RC4 is a stream cipher and variable-length key algorithm. This algorithm encrypts one byte at a time (or larger units at a time). A key input is a pseudorandom bit generator that produces a stream ...

The RC4 and SHA-1 algorithms have taken a lot of hits in recent years, with new attacks popping up on a regular basis. Many security experts and cryptographers have been recommending that vendors ...

This repository contains a C++ implementation of the RC4 encryption algorithm along with several tests to explore weaknesses in the algorithm. RC4 is a symmetric key stream cipher widely used in ...

Abstract: RC4 algorithm is a famous stream cipher. It could be used to encrypt images quickly and efficient. However, the RC4 has been proved has some drawbacks, therefore it is considered not secure ...

About time: Microsoft introduced support for the RC4 stream cipher in Windows 2000 as the default authentication algorithm for the Active Directory services. The system has been insecure for even ...

A fresh warning concerning the use of RC4 to support secure communication channels online has been issued after researchers were able to exploit the protocol to decrypt user data in mere hours.

Misty-eyed old-timers are mourning the passing of one of the world’s most elegant encryption algorithms. RC4 was designed by Ron Rivest in the late 1980s. Initially, RC4 was a proprietary trade secret ...

Google and Mozilla today announced they’ve settled on a timeframe to permanently deprecate the shaky RC4 encryption algorithm. Google, Microsoft and Mozilla today announced they’ve settled on a ...

Researchers have demonstrated that attacks against the RC4 cryptographic algorithm are becoming more practical and feasible than ever. Despite being very old, RC4 is still one of the most widely used ...
