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 ...

The National Institute of Standards & Technology (NIST) is set to announce the winning hash algorithm that ultimately will become the next-generation industry standard, SHA-3. But security expert ...

A rainbow table is a large, precomputed table designed to cache the output of cryptographic hash functions to decrypt hashed passwords into plaintext. Rainbow tables were invented by IT expert ...

The past few years have been a bonanza for password breaches as poor deployment or nonexistent encryption practices combined with database and Web application vulnerabilities to SQL injection continue ...

Bitcoin offers an irreversible digital property function that prior to its invention simply did not exist. Understanding Bitcoin is a one-way hash function should make sense because a hash function ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

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 ...
