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.

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

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 ...

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.

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 ...

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.
