Microsoft will disable RC4 by default in Windows Kerberos, pushing organizations to uncover and eliminate longstanding cryptographic weaknesses hidden in legacy ...

By mid-2026, Windows domain controllers will default to allowing only AES-SHA1, with RC4 disabled unless administrators explicitly re-enable it. Microsoft says eliminating RC4 proved complicated due ...

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.

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 ...

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 ...

RC4 encryption has been cracked for over a decade. Now Microsoft is slowly sweeping the last remnants, such as in Kerberos, away.

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.

In the last section we discussed the potential for optimizing algorithms, which can be done, but sometimes may not result in the type of performance required. As was mentioned, you can always move the ...

The decision to remove RC4 from IE, Edge, Chrome, and Firefox is final nail in the coffin for the vulnerable cryptographic algorithm After years of security experts demanding the RC4 stream cipher be ...

Cryptographic algorithms can be roughly classified in two categories: Encryption algorithms transform an input file into an output file from which it is (quite) impossible to recover the original ...
