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 ...

You might not have realized it, but the next great battle of cryptography began this month. It's not a political battle over export laws or key escrow or NSA eavesdropping, but an academic battle over ...

Cryptography secures digital data using algorithms, essential in private secure communications. Cryptos use cryptographic methods like asymmetric encryption and hash functions for transactions.

Phil Goldstein is a former web editor of the CDW family of tech magazines and a veteran technology journalist. He lives in Washington, D.C., with his wife and their animals: a dog named Brenna, and ...

Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...

Bitcoin miners collect and broadcast transactions in a block and verify their validity. Then they apply a cryptographic hash function of the previous block's header to the new block. Finally, they try ...

A method for ensuring that data have not been altered. A hash total is the numerical sum of one or more fields in a file, including data not normally used in calculations, such as account number. The ...
