Can you explain me how to do this? I have the same error.
For Android apps, it's not possible to change the certificates.
Workaround in Windows : change the Java path in the Windows Environment Variables > Path to an older Java version.
How do you change the path for mac?
Up to Java 1.8.0_74 works fine with RSA-1024 certificates, after upgrade to any higher version, don't work and the described error is shown packaging apps.
The only workaround for now is to downgrade Java.
Adobe, is there a way to Convert RSA-1024 P12 certificates to RSA-2048? because Google demands exactly the same certificate, can't be changed without create a new app in the store.
I got the same issue.
But I try to create a new RSA-1024 certificate(p12) it will run in normally.
So I guess the file format of certificate has been change?
Maybe some content had been removed in the new certificate
Unfortunately Animate doesn't allow to create RSA-1024 anymore, the selector combo is grayed out and pre-selected with RSA-2048 certificate, what procedure did you use to create a new RSA-1024 certificate?, it could be useful here to know different procedures to create certificates. Although, the big issue is that if you are updating an existing Android App, a new RSA-1024 certificate doesn't solve anything because that update must be packaged with exactly the same old certificate used to publish the first time.
