f9fbc38e66 Declare key id 0 as invalid
In keeping with other integral types, declare 0 to be an invalid key
identifier.

Documented, implemented and tested.

f9666595e1 Implement and test the new key identifier range
Only allow creating keys in the application (user) range. Allow
opening keys in the implementation (vendor) range as well.

Compared with what the implementation allowed, which was undocumented:
0 is now allowed; values from 0x40000000 to 0xfffeffff are now
forbidden.

225010fdf7 Remove lifetime parameter from psa_open_key
Change the scope of key identifiers to be global, rather than
per lifetime. As a result, you now need to specify the lifetime of a
key only when creating it.

e56e878207 Remove extra parameter from psa_generate_key
Read extra data from the domain parameters in the attribute structure
instead of taking an argument on the function call.

Implement this for RSA key generation, where the public exponent can
be set as a domain parameter.

Add tests that generate RSA keys with various public exponents.

772c8b16b4 psa_get_domain_parameters: for RSA, if e=65537, output an empty string 2019-04-26 17:37:21 +02:00

b699f07af0 Switch psa_{get,set}_domain_parameters to attributes
Change psa_get_domain_parameters() and psa_set_domain_parameters() to
access a psa_key_attributes_t structure rather than a key handle.

In psa_get_key_attributes(), treat the RSA public exponent as a domain
parameter and read it out. This is in preparation for removing the
`extra` parameter of psa_generate_key() and setting the RSA public
exponent for key generation via domain parameters.

In this commit, the default public exponent 65537 is not treated
specially, which allows us to verify that test code that should be
calling psa_reset_key_attributes() after retrieving the attributes of
an RSA key is doing so properly (if it wasn't, there would be a memory
leak), even if the test data happens to use an RSA key with the
default public exponent.

3a4f1f8e46 Set the key size as an attribute
Instead of passing a separate parameter for the key size to
psa_generate_key and psa_generator_import_key, set it through the
attributes, like the key type and other metadata.

87a5e565f4 Rename functions that inject key material to an allocated handle
This commit starts a migration to a new interface for key creation.
Today, the application allocates a handle, then fills its metadata,
and finally injects key material. The new interface fills metadata
into a temporary structure, and a handle is allocated at the same time
it gets filled with both metadata and key material.

This commit was obtained by moving the declaration of the old-style
functions to crypto_extra.h and renaming them with the to_handle
suffix, adding declarations for the new-style functions in crypto.h
under their new name, and running

    perl -i -pe 's/\bpsa_(import|copy|generator_import|generate)_key\b/$&_to_handle/g' library/*.c tests/suites/*.function programs/psa/*.c
    perl -i -pe 's/\bpsa_get_key_lifetime\b/$&_from_handle/g' library/*.c tests/suites/*.function programs/psa/*.c

Many functions that are specific to the old interface, and which will
not remain under the same name with the new interface, are still in
crypto.h for now.

All functional tests should still pass. The documentation may have
some broken links.

3135184cfc Merge remote-tracking branch 'upstream-crypto/development' into psa-api-beta2-merge-development
Merge the Mbed Crypto development branch a little after
mbedcrypto-1.0.0 into the PSA Crypto API 1.0 beta branch a little
after beta 2.

Summary of merge conflicts:

* Some features (psa_copy_key, public key format without
  SubjectPublicKeyInfo wrapping) went into both sides, but with a few
  improvements on the implementation side. For those, take the
  implementation side.
* The key derivation API changed considerably on the API side. This
  merge commit generally goes with the updated API except in the tests
  where it keeps some aspects of the implementation.

Due to the divergence between the two branches on key derivation and
key agreement, test_suite_psa_crypto does not compile. This will be
resolved in subsequent commits.

c70a3c76bf Merge remote-tracking branch 'tls/development' into development
Resolve conflicts actions:
 - Reject path changes to config.h
 - Reject submodule-related changes in build scripts (Makefile,
   CMakeLists.txt)
 - Add oid test suite to list of tests in tests/CMakeLists.txt,
   rejecting any test filtering related changes (which TLS uses to avoid
   duplicating crypto tests)
 - Add legacy ECDH test to all.sh without including
   all.sh tests that depend on SSL

57f4d9e4fe Update crypto submodule to test with private headers
Update the crypto submodule to the top of the Mbed Crypto development
branch. This brings in a version of Mbed Crypto that enables building
Mbed Crypto tests that depend on private headers, like
'psa_crypto_invasive.h'.

This also requires updating our config.h to include new configuration
options added to Mbed Crypto. MBEDTLS_PSA_ITS_FILE_C replaces
MBEDTLS_PSA_CRYPTO_STORAGE_FILE_C and MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C.
MBEDTLS_PSA_INJECT_ENTROPY replaces MBEDTLS_PSA_HAS_ITS_IO.

5e80d91dbf Remove psa_crypto_storage_backend.h
Since there is now a single storage backend, we don't need a backend
interface. Make the functions that were declared in
psa_crypto_storage_backend.h and are now both defined and used in
psa_crypto_storage.c static, except for psa_is_key_present_in_storage
which is used by the gray-box tests and is now declared in
psa_crypto_storage.h.

088b77f39c Merge psa_crypto_storage_its into psa_crypto_storage
Since the ITS API has stabilized and we don't plan to make use of more

e435f23019 Remove psa_crypto_storage_file
Now that we have ITS over files, we no longer need a direct backend
for key storage over files. Remove psa_crypto_storage_file and its
tests.

Switch MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C and MBEDTLS_PSA_ITS_FILE_C on
by default. This preserves functionality and test coverage in the
default configuration, but forgets any key previously stored using the
file backend.
