STSAFE-A110 StSafeA_PutAttribute() and StSafeA_VerifyPassword() fail to set/verify password

[Michael98006]

I was trying to test the capability of the STSAFE-A110 chip to store and verify a password, but it didn't work.

StSafeA_PutAttribute() returned STSAFEA_UNSATISFIED_ACCESS_CONDITION.

StSafeA_VerifyPassword() returned STSAFEA_ENTRY_NOT_FOUND.

I'm not sure what any of this means. When I call other functions, like StSafeA_GenerateSignature() or StSafeA_VerifyMessageSignature(), they work just fine. Why would StSafeA_PutAttribute() and StSafeA_VerifyPassword() not work?

Here's my code:

char* passwordStr = "banana101";  // Same as in the OpenSSL example
int32_t statusCode;
StSafeA_VerifyPasswordBuffer_t commandResult;

// This call returns STSAFEA_UNSATISFIED_ACCESS_CONDITION instead of STSAFEA_OK
statusCode = StSafeA_PutAttribute(gStsafeHandle, STSAFEA_TAG_PASSWORD_SLOT, (uint8_t*)passwordStr, strlen(passwordStr), STSAFEA_MAC_NONE);

// This call returns STSAFEA_ENTRY_NOT_FOUND instead of STSAFEA_OK
statusCode = StSafeA_VerifyPassword(gStsafeHandle, (uint8_t*)passwordStr, &commandResult, STSAFEA_MAC_NONE);

Hi @Michael98006 ,

Thanks for you interest to STSAFE-A110 solution.

The password use case is only available on personalized part.

Therefore you need to contact your local ST team to make a personalization with password enabled.

You can't activate it on evaluation's part.

Best Regards,
