Usually the `debug.keystore` password is just &quot;**android**&quot;.

You can delete it and Eclipse will automatically generate a new one, as described [here](https://stackoverflow.com/a/2196397/4230345).

**The Default Configuration of debug.keystore file:**

    Keystore name: &quot;debug.keystore&quot;
    Keystore password: &quot;android&quot;
    Key alias: &quot;androiddebugkey&quot;
    Key password: &quot;android&quot;
    CN: &quot;CN=Android Debug,O=Android,C=US&quot;

**Where is this file located?** 

For Windows users: `C:\Users\[username]\.android\debug.keystore`

For macOS users: `~/.android/debug.keystore`

You can get the SHA1 by using the following command:

```sh
keytool -list -v -keystore &quot;C:\Users\[username]\.android\debug.keystore&quot; -alias androiddebugkey -storepass android -keypass android
```

Note: The above answer has just information of Android Studio&#39;s default configuration to access the `debug.keystore` (debug certificate). You can make a custom certificate if you want to use your own password or configuration.

If you are not certain that the password has been set before, try just empty password. It worked for me.

Again you can generate your google api key. Your .keystore file will be, 
In Eclipse, Windows -&gt; preferences -&gt;Android -&gt; build -&gt;default debug keystore path will be there. You just use that .keystore and generate your api key again by using this link:

Suppose I have a pandas data frame `df`: 

I want to calculate the column wise mean of a data frame.

This is easy: 

    df.apply(average) 

then the column wise range max(col) - min(col). This is easy again: 

    df.apply(max) - df.apply(min)

Now for each element I want to subtract its column&#39;s mean and divide by its column&#39;s range. I am not sure how to do that

Any help/pointers are much appreciated.

I have 2 pages: `xyz.com/a` and `xyz.com/b`. I can only access `xyz.com/b` if and only if I login to `xyz.com/a` first. If accessing `xyz.com/b` without going through the other, I simply get access denied (no redirect to login) via the browser. Once I login at `xyz.com/a`, I can access the other.

My problem is doing this using the curl command. I can login successfully to `xyz.com/a` using curl, but then try `xyx.com/b` and I get access denied.

I use the following:

    curl --user user:pass https://xyz.com/a  #works ok
    curl https://xyz.com/b #doesn&#39;t work

I&#39;ve tried using the second line with &amp; without the user/password part and still doesn&#39;t work. Both pages uses the same CA, so that&#39;s not a problem. Any suggestions? Thanks

The app doesn&#39;t crash, but there&#39;s a black screen and the device doesn&#39;t react to pressing the &#39;back&#39; or &#39;home&#39; buttons.

Does anyone know what the problem is?

How to take a screenshot of other app programmatically without root permission, like Screenshot UX Trial?

 1. I know I can capture the bitmap of the root view in my app. But I can&#39;t get the root view of the other app when my app is running in background

    `bitmap = Bitmap.createBitmap(rootview.getDrawingCache());`

 2. There is a permission for capturing current frame buffer in Manifest: `android.permission.READ_FRAME_BUFFER`. But some website says it&#39;s for signature app only.

    [Check Android Permissions - Protection Levels][1]

After trying Screenshot UX Trial, I read the permission:

- INTERNET: for connect to localhost screenshot server for rooted phone.
- SYSTEM_ALERT_WINDOW: for topmost camera button.
- VIBRATE: for vibrate feedback.
- WRITE_EXTERNAL_STORAGE: to save the screenshot.
- GET_TASKS: for detect foreground Develoment setting activity for non rooted&amp;non preloaded capture method.

It seems either `SYSTEM_ALERT_WINDOW` or `GET_TASKS` allow the app to take screenshot.
I have two guess of how it works:

 1. It may be able to access the `Activity` of the foreground activity, it gets the root view of the `Activity`, capture its screenshot.
 2. Calling `glreadpixels`

If you try one of my guess, please let me know the result.

I am implementing a demo for RSA Encryption and Decryption in Android. I can Perform Encryption very well, but In Decryption I get an Exception: `&gt;&gt;java.security.InvalidKeyException: unknown key type passed to RSA`.
    

