SHA-1 is one of the most prevalent forms of a secure hash algorithm used in the legal and security industry. Now that Professor Xiaoyun Wang and her associates in Tsinghua University and Shandong ...

Since my start in 2008, I've covered a wide variety of topics from space missions to fax service reviews. At PCMag, much of my work focused on security and privacy services, as well as a video game or ...

In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

In the realm of computer science, it’s hard to go too far without encountering hashing or hash functions. The concept appears throughout security, from encryption to password storage to crypto, and ...

For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death’s door. Now it’s officially dead, thanks to the submission of the first known instance of ...

The cryptography world has been buzzing with the news that researchers at Google and CWI Amsterdam have succeeded in successfully generating a 'hash collision' for two different documents using the ...

People have been working on perfecting hashing since computing's early days. The result has been an almost endless number of hashing methods and tables. Facebook has faced this problem as well. Within ...
