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.
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.
Explicitly state that calling abort is safe after initializing to
zero.
Explicitly state that calling abort on an inactive operation is safe,
and replace "active" by "initialized" in the description of the
parameter.
Get rid of the recommendation for implementers to try to handle
uninitialized structures safely. It's good advice in principle but
cannot be achieved in a robust way and the wording was confusing.
* 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.
We failed check-names.sh due to using a define which wasn't described or
defined anywhere. Even though we won't realistically enable
MBEDTLS_PSA_CRYPTO_SPM via the configuration system (and will do it from
PSA Crypto SPM tooling instead), add a description of the configuration to
config.h as good practice. Exclude MBEDTLS_PSA_CRYPTO_SPM from the "full"
configuration as well.
We failed all.sh on the "test: doxygen markup outside doxygen blocks" due
to doxygen markup being outside a Doxygen block. Add an extra `*` to the
psa_get_key_from_slot comment to denote the comment as a Doxygen comment.
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
Use if-else-if chains rather than switch because many blocks apply to
a class of algoritmhs rather than a single algorithm or a fixed set
of algorithms.
Call abort on more error paths that were missed earlier.
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()'.
Reorganize error handling code in psa_mac_finish_internal,
psa_mac_sign_finish and psa_mac_verify finish to ensure that:
* psa_mac_abort() is always called, on all success and error paths.
* psa_mac_finish places a safe value in the output parameters on
all error paths, even if abort fails.
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.
In mbedtls_rsa_rsaes_oaep_encrypt and
mbedtls_rsa_rsaes_pkcs1_v15_encrypt, if the input length is 0 (which
is unusual and mostly useless, but permitted) then it is fine for the
input pointer to be NULL. Don't return an error in this case.
When `input` is NULL, `memcpy( p, input, ilen )` has undefined
behavior even if `ilen` is zero. So skip the `memcpy` call in this
case. Likewise, in `mbedtls_rsa_rsaes_oaep_decrypt` and
`mbedtls_rsa_rsaes_pkcs1_v15_decrypt`, skip the `memcpy` call if
`*olen` is zero.
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.
The RSA module uses unsigned int for hash_length. The PSA Crypto API
uses size_t for hash_length. Cast hash_length to unsigned int when
passed to the hash module.
In psa_hash_finish and psa_mac_finish_internal, set the fallback
output length (which is reported on error) to the output buffer size,
not to the _expected_ buffer size which could be larger.
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
