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 ...

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 ...

SHA1, one of the Internet's most crucial cryptographic algorithms, is so weak to a newly refined attack that it may be broken by real-world hackers in the next three months, an international team of ...

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 ...

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, ...

SHA-1 is a cryptographic hash function that underpins various security applications and protocols to help keep the internet safe. Experts, however, have warned for years that it’s out of date. Now, ...

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 ...

A team from Google and CWI Amsterdam just announced it: they produced the first SHA-1 hash collision. The attack required over 9,223,372,036,854,775,808 SHA-1 computations, the equivalent processing ...
