Is there a way to make my 1024 RSA key work in Adobe Animate 2020

Hi, 

Adobe Animate 2020 wants me to use a 2048 RSA key. But, if I do so, I won't be able te update my currents apps and will have to create new ones... 

It's really frustrating. 

I was wondering if there was a way to update my 1024 RSA key to 2048, or to make Animate 2020 accept the 1024. 

Thx
