如果我丢失了密钥库，如何在我的 Android 应用上发布新版本？

Question

I run 2 command

keytool -genkeypair -alias upload -keyalg RSA -keysize 2048 -validity 9125 -keystore keystore.jks

This command create keystore.jks. Export the certificate for that key to PEM format (upload_certificatie.pem). I will attach upload_certificatie.pem and reply Googleplay developer support to reset the upload key for my app.

keytool -genkeypair -v -storetype PKCS12 -keystore my-upload-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 9125

This command create my-upload-key.keystore that will be placed in the ./android/app folder in my react native project.

I lost my old my-upload-key.keystore. Will the above commands help me keep updating my app? Thank you for your help!

Answer 1

The answer to your question is no. When you loose your keystore you cannot make updates to that application. You will have to make a new application in the play store.

Your only other option is to make a new keyfile and contact google support.

You can create a keyfile with the following command (Keystore and JKS are basically the same):

keytool -genkeypair -v -storetype PKCS12 -keystore my-upload-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
