I\'m trying to implement an app that will show in a textview all the messages received from Whatsapp. Is there any way to do it? Is it possible to extract all the messages f
Once you have access to the dbcrypt5 file , here is the android code to decrypt it:
private byte[] key = { (byte) 141, 75, 21, 92, (byte) 201, (byte) 255,
(byte) 129, (byte) 229, (byte) 203, (byte) 246, (byte) 250, 120,
25, 54, 106, 62, (byte) 198, 33, (byte) 166, 86, 65, 108,
(byte) 215, (byte) 147 };
private final byte[] iv = { 0x1E, 0x39, (byte) 0xF3, 0x69, (byte) 0xE9, 0xD,
(byte) 0xB3, 0x3A, (byte) 0xA7, 0x3B, 0x44, 0x2B, (byte) 0xBB,
(byte) 0xB6, (byte) 0xB0, (byte) 0xB9 };
long start = System.currentTimeMillis();
// create paths
backupPath = Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/WhatsApp/Databases/msgstore.db.crypt5";
outputPath = Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/WhatsApp/Databases/msgstore.db.decrypt";
File backup = new File(backupPath);
// check if file exists / is accessible
if (!backup.isFile()) {
Log.e(TAG, "Backup file not found! Path: " + backupPath);
return;
}
// acquire account name
AccountManager manager = AccountManager.get(this);
Account[] accounts = manager.getAccountsByType("com.google");
if (accounts.length == 0) {
Log.e(TAG, "Unable to fetch account!");
return;
}
String account = accounts[0].name;
try {
// calculate md5 hash over account name
MessageDigest message = MessageDigest.getInstance("MD5");
message.update(account.getBytes());
byte[] md5 = message.digest();
// generate key for decryption
for (int i = 0; i < 24; i++)
key[i] ^= md5[i & 0xF];
// read encrypted byte stream
byte[] data = new byte[(int) backup.length()];
DataInputStream reader = new DataInputStream(new FileInputStream(
backup));
reader.readFully(data);
reader.close();
// create output writer
File output = new File(outputPath);
DataOutputStream writer = new DataOutputStream(
new FileOutputStream(output));
// decrypt file
Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
SecretKeySpec secret = new SecretKeySpec(key, "AES");
IvParameterSpec vector = new IvParameterSpec(iv);
cipher.init(Cipher.DECRYPT_MODE, secret, vector);
writer.write(cipher.update(data));
writer.write(cipher.doFinal());
writer.close();
} catch (NoSuchAlgorithmException e) {
Log.e(TAG, "Could not acquire hash algorithm!", e);
return;
} catch (IOException e) {
Log.e(TAG, "Error accessing file!", e);
return;
} catch (Exception e) {
Log.e(TAG, "Something went wrong during the encryption!", e);
return;
}
long end = System.currentTimeMillis();
Log.i(TAG, "Success! It took " + (end - start) + "ms");
