Hash Function: A computational algorithm that transforms an input (or 'message') into a fixed-size string of characters, commonly known as a digest, structured to be computationally infeasible to ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental ...

Strong, Efficient, and Cost-Effective Security Hash algorithms turn a digital message into a short message digest for applications such as digital signatures.

The digests are meant to be distinct for every message, file and function. Any string of text or data will, in theory, produce a unique SHA-1 hash.

SHA-3 hashing is part of the NIST-endorsed FIPS 202 standard and serves as a future-proof backup for the widely-used SHA-2 algorithms. Hashing algorithms transform digital data such as messages, ...

The National Institute of Standards and Technology (NIST) this week opened a competition to develop a new cryptographic hash algorithm, a tool that converts a file, message or block of data to a ...

Algorithms can be used to create a digest, or a cryptographic string that is representative of a piece of data. The digest created by a hash function is based on the characteristics of a document.

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature.
