Adjust the wording to permit multiple handles to a single key - closing
a handle does not necessarily release volatile memory associated with
the key, that only occurs when the last handle is closed.
- Describe the implementation defined behavior for opening multiple
keys, and provide a reference to the relevant section.
- Describe the use of INSUFFICENT_MEMORY error to indicate additional
implementation resource constaints.
- Clarify the distinction between DOES_NOT_EXIST and INVALID_HANDLE
error conditions.

Remove cryptography related files and a few utility header files that
are shared between Mbed TLS and Mbed Crypto. Mbed TLS will use an Mbed
Crypto sourced version of each of these header files in order to ease
the maintenance burden of both libraries, and to make it easier to keep
Mbed TLS and Mbed Crypto in sync.
As part of removing cryptography related files, tell Doxygen to source
information from the removed the headers, so that it will consider them
for inclusion within Doxygen output.
Later, as part of the Mbed TLS 3.0 (API breaking version), we'll
restructure the organization of the 3 libraries a bit, to move some
things out of Mbed Crypto that don't belong there.
Candidates of not belonging in Mbed Crypto, but are in libmbedcrypto.so
for legacy reasons:
- asn1.h
- asn1write.h
- base64.h
- memory_buffer_alloc.h
- platform.h
- platform_time.h
- platform_util.h
- threading.h
- timing.h
- version.h
To help the build system find the correct include files, paths starting
with "mbedtls/" or "psa/" must be used. Otherwise, you can run into
build failures like the following when building Mbed Crypto as a
submodule.
In file included from chachapoly.c:31:0:
../../include/mbedtls/chachapoly.h:43:10: fatal error: poly1305.h: No such file or directory

compilation terminated.
The function mbedtls_ssl_in_hdr_len() is supposed to return the length
of the record header of the current incoming record. With the advent
of the DTLS Connection ID, this length is only known at runtime and
hence so far needed to be derived from the internal in_iv pointer
pointing to the beginning of the payload of the current incooing
record.
By now, however, those uses of mbedtls_ssl_in_hdr_len() where the
presence of a CID would need to be detected have been removed
(specifically, ssl_parse_record_header() doesn't use it anymore
when checking that the current datagram is large enough to hold
the record header, including the CID), and it's sufficient to
statically return the default record header sizes of 5 / 13 Bytes
for TLS / DTLS.
The methods to import and generate a key in a secure element drivers
were written for an earlier version of the application-side interface.
Now that there is a psa_key_attributes_t structure that combines all
key metadata including its lifetime (location), type, size, policy and
extra type-specific data (domain parameters), pass that to drivers
instead of separate arguments for each piece of metadata. This makes
the interface less cluttered.
Update parameter names and descriptions to follow general conventions.
Document the public-key output on key generation more precisely.
Explain that it is optional in a driver, and when a driver would
implement it. Declare that it is optional in the core, too (which
means that a crypto core might not support drivers for secure elements
that do need this feature).
Update the implementation and the tests accordingly.
Register an existing key in a secure element.
Minimal implementation that doesn't call any driver method and just
lets the application declare whatever it wants.
Pass the key creation method (import/generate/derive/copy) to the
driver methods to allocate or validate a slot number. This allows
drivers to enforce policies such as "this key slot can only be used
for keys generated inside the secure element".
Test the behavior of the getter/setter functions.
Test that psa_get_key_slot_number() reports a slot number for a key in
a secure element, and doesn't report a slot number for a key that is
not in a secure element.
Test that psa_get_key_slot_number() reports the correct slot number
for a key in a secure element.
