Example: Crypt2.HashStringENC method

Demonstrates how to call the HashStringENC method. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    CkCrypt2 crypt = new CkCrypt2();

    String s = "får";

    //  The string "får" in utf-8 is composed of these bytes: 0x66 0xC3 0xA5 0x72
    crypt.put_Charset("utf-8");

    crypt.put_EncodingMode("hex_lower");
    crypt.put_HashAlgorithm("sha256");

    //  Get the hex string for the sha-256 hash of the utf-8 byte representation of the string
    String hashStr = crypt.hashStringENC(s);

    Log.i(TAG, hashStr);
