OutputStreaminstance to be used as the destination for the encrypted content
key- the byte array containing the key for encryption
off- offset of the key in the byte array
len- the length of the key in the byte array
public void write(byte b, int off, int len) throws IOException
lenbytes from the specified byte array starting at offset
offto this output stream. The general contract for
write(b, off, len)is that some of the bytes in the array
bare written to the output stream in order; element
b[off]is the first byte written and
b[off+len-1]is the last byte written by this operation.
write method of
OutputStream calls the write method of one argument on each of the bytes to be written out. Subclasses are encouraged to override this method and provide a more efficient implementation.
NullPointerException is thrown.
off is negative, or
len is negative, or
off+len is greater than the length of the array
b, then an IndexOutOfBoundsException is thrown.
