public ARCFour()
| Method Detail |
public void setKey(byte[] key)
key - The RC4 key used during encryption.
public void write(byte aByte,

throws IOException
aByte - The byte to encrypt.output - The stream to write to.
IOException - If there is an error writing to the output stream.
public void write(byte[] data,
OutputStream output)
throws IOException
data - The data to encrypt.output - The stream to write to.
IOException - If there is an error writing to the output stream.
public void write(InputStream data,
OutputStream output)
throws IOException
data - The data to encrypt.output - The stream to write to.
IOException - If there is an error writing to the output stream.
public void write(byte[] data,
int offset,
int len,
OutputStream output)
throws IOException
data - The data to encrypt.offset - The offset into the array to start reading data from.len - The number of bytes to attempt to read.output - The stream to write to.
IOException - If there is an error writing to the output stream.
