Warning: The signer's certificate is self-signed. The SHA1 algorithm specified for the -digestalg option is considered a security risk. This algorithm will be disabled in a future update. The SHA1withRSA algorithm specified for the -sigalg option is considered a security risk. This algorithm will be disabled in a future update.

I'm trying to make production build for android using my my-release-key.keystore file with this command

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.keystore app.aab aliasName

and it shows me the warning, so, how can I resolve this warning and which algorithm do I use instead of it ??

Thanks in advance.

I resolved this warning using SHA2 algorithm

sudo jarsigner -verbose -sigalg SHA256withRSA -digestalg SHA-256 -keystore my-release-key.keystore /Volumes/Development/my_project/git_repo/platforms/android/app/build/outputs/apk/release/app-release-unsigned.apk aliasName
