We had only allocated 40 bytes for printing into, but we wanted to print 46
bytes. Update the buffer to be 47 bytes, which is large enough to hold what
we want to print plus a terminating null byte.
Simplify the test case "PSA export a slot after a failed import of an
EC keypair": use an invalid private value for the specified curve. Now
the dependencies match the test data, so this fixes curves.pl.
Update some test data from the asymmetric_apis_coverage branch that
wasn't updated to the new format from the
psa-asymmetric-format-raw_private_key branch.
1. New test for testing bad order of hash function calls.
2. Removed test hash_update_bad_paths since it's test scenario
was moved to the new test.
3. Moved some scenarios from test hash_verify_bad_paths to
the new test.
1. Rename hash_bad_paths to hash_verify_bad_paths
2. Add test hash_update_bad_paths
3. Add test hash_finish_bad_paths
The different scenarios tested as part of hash_bad_paths are
moved to the relevant test.
This commit introduces variants test-ca_utf8.crt,
test-ca_printablestring.crt and test-ca_uppercase.crt
of tests/data_files/test-ca.crt which differ from
test-ca.crt in their choice of string encoding and
upper and lower case letters in the DN field. These
changes should be immaterial to the recovation check,
and three tests are added that crl.pem, which applies
to test-ca.crt, is also considered as applying to
test-ca_*.crt.
The test files were generated using PR #1641 which
- adds a build instruction for test-ca.crt to
tests/data_files/Makefile which allows easy
change of the subject DN.
- changes the default string format from `PrintableString`
to `UTF8String`.
Specifically:
- `test-ca_utf8.crt` was generated by running
`rm test-ca.crt && make test-ca.crt`
on PR #1641.
- `test-ca_uppercase.crt`, too, was generated by running
`rm test-ca.crt && make test-ca.crt`
on PR #1641, after modifying the subject DN line in the build
instruction for `test-ca.crt` in `tests/data_files/Makefile`.
- `test-ca_printable.crt` is a copy of `test-ca.crt`
because at the time of this commit, `PrintableString` is
still the default string format.
Previous commits have added or modified build instructions for
server1*, server2*, server5*, test-ca*, cli-rsa* in the Makefile
tests/data_files/Makefile, or the apps they invoke have been changed.
This commit regenerates those files to make sure they are in match with
the build instructions.

Previously, CSRs and CRTs from the server1* family in testa/data_files
were generated through OpenSSL. This commit changes the build instructions
to use Mbed TLS' example applications programs/x509/cert_write and
programs/x509/cert_req instead.
streamline the API for the test test_derive_invalid_generator_state: by removing
the key_data parameter.
This parameter is not important for test flow and can be hard-coded.
Add boundary test cases for private key validity for a short
Weierstrass curve (0 < d < n).
Remove obsolete test cases "valid key but wrong curve". With the new
format, the private key representation does not contain an encoding of
the curve.
In preparation for the import/export format change for private
elliptic curve keys from RFC 5915 to the raw secret value,
remove ASN.1-based sanity checks. For the raw secret value, most byte
strings of the correct length are valid (the details depend on the
curve), so as a sanity check, just check the length.
In preparation for the import/export format change for private
elliptic curve keys from RFC 5915 to the raw secret value, transform the
test data to the new format.
Tests will not pass until the implementation has been changed to the
new format and some test cases and test functions have been adjusted.
I used the script below to look for lines containing a
PSA_KEY_TYPE_ECC_KEYPAIR and change the first hex string in the
line with an ASN.1 header that looks like the beginning of an RFC 5915
ECPrivateKey. This always happens to be a private key input.
perl -a -F: -i -pe 'sub pad { local ($_) = @_; s/^00// if length == $digits + 2; die if length > $digits; sprintf("\"%0${digits}s\"", $_) } if ($F[0] !~ /\W/ && /:PSA_KEY_TYPE_ECC_KEYPAIR\( *PSA_ECC_CURVE_[A-Z_]+([0-9]+)/) {$digits = int(($1+7)/8)*2; s/"30(?:[0-7].|81..|82....)02010104(..)([0-9a-f]+)"/pad(substr($2, 0, hex($1)*2))/ie}' tests/suites/test_suite_psa_crypto.data
In the test function for export_public_key, don't just check the
length of the result. Compare the actual result to the expected
result.
Take an extra argument that allows using an export buffer that's
larger or smaller than needed. Zero is the size given by
PSA_KEY_EXPORT_MAX_SIZE.
Don't check the output of psa_get_key_information. That's useful in
import_export because it tests both import and export, but not in
import_export_public_key whose goal is only to test public key export.
This commit adjusts the existing test data but does not add new test
cases.
Key derivation test now uses an indirect way to test generator validity
as the direct way previously used isn't compatible with the PSA IPC
implementation. Additional bad path test for the generator added
to check basic bad-path scenarios.
Add comments noting that the maximum length of a MAC must fit in
PSA_ALG_MAC_TRUNCATION_MASK. Add a unit test that verifies that the
maximum MAC size fits.

