This article is the result of my own research into interesting trick: encrypting base64 encoded payload via RC4. WebbRC4 is an example of a modern symmetric-key stream cipher. It was developed in 1987 by Ron Rivest, one of the developers of the public-key cipher RSA. RC4 is a trademark. RC2, RC5, and RC6 are symmetric-key block ciphers. RC4 does not generate its keystream by using a LFSR. For RC4, stream combinations are done on byte-length strings of plaintext. best jojo villains rankedWebb1 Simplified RC4 Example Lets consider the stream cipher RC4, but instead of the full 256 bytes, we will use 8 x 3-bits. That is, the state vector S is 8 x 3-bits. We will operate on 3-bits of plaintext at a time since S can take the values 0 to 7, which can be represented as 3 bits. best jokes 2022
