Google Play App Signing: upload key versus app signing key
Tests Android signing infrastructure and key escrow knowledge. A strong answer states Google holds the app signing key while you retain an upload key, protecting critical signing material. Red flag: claiming both keys sign the final install artifact.
Tests your understanding of Android signing infrastructure, key escrow, and supply chain security. A strong answer explains that Google permanently manages the app signing key used for end user installs, while the developer only holds an upload key to authenticate bundles to Play. This separation ensures the critical signing key is never stored on developer machines or CI systems, reducing breach impact. Red flag: believing the upload key is what devices verify at install time or that losing it requires a new app listing.
