Suppose you want to send the message “I LOVE APPLES”, you can replace every letter in the phrase with the third successive letter in the alphabet. 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). One of the key differences between our attacks is how we attack the protocol. The process of transforming information into nonhuman readable form is called encryption. Kali Linux also offers a password cracking tool, John the Ripper, which can attempt around 180K password guesses per minute on a low-powered personal laptop. Creating the Table. To encrypt a message, you need the right key, and you need the right key to decrypt it as well. Since RC4 has many cryptographical weaknesses it may not be necessary to brute force the whole key space. Deciphering is reversing a cipher into the original text. We proceed by comparing your hash with our online database, which contains more than 1.000.000.000 different hashes. Everything below is based on personal research and reading papers, books and a lot of different scripts or programs. hashcat currently supports CPUs, GPUs, and other hardware accelerators on Linux, Windows, and OSX, and has facilities to help enable distributed password cracking.

WEP involves two parameters, an Initialization Vector (IV) which is a three (3) byte value and shared WEP Key of hexadecimal digits for encryption and decryption. RC4 / ARC4 encryption and decryption online. As with any stream cipher, these can be used for encryption by combining it with the plaintext using bit-wise exclusive-or; decryption is performed the same way (since exclusive-or with given data is an involution). Applications such as wireshark, tshark and airdecap have supported this for quite some time. Give our rc2 encrypt/decrypt tool a try! This will likely increase the file size for non-text data. RC4 was initially a trade secret, but in September 1994 a description of it was anonymously posted to the Cypherpunks mailing list. Just in case your Linux distribution doesn’t already have GnuPG, you can install it by opening a terminal, and searching for “gpg”. By default a user is prompted to enter the password. Let’s illustrate this with the aid of an example. We will use 00 00 00 as the encryption key. Because of the flaws in the RC4 algorithm, an attacker can relatively easily gather data and cross-check that data to decrypt messages and even gain network access. These are not problems with the tool itself, but inherent problems with pentesting and password cracking in general. aes-192-cfb1.