        KeyPairGenerator kpg;

SHA-1 fingerprint of keystore certificate

As I was going through some posts on the Internet learning more about *signing your Android app*, I got post like **how to sign the app**, and something about **what if you have lost your keystore file or password.**

The question I am here to ask is that, I have never created a keystore, or its alias, or its password, so how on this earth can I forget it?

I know that for Android we use the password **android**, so, if the password is by default android how can one forget it? (I&#39;m sure there must be some other way to create new keystores).

Finally, if android is the default password, **what is the default alias?**

I have never set any passwords to my keystore and alias, so how are they created?

I&#39;m following [guideline][1] how to sign Android apk with Jenkins. I have parametrized Jenkins job with KSTOREPWD and KEYPWD. A part of Jenkins&#39; job configuration (Build-&gt;Execute shell) is to take those parameters and store them as environment variables:

    export KSTOREPWD=${KSTOREPWD}
    export KEYPWD=${KEYPWD}
    ...
    ./gradlew assembleRelease

The problem is when the build is over anybody can access the build &quot;Console Output&quot; and see what passwords were entered; part of that output:

    08:06:57 + export KSTOREPWD=secretStorePwd
    08:06:57 + KSTOREPWD=secretStorePwd
    08:06:57 + export KEYPWD=secretPwd
    08:06:57 + KEYPWD=secretPwd

So I&#39;d like to suppress echo before output from `export` commands and re-enable echo after `export` commands.

I would like to be able securely store some sensitive strings in the Android KeyStore. I get the strings from the server but I have a use case which requires me to persist them. KeyStore will only allow access from the same UID as that assigned to my app, and it will encrypt the data with the device master password, so it&#39;s my understanding that I don&#39;t have to do any additional encryption to protect my data. My trouble is, I&#39;m missing something about how to write the data. The code I have below works perfectly, as long as the call to KeyStore.store(null) is omitted. That code fails, and as long as I can&#39;t store the data after putting it to the KeyStore, then I can&#39;t persist it.

I think I&#39;m missing something about the KeyStore API, but I don&#39;t know what. Any help appreciated!

    String metaKey = &quot;ourSecretKey&quot;;
    String encodedKey = &quot;this is supposed to be a secret&quot;;
    byte[] encodedKeyBytes = new byte[(int)encodedKey.length()];
    encodedKeyBytes = encodedKey.getBytes(&quot;UTF-8&quot;);
    KeyStoreParameter ksp = null;
    
    //String algorithm = &quot;DES&quot;;
    String algorithm = &quot;DESede&quot;;
    SecretKeyFactory secretKeyFactory = SecretKeyFactory.getInstance(algorithm);
    SecretKeySpec secretKeySpec = new SecretKeySpec(encodedKeyBytes, algorithm);
    SecretKey secretKey = secretKeyFactory.generateSecret(secretKeySpec);
    
    KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
    
    keyStore.load(null);
    
    KeyStore.SecretKeyEntry secretKeyEntry = new KeyStore.SecretKeyEntry(secretKey);
    keyStore.setEntry(metaKey, secretKeyEntry, ksp);
    
    keyStore.store(null);
    
    String recoveredSecret = &quot;&quot;;
    if (keyStore.containsAlias(metaKey)) {
        KeyStore.SecretKeyEntry recoveredEntry = (KeyStore.SecretKeyEntry)keyStore.getEntry(metaKey, ksp);
        byte[] bytes = recoveredEntry.getSecretKey().getEncoded();
        for (byte b : bytes) {

How Can I Use the Android KeyStore to securely store arbitrary strings?

I have searched StackOverflow for a while, but I just wanted to make sure...

I wiped my laptop a while ago, and backed up all my files. I have my android.jks file backed up, and it&#39;s back in place. When I try to generate a signed APK, it&#39;s giving me the same dreaded error everyone is getting:

    Error:Execution failed for task &#39;:app:packageRelease&#39;.
    &gt; Failed to read key conjugationappkey from store     
    &quot;/Users/wasimsandhu/android.jks&quot;: Cannot recover key

I have my android.jks, the key password, the key store password. Everything is correct. What am I missing? I backed up all of my files, so if there is a specific file I need, I could find it, but I have no idea what to do...

If I&#39;m not making any sense, please ask me to clarify. Thanks!
