A Python implementation of the RC4 Algorithm RC4 is a symmetric stream cipher and variable key length algorithm RC4 generates a pseudo-random stream of bits (a key-stream).

The RC4 and SHA-1 algorithms have taken a lot of hits in recent years, with new attacks popping up on a regular basis. Many security experts and cryptographers have been recommending that vendors ...

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 ...

A paper, expected to be presented at USENIX, describes new attacks against RC4 that make plaintext recovery times practical and within reach of hackers.

Partial plaintext data can be obtained from SSL/TLS communications through an attack that leverages a 13-year-old vulnerability. The attack method has been dubbed Bar Mitzvah.

Encryption algorithms are applied to a variety of fields and the security of encryption algorithms depends heavily on the computational infeasibility of exhaustive key-space search. RC4 algorithm has ...
