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.

Mac

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

WIndows

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

• Enter your details and remember the password. After this, you will get an key.jks Keystore file.

• Locate this file and move the file into the android/app folder and copy the path by right-clicking on the key.jks file.

• Then go to the android/key.properties​ file and replace the path of your Keystore file. Then also replace the ​password​ that 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

Your alias_name is key and keystore_location is the path(directory) of the key.jks file.

• After that, you will get a SHA1 & SHA256 codes. Copy these codes and add them to your Firebase Console > Project Settings > Android, where you previously added a debug SHA1 code.
