That's actually going to give you really funky results, because some
of those bytes won't necessarily map to known characters in your
current encoding. Here's the method I use:
public static String toHexString(byte[] _digest) {
StringBuffer hexString = new StringBuffer();
for (int i = 0; i < _digest.length; i++) {
String hexDigitStr = Integer.toHexString(0xFF & _digest[i]);
if (hexDigitStr.length() == 1) {
hexString.append("0");
}
hexString.append(hexDigitStr);
}
return hexString.toString();
}

Hi,
AFAIK java's arrays don't override java.lang.Object's toString()
method, so you get a textual representation of the internal object
ID. To get a String from an array of bytes you should use the
public String(byte[] bytes)
constructor. So try
String calculatedMd5 = new String(result);
instead of result.toString().
HTH,

my function:
String calculateMd5 (String message)
{
MessageDigest myMAC = MessageDigest.getInstance("MD5");
byte[] messageBytes=message.getBytes();
myMAC.update(messageBytes);
byte[] result = myMAC.digest();
String calculatedMd5=result.toString();
return calculatedMd5;
}
I ALWAYS GOT A STRING LIKE "[B@6afa2"
any help?
Thanks
