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 ...

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 ...

The RC4 and SHA-1 algorithms have taken a lot of hits in recent years, with new attacks popping up on a regular basis. Many security experts and cryptographers have been recommending that vendors ...

Windows 7 and Windows Server 2008 users will imminently have to deploy a mandatory patch if they want to continue updating their systems, as spotted by Mary Jo Foley. Currently, Microsoft's Windows ...

Whole areas of modern computing rely on the concept of certain things being “computationally infeasible” including encryption. “Computationally infeasible” means mean that certain mathematical ...

No one considers the 20-year-old SHA-1 hash function secure, and browser makers are well on the way to phasing it out. But until yesterday's revelation by researchers at Google and CWI Amsterdam, ...

Yesterday’s Patch Tuesday release also included an update to Microsoft’s Internet Explorer and Edge browsers officially ending support for the SHA-1 hash function. Going forward, both browsers will ...

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 ...

When a paper demonstrating the first known SHA-1 collision was published last month, it caused quite a stir among the tech community. SHA-1 is still an extremely popular form of encryption, and ...

Since my start in 2008, I've covered a wide variety of topics from space missions to fax service reviews. At PCMag, much of my work focused on security and privacy services, as well as a video game or ...
