Hi Ruchika,

We definitely want to add these entry points when we find the time. I can't speak as to when we'll find the time.

Best regards,

Hi All,

 

The PSA driver interface guide describes the driver entry points for key derivation. However the implementation seems to be missing from the psa crypto core layer.

 

Can you help update if this is something which is being worked on ?  I see a lot of tickets open related for key derivation interface dating back in 2022. Are these still relevant ?

 

Regards,

Ruchika
