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 ...

Windows operating system updates are dual-signed using both the SHA-1 and SHA-2 hash algorithms to prove authenticity. But going foward, due to "weaknesses" in SHA-1, Microsoft officials have said ...

Fifteen-year-old Peter Schmidt-Nielsen spent only a month working on his submission, but he thinks he’s come up with something “unusual and new.” Never mind that he’s up against some of the most ...

Microsoft recently described its timeline for phasing out Secure Hash Algorithm-1 (SHA-1) in supported Windows systems, and for upgrading to SHA-2. The details on patching systems to support SHA-2, ...

Currently all Windows updates are dual signed with both SHA-1 and SHA-2 code signing certificates. As there are flaws in the SHA-1 algorithm that make it less secure, Microsoft has stated that ...

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 ...

Millions of Web users could be left unable to access websites over the HTTPS protocol if those websites only use digital certificates signed with the SHA-2 hashing algorithm. The warning comes from ...

Windows 7 and Windows Server 2008 users are being asked to upgrade their encryption support. Microsoft is in the process of phasing out use of the Secure Hash Algorithm 1 (SHA-1) code-signing ...
