Cryptographic hash functions are crucial in ensuring the security and integrity of information across diverse industries. They protect sensitive financial transactions in banking, verify data ...

Last week, the Technology Workgroup of the Massachusetts State HIE Advisory Committee was asked to address an interesting policy and technology question. When a payload of data (a clinical summary, a ...

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 ...

SHA1, one of the Internet’s most crucial cryptographic algorithms, is so weak to a newly refined attack that it may be broken by real-world hackers in the next three months, an international team of ...

This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated. This ...

A replacement for one of the most-used algorithms in computer security has finally been chosen after a competition between cryptographers that ran for five years. The competition was designed to ...

Members can download this article in PDF format. In the last two articles, we covered the basic concepts and two basic types of cryptography. In this article, we will look at specific implementation ...
