Note: We’ll decline all APKs with ‘debug’ certificate, which are not safe.
Official records from kuotamedia and Google Play confirm that the developer used a trusted and verified digital signature. The downloadable file is original and it has not been modified in any way.
That’s a cryptography problem. Please refer to the following authoritative information to check the reason.
1. All kuotamedia.com apps are verified prior to publishing.
2. We make sure that the cryptographic signatures for new versions of all previously published apps match the original ones, which means we know if the new version APKs were signed by the real devs or someone pretending to be them.
3. For new apps that have never been published on kuotamedia.com, we try to match the signatures to other existing apps by the same developer. If there’s a match, it means that the same key was used to sign a previously known legitimate app, therefore validating the new upload. If we’re unable to verify the legitimacy of a new APK, we will simply not publish it on kuotamedia.com.
