"HSE_SRV_RSP_GENERAL_ERROR" when request RSAES PKCSv1.5 encryption with RSA public key in RAM

[AquariusXo]

Hi Team

I tried request an RSA encryption action on HSE_B module in S32K312. But response an Error code from MU

Some details as below:

• Ver of HSE: HSE_0_2_1_0
• Algorithm: RSAES PKCSv1.5
• RSA public key stored in RAM and imported before request encryption.
• Data wait for encrypt is a HASH which calculated by SHA256.

Any hint to this error code?

Thank you.

Thank you @nxf78987 , the cipher method refer to a RAM key slot and the issue is gone when we re-provide the RAM key.

Hello @AquariusXo,

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,
