Hi all,
i am doing encryption by using fileinput and fileoutputstreams, i am
able to encrypt one file and write the encrypted contents to second
file.
but now i want to change it, encryption will be done on a single file
no second file will be created.
so i changed the FileInputStream and FileOutputStream pointing to the
same file but in this my encryption works fine but when i am clicking
on button to encrypt then My file will get empty.
can someone please check the code if something is missing:
Encryption part:-----
in = new FileInputStream("/mnt/sdcard/abc.txt");
fout = new
FileOutputStream("/mnt/sdcard/abc.txt");
out = new CipherOutputStream(fout,cipher);
int num = 0;
buffer = new byte[1024];
while((num = in.read(buffer)) >=0)
{
out.write(buffer, 0, num);
}
in.close();
out.close();
fout.close();
encSuccess.setText("File Encrypted Successfully");
Input and Outputstreams are same beacause i have to write the
encrypted contents to the same file.
Please correct my code if i am doing something wrong.
Thanks
