Hi,
In the original thread, I understood 4096bit RSA key is supported on AM64x.
Does HW accelerator support 4096bit RSA key generation? Or software handles it?
Thanks and regards,
Koichiro Tashiro

Hello Koichiro,
Yes, up to RSA-4096 is supported by K3 crypto IP, where
x.509 certificate signed with user's root RSA private key is verified by ROM/TIFS SW in RoT secure boot flow.
Some reference from AM64x secure resource download portal
