The Crypto driver is taken from MCAL package with version "nxp_S32K3xx-2.0.1_Aut03"

There are some potentials that can cause the HSE_SRV_RSP_GENERAL_ERROR as:

1. Use wrong key slot.

2. Use key has size is bigger than "Max key length in bits" of key slot.

Best regards,

Dan

Thank you @DanNguyenDuy , the cipher method refer to a RAM key slot and the issue is gone when we re-provide the RAM key.
