This is not useful to validate the implementation when importing
canonical input, which is the case for most import/export test cases,
but it helps validate the sanity checks themselves.
Implement sanity checks of exported public keys, using ASN.1 parsing.
Rewrite the sanity checks of key pairs using ASN.1 parsing, so as to
check more things with simpler code.
Move the code to perform sanity checks on the exported key from
generate_key to exercise_key. This way the sanity checks can be
performed after importing or deriving a key as well.
In addition to checking the exported key if its usage allows it, check
the exported public key if the key is asymmetric.
The last slot in the array was not freed due to an off-by-one error.
Amend the fill_slots test to serve as a non-regression test for this
issue: without this bug fix, it would cause a memory leak.
In psa_generator_import_key, if generating a DES or 3DES key, set the
parity bits.
Add tests for deriving a DES key. Also test deriving an AES key while
I'm at it.
In psa_generator_hkdf_read, return BAD_STATE if we're trying to
construct more output than the algorithm allows. This can't happen
through the API due to the capacity limit, but it could potentially
happen in an internal call.
Also add a test case that verifies that we can set up HKDF with its
maximum capacity and read up to the maximum capacity.
New key type PSA_KEY_TYPE_DERIVE. New usage flag PSA_KEY_USAGE_DERIVE.
New function psa_key_derivation.
No key derivation algorithm is implemented yet. The code may not
compile with -Wunused.
Write some unit test code for psa_key_derivation. Most of it cannot be
used yet due to the lack of a key derivation algorithm.
In asymmetric_encrypt_decrypt, use the buffer size advertized by the
library for the ciphertext, and the length of the plaintext for the
re-decrypted output.
Test the output length if known. Require it to be 0 on error for
encrypt/decrypt functions. If the output length is unknown, test at
least that it's within the buffer limits.
Add a label argument to all asymmetric encryption test functions
(currently empty in all tests, but that will change soon).
In asymmetric_encrypt and asymmetric_decrypt, with an empty label,
test with both a null pointer and a non-null pointer.
Although RSASSA-PSS defines its input as a message to be hashed, we
implement a sign-the-hash function. This function can take an input
which isn't a hash, so don't restrict the size of the input, any more
than Mbed TLS does.
Remove a redundant check that hash_length fits in unsigned int for the
sake of Mbed TLS RSA functions.
Test that PSS accepts inputs of various lengths. For PKCS#1 v1.5
signature in raw mode, test the maximum input length.
This required tweaking exercise_signature_key to use a payload size
for the signature based on the algorithm, since our implementation of
PSS requires that the input size matches the hash size. This would
also be the case for PKCS#1 v1.5 with a specified hash.
* No test depends on MBEDTLS_PK_C except via MBEDTLS_PK_PARSE_C, so
remove MBEDTLS_PK_C and keep only MBEDTLS_PK_PARSE_C.
* Add MBEDTLS_PK_WRITE_C for pk export tests.
* Add MBEDTLS_GENPRIME for RSA key generation tests.
* Add dependencies to AEAD tests.
* Add missing dependencies to many RSA tests.
* Add a test for decryption with invalid padding.
* Add a test for encryption with input too large.
* In negative tests, pass input whose length matches the key length,
unless that's what the test is about.
Make function names for multipart operations more consistent (cipher
edition).
Rename symmetric cipher multipart operation functions so that they all
start with psa_cipher_:
* psa_encrypt_setup -> psa_cipher_encrypt_setup
* psa_decrypt_setup -> psa_cipher_decrypt_setup
* psa_encrypt_set_iv -> psa_cipher_set_iv
* psa_encrypt_generate_iv -> psa_cipher_generate_iv
Change most asymmetric_verify to use public keys (they were all using
key pairs before). Keep one test with an RSA key pair and one with an
EC key pair.
Revise the test function asymmetric_encrypt_fail into
asymmetric_encrypt and use it for positive tests as well. Get the
expected output length from PSA_ASYMMETRIC_ENCRYPT_OUTPUT_SIZE. Check
the actual output length against test data.
Add positive test cases for encryption: one with an RSA public
key (this is the only test for encryption with a public key rather
than a key pair) and one with a key pair.
Make function names for multipart operations more consistent (MAC
setup edition).
Split psa_mac_setup into two functions psa_mac_sign_setup and
psa_mac_verify_setup. These functions behave identically except that
they require different usage flags on the key. The goal of the split
is to enforce the key policy during setup rather than at the end of
the operation (which was a bit of a hack).
In psa_mac_sign_finish and psa_mac_verify_finish, if the operation is
of the wrong type, abort the operation before returning BAD_STATE.
No common signature algorithm uses a salt (RSA-PKCS#1v1.5, RSA-PSS,
DSA, ECDSA, EdDSA). We don't even take an IV for MAC whereas MAC
algorithms with IV are uncommon but heard of. So remove the salt
parameter from psa_asymmetric_sign and psa_asymmetric_verify.
Add tests of key policy checks for MAC, cipher, AEAD, asymmetric
encryption and asymmetric signature. For each category, test
with/without the requisite usage flag in each direction, and test
algorithm mismatch.
At this point it fixes memory leaks as well. These memory leaks are the
fault of the 'psa_cipher_finish()' function and the calls fixed in this
commit (among with many others in the test suite) will become obsolete
after fixing 'psa_cipher_finish()'.
Add required includes in tests and psa_crypto.c file in order to be able to compilef for the SPM solution.
Some functions needed to be deprecated from psa_crypto.c since they already implemented in the SPM.
Use PSA_BLOCK_CIPHER_BLOCK_SIZE() macro to get the cipher block size instead of accessing the operation struct
additionally, for SPM case, the 'block_size' member is not a member in the operation struct
