Summary:
- Microsoft is finally retiring an old encryption cipher called RC4 that has been used by hackers to break into Windows systems for over a decade.
- RC4 was an outdated encryption method that had many security vulnerabilities, allowing cybercriminals to easily intercept and decrypt data transmitted between computers and servers.
- Removing RC4 from Windows will improve the overall security of the operating system and make it harder for attackers to exploit known weaknesses in the encryption protocol.
