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.

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

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.

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, ...

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.

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 ...
