Gilles Peskine	058e0b9963	Avoid empty unions ... When no algorithms are present in a category (e.g. no AEAD algorithm), the union in the corresponding operation structure was empty, which is not valid C. Add a dummy field to avoid this.	2018-09-05 11:53:26 +03:00
Gilles Peskine	7698bcf338	Basic interface for key policies ... Get/set the policy of a key slot. Opaque structure for key policies and field access functions.	2018-09-05 11:53:25 +03:00
Gilles Peskine	3b555710e2	Prototypes for AEAD functions ... This is still tentative.	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.	2018-09-05 11:53:25 +03:00
