Hash functions are a fundamental component in digital signatures, password security, random number generation, message authentication and blockchains.

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.

NIST issued several new hash functions (SHA-2) in 2002. They are, generally speaking, more secure than SHA-1, since the size of the hashes (fingerprints) are much larger, and so the expected ...

This process is likely to result in all sorts of new research results in hash function security, and some real cryptanalytic surprises. Give the community a few years to figure out which ones are ...

The coinventor of “bcrypt” is reflecting on the ubiquitous function’s 25 years and channeling cybersecurity’s core themes into electronic dance music.

Bitcoin, for example, uses the hash function SHA-256 in its proof-of-work. (SHA stands for "secure hash algorithm.") Several published, industry vetted hash functions are readily available for use.

Starting with PHP 7.2, released on Thursday, Argon2 v1.3 has been added to the PHP core, and developers can use it via the password_hash () function. // Argon2i with default cost factors ...

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 ...

Thursday's watershed attack on the widely used SHA1 hashing function has claimed its first casualty: the version control system used by the WebKit browser engine, which became completely corrupted ...
