安卓加密

安卓图片加密，视频加密，文本加密，一切文件，甚至给APP加密也可以，只不过解密比较麻烦

public static void jiami(String b,String c,String d,String word) throws IOException{

File file2=new File(d);
if (!file2.exists()) {
file2.createNewFile();
}
FileInputStream fileInputStream=new FileInputStream(b);
FileInputStream fileInputStream1=new FileInputStream(c);
FileOutputStream fileOutputStream=new FileOutputStream(d);
BufferedWriter bufferedWriter=new BufferedWriter(new FileWriter(d,true));
byte[] data=new byte[1024];
byte[] data1=new byte[512];
while ((fileInputStream.read(data))!=-1) {

fileOutputStream.write(data);
while ((fileInputStream1.read(data))!=-1) {
fileOutputStream.write(data);
countstream++;
if (countstream==1) {
fileOutputStream.write(data1);
}
}
}
fileInputStream.close();
fileInputStream1.close();
fileOutputStream.flush();
fileOutputStream.close();
bufferedWriter.write(word);
bufferedWriter.flush();
bufferedWriter.close();

}
