Rc4 stream cipher c++

WebDec 20, 2024 · The cryptographic algorithm, known as ARC4 ( A lleged RC4 ), is a stream cipher that is widely used in various information security systems on computer networks (for example, SSL and TLS protocols, WEP and WPA wireless security algorithms). The original RC4 stream cipher was created by Ronald Rivest of RSA Security. WebApr 11, 2024 · The RC4 algorithm is a trade secret of RSA, but was leaked to several mailing lists and newsgroups in the mid-90s. People with access to real implementations of the RC4 algorithm have subsequently confirmed its authenticity . The RC4 stream cipher is a lightweight encryption algorithm that is fast, and small, with low energy consumption .