Added buffer_size and response_size options for ssl-server2. Added appropriate tests.
Solving a conflict in tests/ssl-opt.sh: two set of tests were added at the
same place (just after large packets):
- restartable ECC tests (in this branch)
- server-side large packets (in development)
Resolution was to move the ECC tests after the newly added server large packet
ones.
This commit adds a test to tests/scripts/all.sh exercising an
ASan build of the default configuration with
MBEDTLS_PLATFORM_MEMORY enabled,
MBEDTLS_PLATFORM_CALLOC_MACRO set to std calloc
MBEDTLS_PLATFORM_FREE_MACRO set to std free
(This should functionally be indistinguishable from a default build)
Extend the mbedtls_mpi_is_prime_det test to check that it reports
the number as prime when testing rounds-1 rounds, then reports the
number as composite when testing the full number of rounds.
When using a primality testing function the tolerable error rate depends
on the scheme in question, the required security strength and wether it
is used for key generation or parameter validation. To support all use
cases we need more flexibility than what the old API provides.
Primality tests have to deal with different distribution when generating
primes and when validating primes.
These new tests are testing if mbedtls_mpi_is_prime() is working
properly in the latter setting.
The new tests involve pseudoprimes with maximum number of
non-witnesses. The non-witnesses were generated by printing them
from mpi_miller_rabin(). The pseudoprimes were generated by the
following function:
void gen_monier( mbedtls_mpi* res, int nbits )
{
mbedtls_mpi p_2x_plus_1, p_4x_plus_1, x, tmp;
mbedtls_mpi_init( &p_2x_plus_1 );
mbedtls_mpi_init( &p_4x_plus_1 );
mbedtls_mpi_init( &x ); mbedtls_mpi_init( &tmp );
do
{
mbedtls_mpi_gen_prime( &p_2x_plus_1, nbits >> 1, 0,
rnd_std_rand, NULL );
mbedtls_mpi_sub_int( &x, &p_2x_plus_1, 1 );
mbedtls_mpi_div_int( &x, &tmp, &x, 2 );
if( mbedtls_mpi_get_bit( &x, 0 ) == 0 )
continue;
mbedtls_mpi_mul_int( &p_4x_plus_1, &x, 4 );
mbedtls_mpi_add_int( &p_4x_plus_1, &p_4x_plus_1, 1 );
if( mbedtls_mpi_is_prime( &p_4x_plus_1, rnd_std_rand,
NULL ) == 0 )
break;
} while( 1 );
mbedtls_mpi_mul_mpi( res, &p_2x_plus_1, &p_4x_plus_1 );
}
Pass the nonce first, then the AD, then the input. This is the order
in which the data is processed and it's the order of the parameters to
the API functions.

Changes run-test-suites.pl to filter out directories, and select only files
as on OSX, test coverage tests create .dSYM directories which were being
accidentally selected to execute.
We don't need to disable ASLR, so don't try. If gdb tries but fails,
the test runs normally, but all.sh then trips up because it sees
`warning: Error disabling address space randomization: Operation not permitted`
and interprets it as an error that indicates a test failure.
Add signing tests with 528-bit and 520-bit RSA keys with SHA-512. These
selections of key and hash size should lead to an error returned, as
there is not enough room for our chosen minimum salt size of two bytes
less than the hash size. These test the boundary around an available
salt length of 0 or -1 bytes.
The RSA keys were generated with OpenSSL 1.1.1-pre8.

