macro definition for encrypt API

[ShinjiOhishi]

About encrypt a data using the following API on LPC55S69.

• psa_cipher_generate_iv
• psa_cipher_update
• psa_cipher_finish

The following macro definition is defined in the API specification. https://developer.arm.com/documentation/ihi0086/latest/

• PSA_CIPHER_IV_LENGTH
• PSA_CIPHER_UPDATE_OUTPUT_SIZE
• PSA_CIPHER_UPDATE_OUTPUT_MAX_SIZE
• PSA_CIPHER_FINISH_OUTPUT_SIZE
• PSA_CIPHER_FINISH_OUTPUT_MAX_SIZE

I have mbedtls enabled and tried to build the SDK, but crypto_sizes.h doesn't have these macro definitions.
Why is no define?

Hi, Felipe Garcia.
Thank you for answering.

Hi Shinji,

According to the same document you are referring those macros were added in 1.0 beta 3 version. You can see this in the C.1.2 Changes between 1.0 beta 3 and 1.0.0 section of the document.

Our latest SDK is using Platform Security Architecture APIs Version 1.0 so these new macros are still not reflected in our drivers.

Best regards,

Felipe
