But I agree, the docs are a bit unclear here. Should be updated to reflect what actually is happening without making assumptions.
yea, was a bit confused cause in: https://github.com/OP-TEE/optee_docs/blame/master/architecture/secure_storage.rst#L362 did say "128 bits of k" after "k = SHA256(FEK);" :)
Thank you! Joakim

Hi, in https://github.com/OP-TEE/optee_docs/blame/master/architecture/secure_storage.rst#L344 SSK and TSK are 128-bit while each of them is a result of HMAC-SHA256 (should be 256-bit long each) What am I missing?
Thank you!
