Well, not that I like that Tom's interface too much...

Anyway, what you get is MD5 as 16 binary bytes stored in String.

What you need to do is to convert them one by one to hex to get the result.

E.g. (not quite optimal speedwise):

String x = MD5Digets(...);
String r;
for(int i = 0; i < x.GetCount(); i++)
  r << FormatIntHex(x[i], 2);

should work.

thx for the fast answer, but the code doesn't work,

program does create very long string, aprox 70-80 char

	String x = MD5Digest("alajos");
	String r;
	for(int i = 0; i < x.GetCount(); i++) {
		r << FormatIntHex(x[i], 2);
	}
	
	Cout() << r << '\n';

result:

4c681e2952ffffff88ffffffbfffffffde2058360bffffffb2ffffffddffffffe6ffffffbb

this code does work, but very ugly Smile

	String x = MD5Digest("alajos");
	String r;
	for(int i = 0; i < x.GetCount(); i++) {
		int a = 0;
		char * ptr = (char*)&a;
		*ptr = x[i];
		r << FormatIntHex(a, 2);
	}
	
	Cout() << r << '\n';

Sorry:

	String x = MD5Digest("alajos");
	String r;
	for(int i = 0; i < x.GetCount(); i++)
		r << FormatIntHex((byte)x[i], 2);

(need to cast to (byte), otherwise char converts to negative integers...)
