# 3.4 Generate Release Certificate

To generate a release certificate, You have to generate a Keystore file. To generate a Keystore file, run this command below from the root of your project directory.

{% tabs %}
{% tab title="Mac" %}

```
keytool -genkey -v -keystore ~/upload-keystore.jks -keyalg RSA -keysize 2048 -validity 10000 -alias upload
```

{% endtab %}

{% tab title="WIndows" %}

```
keytool -genkey -v -keystore c:\Users\USER_NAME\upload-keystore.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias upload
```

{% endtab %}
{% endtabs %}

* Enter your details and remember the **password**. After this, you will get an **upload-keystore.jks** Keystore file.
* Locate this file and move the file into the **android/app** folder and copy the **path** by right-clicking on the upload-keystore.jks file.
* Then go to the **android/key.properties**​ file and replace the **path** of your Keystore file. Then also replace the ​**password​** which you have inputted to generate the Keystore file.

Now you can generate a release certificate, To do that,

* Run with replacing your **alias\_name** and **keystore\_location**.

```
keytool -list -v -keystore keystore_location -alias alias_name
```

{% hint style="info" %}
Your alias\_name is **upload** and keystore\_location is the path(directory) of the **upload-keystore.jks** file.
{% endhint %}

* After that, you will get a **SHA1** code. Copy that code and add it to your **Firebase Console > Project Settings >  Android**, where you previously added a debug SHA1 code.
