WebRC4 didesain oleh Ron Rivest yang berasal dari RSASecurity pada tahun 1987. RC sendiri mempunyaisingkatan resmi yaitu "Rivest Chiper", namun jugadikenal sebagai “Ron’s Code” RC4 sebenarnyadirahasiakan dan tidak dipublikasikan kepada khalayakramai, namun ternyata ada orang yang tidak dikenalmenyebarkan RC4 ke mailing list "Cypherpunks ... WebJun 3, 2014 · RC4 is implemented in two main phases: 1. A Key Scheduling Algorithm is executed using a symmetric key to create an array of 256 bytes (0x100h). 2. This array is then used in a pseudo-random number generation algorithm to generate a cipher stream that can be decoded using the same key.

WebNov 5, 2012 · 2. RC4 is a stream cypher, so it uses XOR to encrypt. Running RC4 produces a random looking keystream of bytes. To encrypt you do: plaintext XOR keystream -> cyphertext. To decrypt you do: cyphertext XOR keystream -> plaintext. In both cases the keystream is the same, produced from RC4 using the same key. Share.

Encryption is vulnerable to a bit-flipping attack … WebApr 25, 2016 · First RC4 is not a block cipher, is a stream cipher. Second, the decryption is exact the same as the encryption, as the algorithm generates the ciphertext by XORing the plaintext with some stream obtained using the key, and XOR is reversible, meaning: to decypher just need to XOR the ciphertext with the same generated stream.
