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.

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 ...

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 ...

Microsoft has warned developers to stop using the RC4 and SHA-1 algorithms. The algorithms have been a source of attacks lately and many have suggested phasing them out, now Redmond has wade in ...

Microsoft is officially moving to shut the door on RC4 - a legacy cryptographic cipher that has quietly persisted inside Windows authentication environments for decades - and forcing organizations to ...

There’s an old saying in the security community: Attacks always get better. The latest case where that holds true is for the aging RC4 cipher that’s still widely used to encrypt communications on the ...

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 ...

SSL/TLS encryption once again is being haunted by an outdated and weak feature long past its prime: a newly discovered attack exploits a weakness in the older, less secure RC4 encryption algorithm ...

Microsoft released optional security updates Tuesday for various versions of the .NET Framework that prevent the RC4 encryption algorithm from being used in TLS (Transport Layer Security) connections.

A proprietary algorithm developed by RSA Data Security, Inc., RC2 is an alternative to DES. The algorithm expands a single message by up to 8 bytes. RC2 is a block cipher that encrypts data in blocks ...
