📝 Android Signing
keytool -list -v -keystore signing-key.keystore to verify that it is a valid keystore.
openssl base64 < signing-key.keystore | tr -d '\n' | tee signing-key.keystore.base64.txt //encrypt
base64 -d signing-key.keystore.base64.txt > signing-key.keystore //decrypt
so you want to use the playstore app signing and you want to upload your own key certificate, i mean the one you used in signing your android app via the build stage.
run the following command to generate the certificate.pem from your keystore
sudo keytool -export -rfc -keystore signing-key.keystore -alias YOURKEYSTOREALIAS -file upload_certificate.pem
