Nir Sonnenschein 5ca6547b77 Renamed hmac_ctx to opad and removed null check.
this array is now part of the struct and not dynamically allocated
so it can't be null.

All the conflicts are concurrent additions where the order doesn't
matter. I put the code from feature-psa (key policy) before the code
from PR #13 (key lifetime).

2018-09-05 11:53:25 +03:00
Gilles Peskine 9ef733faa0 Implement hash functions
New header file crypto_struct.h. The main file crypto.sh declares
structures which are implementation-defined. These structures must be
defined in crypto_struct.h, which is included at the end so that the
structures can use types defined in crypto.h.

Implement psa_hash_start, psa_hash_update and psa_hash_final. This
should work for all hash algorithms supported by Mbed TLS, but has
only been smoke-tested for SHA-256, and only in the nominal case.
