Generate a CSR code for Android apps

CSR is an acronym for Certificate Signing Request, a block of encoded text with contact data every SSL applicant must generate and send to the CA during the certificate enrollment process.

Since Java is the official language of Android development, we’ll show you how to generate a CSR code via Java Keystore. Alternatively, you can use our CSR Generator Tool to automatically create your CSR.

Along with the CSR, Java Keystore will also generate your private key file, required during the SSL installation. Please, follow the instructions below:

  1. To create a keystore and a key file, run the following command:
    keytool -genkey -alias myalias -keyalg RSA –keysize 2048 -keystore c:\yoursite.keystore

    Note: Remember your alias. You will need it later during the SSL installation.

  2. When prompted, submit your information as shown below:
    • What is your first and last name? Instead of your first and last name, enter the FQDN (fully-qualified domain name) you want to secure. For example,
    • What is the name of your organizational unit? Name the department within your organization requesting the SSL Certificate. For instance, IT
    • What is the name of your organization? Specify the full legal name of your company. For example, Your Company LLC
    • What is the name of your city or locality? Write the full name of the city where your company is registered
    • What is the name of your state or province? Enter the full name of the state or province where your company is located For example, California
    • What is the two-letter country code for this unit? Type your country’s official two-letter code. For instance, US. Here you can find the full list of country codes.
  3. Press Y or type Yes to confirm your details
  4. To create your CSR code run the following command:
  5. keytool -certreq -keyalg RSA -alias myalias -file certreq.txt -keystore c:\yoursite.mykeystore
  6. To locate your CSR file, run the command below:
    type certreq.txt
  7. Use any text editor such as Notepad to open the certreq file. You will need to copy-paste its contents, including the BEGIN CERTIFICATE and END CERTIFICATE tags into the corresponding box during the SSL order process.

Install an SSL Certificate on Android

After your CA validates your SSL request and sends the necessary SSL files to your inbox, you can proceed with the installation.

Before you begin, your SSL files meet the Android requirements:

  • Android only supports DER-encoded X.509 SSL certificates
  • Android support PKCS#12 key store files with .pfx or .p12 extension
  • You’ll have to create a PKCS#12 password or passphrase
  • If your certificates’ extension is not in .cer or .crt format, you will have to convert them, using an SSL Converter tool
  • SSL is supported by all Android’s older and newer versions

Please, follow the steps below to being your installation:

  1. On your Android admin dashboard go to Settings > Security
  2. Under Credential Storage click on Install from Phone Storage/Install from SD Card

    Note: if you don’t have this option, navigate to Advanced Settings > Security or Advanced Settings > Privacy and click on Install from Phone Storage/Install from SD Card.

  3. The File Storage Manager will appear. Locate your SSL Certificate from your device
  4. If prompted to enter the PKCS#12 password, type the password you created
  5. In the Certificate Name field, enter a friendly name for your certificate
  6. Under Credential Use select VPN and Apps or Wi-Fi based on your security requirements.

Congratulations, you’ve successfully installed an SSL Certificate on Android.
