA-3. But security expert ...

Hash Value Explained: In many technology-related discussions—especially those involving memory cards, CCTV footage, or forensic evidence—you may have heard the term “hash value.” While it sounds ...

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 ...

Cryptographic hash functions secure data by providing a unique fixed-length output for each input. These functions are essential in blockchain for data integrity and secure transactions. Understanding ...

The National Institute of Standards and Technology (NIST) has opened a competition to develop a new cryptographic “hash” algorithm, a tool that converts a file, message or block of data to a short ...

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 ...
