Hacker News上的一篇文章深入探讨了RC4加密算法在Windows认证中的历史演变。尽管RC4早已被业界普遍认为过时，但它却出人意料地持续使用了很长时间。文章指出，RC4本应被更安全的方案淘汰，但BEAST攻击曾短暂导致它回归，该攻击影响了CBC模式的分组密码。如今，最推荐的操作模式是Galois/计数模式（GCM），它能有效将128位分组密码转换为流密码，提升安全性。这一讨论揭示了网络安全领域的实践变迁，为读者提供了关于加密技术演变的宝贵行业洞察，尤其对关注微软产品和前沿安全技术的读者有重要参考价值。

An article on Hacker News delves into the historical evolution of the RC4 encryption algorithm in Windows authentication. Although RC4 has long been widely considered obsolete by the industry, it surprisingly remained in use for a considerable time. The article points out that RC4 should have been phased out in favor of more secure alternatives, but the BEAST attack briefly led to its resurgence, as the attack affected block ciphers in CBC mode. Today, the most recommended mode of operation is Galois/Counter Mode (GCM), which effectively converts a 128-bit block cipher into a stream cipher, enhancing security. This discussion reveals the evolving practices in the network security field, offering readers valuable industry insights into the evolution of encryption technology, especially for those focused on Microsoft products and cutting-edge security technologies.
