Cryptography aficionados, say hello to a new hash algorithm backed by the National Institute for Standards and Technology (NIST). Dubbed Keccak (pronounced "catch-ack"), the secure hash algorithm, ...

Learn more about hash functions, including how they protect data integrity and secure blockchain transactions in ...

Last week, the Technology Workgroup of the Massachusetts State HIE Advisory Committee was asked to address an interesting policy and technology question. When a payload of data (a clinical summary, a ...

A replacement for one of the most-used algorithms in computer security has finally been chosen after a competition between cryptographers that ran for five years. The competition was designed to ...

Passwords are the keys to our online identities, and as a result, they’re also near the top of the target list for attackers. There have been countless breaches in the last few years in which ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

Learn about a hash rate, including what it is, how it functions within cryptocurrency networks, and learn to measure it ...

This standard specifies secure hash algorithms, SHA-1, SHA-224, SHA-256, SHA-384, SHA512, SHA-512/224 and SHA-512/256. All of the algorithms are iterative, one-way hash functions that can process a ...
