SHA (Secure Hash Algorithm) The basic idea behind a SHA function is to take data of a variable size and condense it into a fixed-size bit-string output. This concept is called hashing .

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.

This insane virtual arms race has revealed that it is extremely hard to develop secure cryptographic algorithms (it’s easy to write broken cryptographic algorithms), and it appears that hashing may be ...

NIST issued a Call for a New Cryptographic Hash Algorithm (SHA-3) Family in a Federal Register Notice on Nov. 2, 2007. The announcement specifies the submission requirements, ...

As the U.S. Department of Commerce's National Institute of Standards and Technology (NIST) prepares to announce the winner of its competition to find the next-generation cryptographic hash ...

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...

With a strong hash function it is almost impossible to reverse the hash value to its original content. The National Security Agency (NSA) designed the SHA-1 cryptographic hash function 10 years ago.

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 ...

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 ...
