The SHA1 (Secure Hash Algorithm 1) cryptographic hash function is now officially dead and useless, after Google announced today the first ever successful collision attack. SHA1 is a cryptographic hash ...

A theoretical scenario that leverages the SHA1 collision attack disclosed recently by Google can serve backdoored BitTorrent files that execute code on the victim's machine, deliver malware, or alert ...

In 2016, tens of millions of people around the world will face trouble accessing some of the most common encrypted websites like Facebook, Google and Gmail, Twitter, and Microsoft sites. Why? Because ...

Attacks on the SHA-1 hashing algorithm just got a lot more dangerous last week with the discovery of a cheap "chosen-prefix collision attack," a more practical version of the SHA-1 collision attack ...

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 ...

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 ...

Microsoft is killing off an obsolete and vulnerable encryption cipher that Windows has supported by default for 26 years ...

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 ...

Microsoft is moving to disable RC4, an encryption cipher embedded in Windows authentication for more than two decades. The decision follows years of documented abuse, repeated warnings from security ...
