The MD5 password hash algorithm is "no longer considered safe" by the original software developer, a day after the leak of more than 6.4 million hashed LinkedIn passwords.

Bcrypt turns 25 this year, and Niels Provos, one of its coinventors, says that looking back, the algorithm has always had good energy, thanks to its open source availability and the technical ...

Hashing algorithms are used to secure passwords by taking the plaintext password, passing it through the cryptographic hash algorithm, and then storing the resulting digest, rather than the ...

A hash rate is the measure of the computational power in a proof-of-work cryptocurrency miner, pool, or network. High hash rates equal better odds of winning.

Each time an email address is run through a hashing algorithm, it produces a jumble of numbers and letters which, in theory, cannot be tied back to that email address or the individual it belongs to.

In a call with reporters regarding the new findings, Apple said its CSAM-scanning system had been built with collisions in mind, given the known limitations of perceptual hashing algorithms.

The hashing example above illustrates the use of a cryptographic algorithm to protect data, but it also highlights the fact that anything in the program can become a security issue. The use of ...

And modern hashing techniques like bcrypt and Argon2 don't simply run a password through a function like SHA1, but do so thousands of times, rehashing the resulting data again and again.
