AES in CTR Mode: IV not saved to IOC file

[zeboss49]

Hello,

I'm facing an issue in CubeMX with the AES IV in CTR Mode

The IV is not saved in the IOC file and is discarded from the generated code, replaced with a full 0 value.

The AES content inside the IOC file:

AES.Algorithm=CRYP_AES_CTR
AES.DataType=CRYP_DATATYPE_8B
AES.DataWidthUnit=CRYP_DATAWIDTHUNIT_BYTE
AES.IPParameters=KeySize,DataType,DataWidthUnit,pKey,Algorithm
AES.KeySize=CRYP_KEYSIZE_256B
AES.pKey=-------- -------- -------- -------- -------- -------- -------- --------

MCU: STM32F423VHT

CubeMX: Latest version 6.16.1

AES Settings

Algorithm
Data encryption type AES CTR
Parameters
Data type 8b(byte swapping)
KeySize 256b
Encryption/Decryption key -------- -------- -------- -------- -------- -------- -------- --------
Initialization vector E467824C 805348FF 4CE1DF70 566ED4A9
Data width unit Byte
Key and IV configuration skip Always

Hello,

thanks for the change :)
You're right, the previous title was a rubbish.

Hello @zeboss49 ,

The behavior described was not reproduced by my side, knowing that I am using STM32CubeMX 6.16.1.

I will be waiting for your feedback.

Thanks.

Hello,

the issue no longer exists with CubeMX 6.16.1.

I upgraded recently and did not check the issue after upgrading.

Sorry for the inconvenience.

Thanks
