openssl req -config "PATH_TO_OPENSSL_CONFIG" -new -key key.pem -out request.pem
openssl x509 -req -days 9999 -in request.pem -signkey key.pem -out certificate.pem
openssl pkcs8 -topk8 -outform DER -in key.pem -inform PEM -out key.pk8 -nocrypt

To just sign an existing apk with certificate.pem and key.pk8 provided in bin folder, run below commands:
