Android Question Warning of deactivation of SHA1withDSA keystore in the near future

[mohsen programmer]

Hello,
I made a app with B4A two years ago. Now when verifying the signature of the program with jdk, this warning is displayed:
The certificate uses the SHA1 with DSA signature algorithm which is considered a security risk. This algorithm will be disabled in a future update.
The certificate uses a 1024-bit DSA key which is considered a security risk. This key size will be disabled in a future update.

Does this mean I won't be able to update my app in the future?
My app has 10 million users and this warning worries me, what should I do?

This warning comes from Java. Not from Android verification process.
It doesn't mean that the old key will stop working but rather that it will not be possible to create new keys with this algorithm. You will be able to compile your app.

Thank you, Erle, I feel a little relieved.
In the future, it is possible that Google Protect will define my app as a virus because of the weakness of the key store?
Is it possible to repair the keystore and make its algorithm more powerful?

I guess no.
