| | | fail to output Document to encrypted file | fail to output Document to encrypted file 2003-12-05 - By ??????
Back
Using "flowfish", I encrypted an xml file which is from a Document instance and
successfully rebuilt the Document instance from the encypted file. Then before
closing my application, I output the Document instance to an encrypted file. The
code is as below, but the resulting file is not all right and seems to lack a
few
bytes(especially the last bytes) after it is decrypted.
try
{
String indent = " ";
boolean newLines = true;
XMLOutputter outp = new XMLOutputter(indent, newLines, "GB2312");
outp.setTextTrim(true);
// doc is a correct Document instance
// catFilePath is a String instance
// cipher is a Cipher instance for encrypting
outp.output(doc,new CipherOutputStream(
new FileOutputStream(catFilePath),cipher));
}
catch (Exception e) {e.printStackTrace();}
If I change indent,newLines,or remove "outp.setTextTrim(true)", the resulting
file
changes a little accordingly.
