All key types now have an encoding on 32 bits where the bottom 16 bits
are zero. Change to using 16 bits only.
Keep 32 bits for key types in storage, but move the significant
half-word from the top to the bottom.
Likewise, change EC curve and DH group families from 32 bits out of
which the top 8 and bottom 16 bits are zero, to 8 bits only.
Reorder psa_core_key_attributes_t to avoid padding.
Parametrize finite-field Diffie-Hellman key types with a DH group
identifier, in the same way elliptic curve keys are parametrized with
an EC curve identifier.
Define the DH groups from the TLS registry (these are the groups from
RFC 7919).
Replicate the macro definitions and the metadata tests from elliptic
curve identifiers to DH group identifiers.
Define PSA_DH_GROUP_CUSTOM as an implementation-specific extension for
which domain parameters are used to specify the group.
psa_status_t is currently a signed type where only non-negative values
are used, which makes things a bit awkward. For now, non-negative
values trigger an error. This code will need to be revised if we
switch to using negative values as error codes.
snprintf was only added in Visual Studio 2015. This adds support
for building using Visual Studio versions prior to 2015.
This implementation of snprintf has been taken from platform.c
Print the symbolic name corresponding to a numerical value.
Supported types: status values, algorithms, elliptic curves,
key types, key usage masks.
The program is partly generated from parsing psa/crypto.h with a few
hard-coded assumptions. This isn't ideal but it works and requires
little machinery.
