Generate a new JKS/Keystore

Method 1 - Using Terminal

1. Run the following command in your terminal

      keytool -genkey -v -keystore android/<JKS FILE NAME>.jks -alias <ALIAS NAME> -keyalg RSA -keysize 2048 -validity 10000

• Example command:

    keytool -genkey -v -keystore android/example.jks -alias example -keyalg RSA -keysize 2048 -validity 10000

Here,

• JKS File Name: example
• Alias Name: example

The command will generate a JKS file in your android directory. The validity of the keystore certificate is set to 10,000 days. If you don't add "-validity <NumberOfDays>", the default value will be 90 days.

Note: If you encounter an error like 'Command 'keytool' not found', you'll also receive a suggestion to install keytool. Follow the suggestion and execute the command to install 'keytool'.

After installing keytool, run the 'keytool' command again and complete the process again.
