public class RC4

extends iaik.security.cipher.BufferedCipher

Extends the BufferedCipher class for adding a buffering mechanism to the underlying RC4 cipher.

The RC4 method is a stream cipher using a key of variable size. RC4 operates in Output Feedback Mode (OFB), where - in contrast to CFB - the keystream is created independently from the plaintext.

This class only creates a BufferedCipher object for the RC4 cipher. Applications shall use

Cipher.getInstance("RC4", "IAIK");
 

for creating a RC4 cipher object.

Constructor Detail

RC4

public RC4()

Creates a RC4 object by calling the BufferedCipher constructor for the RC4 cipher. This constructor is only internally used for initializing a RC4 Cipher. Applications should not call this constructor to get a RC4 Cipher; they should call one of the Cipher.getInstance factory methods instead.
