Digital signatures are emerging as a key enabler not only of e-commerce, but also of electronic contracting and legal activity. ... The Secure Hash Algorithm (SHA-1, ...

NIST has opened a competition to develop a new cryptographic hash algorithm, a tool that converts a file, message or block of data to a short "fingerprint" for use in digital signatures, message ...

Secure authentication provides a strong electronic solution to address this threat. Traditionally, authentication systems have relied on symmetric algorithms such as secure hash algorithms [1] that ...

MD5 has since been largely abandoned for use in generating digital signatures, ... we believe that migration from SHA-1 to the secure SHA-2 or SHA-3 hash algorithms should be done sooner than ...

The message digest is input to the digital signature algorithm to generate the digital signature. The hash functions to be used are specified in the Secure Hash Standard (SHS), FIPS 180. FIPS-approved ...

Two open-source Secure Shell libraries have pulled support for the Secure Hash Algorithm 1 (SHA-1), used for the past 20 years to verify the integrity of software, digital signatures and other ...

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 ...

The National Institute of Standards and Technology today announced a public competition to pick a new cryptographic hash algorithm that would become the new federal information processing standard.
