In cryptography, RC4 (Rivest Cipher 4, also known as ARC4 or ARCFOUR, meaning Alleged RC4, see below) is a stream cipher. While it is remarkable for its simplicity and speed in software, multiple vulnerabilities have been discovered in RC4, rendering it insecure. It is especially vulnerable when the beginning of the … See more RC4 was designed by Ron Rivest of RSA Security in 1987. While it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" (see also RC2, RC5 and RC6). See more RC4 generates a pseudorandom stream of bits (a keystream). As with any stream cipher, these can be used for encryption by combining it with … See more As mentioned above, the most important weakness of RC4 comes from the insufficient key schedule; the first bytes of output reveal information about the key. This can be … See more • TEA, Block TEA also known as eXtended TEA and Corrected Block TEA – A family of block ciphers that, like RC4, are designed to be very simple to implement. • Advanced Encryption Standard • CipherSaber See more Unlike a modern stream cipher (such as those in eSTREAM), RC4 does not take a separate nonce alongside the key. This means that if a … See more • WEP • TKIP (default algorithm for WPA, but can be configured to use AES-CCMP instead of RC4) • BitTorrent protocol encryption • Microsoft Office XP (insecure implementation since nonce remains unchanged when documents get modified ) See more • Paul, Goutam; Subhamoy Maitra (2011).

ISBN 9781439831359. • Schneier, Bruce See more WebData will be encrypted plaintext is called, the data generated from the encryption process is called the chiphertext. In this research used a method that uses symmetric cryptographic key as a password in the encryption process and use the same key for decryption process that will produce the same data with original data plaintext.
