passing encrypred password from android to web service to mysql database using ksoap2

Question

I'm sending username and password from android app to web service using skoap2, web service connects to MySQL database. it works perfect with password as text, but if I send an encrypted password, I got illegalCharacterException when creating SoapEnvelope. I think I got the idea what is the problem, but I have no idea how can I solve it. in what form (now String) should I pass the encrypted password and how to store it in the database? (will varchar cause same error)?

String password = ((TextView)findViewById(R.id.passwordr1)).getText().toString();
MessageDigest messageDigest = MessageDigest.getInstance("SHA-256"); //$NON-NLS-1$
messageDigest.update(password.getBytes());
String encryptedPassword = new String(messageDigest.digest());

later in the code

SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);

...

PropertyInfo passwordProp =new PropertyInfo();
passwordProp.setName("password");
passwordProp.setValue(params[1]);
passwordProp.setType(String.class);
request.addProperty(passwordProp);

...

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);       
HttpTransportSE ht = new HttpTransportSE(URL);
ht.call(SOAP_ACTION, envelope);
String response = (SoapPrimitive)envelope.getResponse().toString();
