A hash is a unique string of characters generated by a mathematical function, used to represent data and ensure its integrity in cryptography and blockchain technology.

A cryptographic hash function is a mathematical algorithm that takes an input (or 'message') and returns a fixed-length string of characters ...

NIST has opened a competition to develop a new cryptographic hash algorithm, a tool that converts a file, message or block of data to a short "fingerprint" for use in digital signatures, message ...

SHA1 algorithm securing e-commerce and software could break by year’s end Researchers warn widely used algorithm should be retired sooner.

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.

Such hash algorithms are ultimately one of the key security technologies for federal and public systems. The competition is NIST’s response to recent advances in the analysis of hash algorithms.

You can’t un-ring a bell, but you might be able to un-hash an email, depending on whom you ask. In order for marketers to safely use hashes for targeted advertising, they must stay abreast of the ...
