How to use the RSA encryption when receive RSA public key (S32K324 RTD4.4_2.0.1)

[Foxconn]

Hello NXP RD,

When I receive an RSA2048 public key from the Host, I need to store the public key in the HSE RAM space and use it for encryption. However, storing the key results in a 0x55A5A399 (parameter fail) error from the MU register when using the KeyElementSet function to import.

I found infomation that KeyElementSet does not support RSA keys.

How should I to implement this RSA function ?

Thanks

Best Regards
