А так

public void read(ByteBuffer buffer) {
		int size =  buffer.getShort();
		
		int position = buffer.position();
		
		decrypt(buffer, position, size);
		
		int id = buffer.get();

		switch(id) {}
}

public void decrypt(ByteBuffer buffer,int offset,int size) {
		try { //LoginCrypt crypt 
			crypt.decrypt(buffer.array(), offset, size);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
