First, you need to install the enMailing app from the Google Play store on your Android device.

When you first run the enMailing app, you’ll see the below welcome screen:

Android Welcome Screen

Tap “Next” to set up an email account. The app will allow you to type in the email address and password for the email account you want to use:

Android Email Account

This information is used on your Android device so that the enMailing app can retrieve your email, just like any other email app you use on that device. Information about your email account is not transmitted to enMailing. Enter your email address and password, and tap the “Next” button. If you have a common email provider, the app should be able to configure your email account without any additional settings. Once the app has configured your email account, you will get a chance to name the account and provide your name:

Android Email Settings

It’s a good idea to give the account a meaningful name if you plan to use multiple email accounts in the enMailing app. In the second box, you have the opportunity to enter your name. This is the name that the people who receive email messages from the app will see. Once you’ve filled in these boxes (or not), tap the “Next” button. This will bring you to the enMailing device authentication screen:

Android enMailing Auth

Enter in your enMailing username and password. Also, provide a meaningful device name for this Android device. Entering in a name that is as specific as possible will make it easier for you to manage your authorized devices down the road. You can largely ignore the “Full Access” checkbox for now. In the future, that option will allow you to manage your enMailing account from your Android device. That feature hasn’t been added in yet, though. If that’s something you’ll be interested in, you can check the box and it should become an option once we add the feature. After you’ve entered in your enMailing username, password, and device name, tap the “Authorize” button. If your enMailing account information is correct, the setup wizard will complete and you will be shown the accounts screen. If you don’t want to authorize the device, you can bypass this step by tapping the “Done” button.

From the accounts screen, you can select which email account to view (if you’ve added multiple). Select the email account you wish to view, and you will be taken to that account’s inbox. The function of the app will be familiar to you if you’ve used any other email app on your device before. When you first open an encrypted message, it will look like this:

Android Encrypted Message

If you’ve authorized your device, and you have the access to decrypt that message, it will automatically decrypt shortly:

Android Decrypted Message

When composing messages, you have a couple different options for encrypting what you write. Here’s the compose screen:

Android Compose Message

If you want to encrypt the message, click the enMailing icon in the upper right. This will display the enMailing toolbar:

Android Compose enMailing

If you check the “Encrypt on send” checkbox, the app will encrypt the entire message when you send it. If you tap where the above picture says “Everyone” you will have the option to select the group for which you want to encrypt your message. You can refresh your list of groups by tapping the “Refresh groups” button. If you only want to encrypt a portion of your message, select the text you want to encrypt as shown below:

Android Compose Encrypt Selection

Once you have selected the text you want to encrypt, tap the “ENCRYPT” button in the selection toolbar, as shown in the upper right corner of the picture above. That will encrypt the selected text for the currently selected group:

Android Compose Decrypt

If you want to decrypt the text you’ve encrypted, just tap the “Decrypt” button on the enMailing toolbar, shown above, and all encrypted text will be decrypted for you to edit.
