This program allows the user to encrypt or decrypt any plaintext or ciphertext file, using a random byte key of their choosing, as long as it is between 5 and 256 bytes so it is complaint with the RC4 ...

Abstract: This paper is focused on the synthesis and simulation of RC4 algorithm, which can be implemented on FPGA. A variable length key from 1 to 16 bytes is used by RC4 algorithm to initialize a ...

RC4 is a stream cipher and variable-length key algorithm. This algorithm encrypts one byte at a time (or larger units at a time). A key input is a pseudorandom bit generator that produces a 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 paper, expected to be presented at USENIX, describes new attacks against RC4 that make plaintext recovery times practical and within reach of hackers. Two Belgian security researchers from the ...

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.

According to a research team from Royal Holloway University London (RHUL) and the University of Illinois at Chicago, when RC4 encryption (long known to be weak) is used as part of TLS/SSL (that is, ...
