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 ...

Microsoft is killing off an obsolete and vulnerable encryption cipher that Windows has supported by default for 26 years following more than a decade of devastating hacks that exploited it and ...

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 ...

Instagram is introducing a new tool that lets you see and control your algorithm, starting with Reels, the company announced on Wednesday. The new tool, called “Your Algorithm,” lets you view the ...

This project implements two cryptographic algorithms: RC4, a stream cipher, and AES (Advanced Encryption Standard), a block cipher. Both algorithms are widely used in cryptography for their unique ...

When you create an algorithm, you need to include precise, step-by-step instructions. This means you will need to break down the task or problem into smaller steps. We call this process decomposition.

As organizations face an evolving threat landscape, strengthening Windows authentication is more critical than ever. The deprecation of RC4 (Rivest Cipher 4) encryption in Kerberos is a shift toward ...

Scientists have now sequenced more than two million bacterial and archaeal genomes, outstripping the ability to perform gold-standard searches for genes. LexicMap is a new tool that can scan millions ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Gordon Scott has been an active investor and ...
