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 National Institute of Standards and Technology retired one of the first widely used cryptographic algorithms, citing vulnerabilities that make further use inadvisable, Thursday. NIST recommended ...

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.
