Simple way to salt passwords. For best results (and consistent sizes for database storage) hash the resulting string.

gistfile1.txt

    private static String saltIt(String passphrase) {
        String saltChars = "i08q4h0fn23in2034qnvosysag01n40!$#@#$^@#$#ESDGASFXBSDFHDFH2";
        char[] salt = saltChars.toCharArray();
        StringBuilder stringBuilder = new StringBuilder();
        stringBuilder.append(passphrase);
        for (char s : salt) {
            stringBuilder.append(s);
            stringBuilder.append(passphrase);
        }

        return stringBuilder.toString();
    }

Be sure to change the saltChars string before you re-use this code!
