I have a program that handles byte arrays in Java, and now I would like to write this into a XML file. However, I am unsure as to how I can convert the following byte array into a sensible String to write to a file. Assuming that it was Unicode characters I attempted the following code:

String temp = new String(encodedBytes, "UTF-8");

Only to have the debugger show that the encodedBytes contain "\ufffd\ufffd ^\ufffd\ufffd-m\ufffd\ufffd\/ufffd \ufffd\ufffdIA\ufffd\ufffd". The String should contain a hash in alphanumerical format.

How would I turn the above String into a sensible String for output?

    If your string is the output of a password hashing scheme (which it looks like it might be) then I think you will need to Base64 encode in order to put it into plain text.

    Standard procedure, if you have raw bytes you want to output to a text file, is to use Base 64 encoding. The Commons Codec library provides a Base64 encoder / decoder for you to use.

    Hope this helps.
