Gilles Peskine 05c900b576 Forbid keys of size 0 
Keys of size 0 generally don't make sense: a key is supposed to be
secret. There is one edge case which is "raw data" keys, which are
useful to store non-key objects in the same storage location as keys.
However those are also problematic because they involve a zero-length
buffer. Manipulating zero-length buffers in C requires special cases
with functions like malloc() and memcpy(). Additionally, 0 as a key
size already has a meaning "unspecified", which does not always
overlap seamlessly with the meaning "0".

Therefore, forbid keys of size 0. No implementation may accept them.
 2019-09-12 18:29:43 +02:00
Gilles Peskine a170d927dd Clarify how key creation functions use attributes and what 0 means 
Clarify how key creation functions use attributes. Explain the meaning
of attribute values, espcially what 0 means in each field where it has
a special meaning. Explain what an algorithm usage policy can be (an
algorithm, a wildcard with ANY_HASH, or 0).

Adrian L. Shaw 11638b99a0 Added PSA_ERROR_INSUFFICIENT_MEMORY to psa_export_public_key

 2019-09-04 11:31:14 +01:00
Adrian L. Shaw 7f1863c905 Add PSA_ERROR_INSUFFICIENT_MEMORY to psa_export_key 
It may be possible that the implementation runs out of
memory when exporting a key from storage or a secure
element. For example, it may not be possible to directly
move the data from storage to the caller, so the implementation
will have to buffer the material temporarily (an issue if dynamic
memory allocation scheme is used). For a large key
this is more likely to return.
 2019-09-04 11:31:14 +01:00
Adrian L. Shaw 15731c1422 Added PSA_ERROR_STORAGE_FAILURE to psa_export_key 
It may be possible that an implementation does not
fetch key material until a command like
this is called and such an error may occur if an
off-chip secure storage dependency may have been wiped.
 2019-09-04 11:31:14 +01:00
Adrian L. Shaw 23c006f45e Added missing return codes to get_key_attributes 
Note that PSA_ERROR_NOT_PERMITTED is not included

attributes

Adrian L. Shaw e926e7370f Removed PSA_DOES_NOT_EXIST from psa_export_public_key

Adrian L. Shaw 742084ea25 Removed PSA_ERROR_DOES_NOT_EXIST from psa_export_key 
If the key doesn't exist by the time this call is made
then the handle is invalid,
which means that PSA_ERROR_INVALID_HANDLE should be
returned rather than "does not exist"
