How to sign existing Play Store app built and signed with Animate (AIR) for new App Bundle format.

Report · Jan 19, 2021

Google uses the new App Bundle and requires developers to use the same certificate to sign the bundle.

My apps apk was always signed with a temperary (.p12) certificate generated in Animate.

I've used keytool to convert the p12 to JKS format

keytool -v -importkeystore -srckeystore "TempCert2016.p12" -srcstoretype PKCS12 -destkeystore TempCert2016.jks -deststoretype JKS

Now I should be able to use PEPK.jar supplied by google to make a PEM

java -jar pepk.jar --keystore=TempCert2016.jks --alias=foo --output=TempCert2016.pem --encryptionkey=<KEY>

The problem I'm having is, what was the alias for the temporary p12 certificate generated by Animate in 2016? Or maybe versions before that?

I got the answer using openssl

openssl pkcs12 -info -nodes -in TempCert2016.p12

The 'friendly name' is '1'.