Since we wish to generate RSASSA-PSS signatures even when hashes are
relatively large for the chosen RSA key size, we need some tests. Our
main focus will be on 1024-bit keys and the couple key sizes larger than
it. For example, we test for a signature generated using a salt length
of 63 when a 1032-bit key is used. Other tests check the boundary
conditions around other key sizes. We want to make sure we don't use a
salt length larger than the hash length (because FIPS 186-4 requires
this). We also want to make sure we don't use a salt that is too small
(no smaller than 2 bytes away from the hash length).
Test RSASSA-PSS signatures with:
- 1024-bit key and SHA-512 (slen 62)
- 1032-bit key and SHA-512 (slen 63)
- 1040-bit key and SHA-512 (slen 64)
- 1048-bit key and SHA-512 (slen 64)
The tests also verify that we can properly verify the RSASSA-PSS
signatures we've generated.
We've manually verified that OpenSSL 1.1.1-pre8 can verify the
RSASSA-PSS signatures we've generated.

We've also added a new test that ensures we can properly validate a
RSASSA-PSS 1032-bit signature with SHA-512 generated by OpenSSL. This
has been added as the "RSASSA-PSS Verify OpenSSL-generated Signature
1032-bit w/SHA-512" test. The signature to verify was generated with the
following command line.
$ cat message.bin | openssl dgst -sha512 -sigopt rsa_padding_mode:pss -sigopt rsa_pss_saltlen:63 -sign rsa1032.pem > valid.bin
The RSA private keys used by these tests were generated with OpenSSL
1.1.1-pre8.

It should be valid to RSASSA-PSS sign a SHA-512 hash with a 1024-bit or
1032-bit RSA key, but with the salt size being always equal to the hash
size, this isn't possible: the key is too small.
To enable use of hashes that are relatively large compared to the key
size, allow reducing the salt size to no less than the hash size minus 2
bytes. We don't allow salt sizes smaller than the hash size minus 2
bytes because that too significantly changes the security guarantees the
library provides compared to the previous implementation which always
used a salt size equal to the hash size. The new calculated salt size
remains compliant with FIPS 186-4.
We also need to update the "hash too large" test, since we now reduce
the salt size when certain key sizes are used. We used to not support
1024-bit keys with SHA-512, but now we support this by reducing the salt
size to 62. Update the "hash too large" test to use a 1016-bit RSA key
with SHA-512, which still has too large of a hash because we will not
reduce the salt size further than 2 bytes shorter than the hash size.
The RSA private key used for the test was generated using "openssl
genrsa 1016" using OpenSSL 1.1.1-pre8.

We don't need to disable ASLR, so don't try. If gdb tries but fails,
the test runs normally, but all.sh then trips up because it sees
`warning: Error disabling address space randomization: Operation not permitted`
and interprets it as an error that indicates a test failure.
This commit fixes some missing size comparison. In
aead_encrypt_decrypt, aead_encrypt and aead_decrypt, the test code
would not have noticed if the library function had reported an output
length that was not the expected length.
ASSERT_COMPARE tests that the two buffers have the same size and
content. The intended use is to replace TEST_ASSERT( size1 == size2 )
followed by memcmp on the content. Keep using memcmp when comparing
two buffers that have the same size by construction.
This commit resolves a bug whereby some test cases failed on systems
where mbedtls_calloc returns NULL when the size of 0, because the test
case asserted `pointer != NULL` regardless of the size.
The new macro ASSERT_ALLOC allocates memory with mbedtls_calloc and
fails the test if the allocation fails. It outputs a null pointer if
the requested size is 0. It is meant to replace existing calls to
mbedtls_calloc.
Yotta is no longer supported by Mbed TLS, so has been removed. Specifically, the
following changes have been made:
* references to yotta have been removed from the main readme and build
instructions
* the yotta module directory and build script has been removed
* yotta has been removed from test scripts such as all.sh and check-names.sh
* yotta has been removed from other files that that referenced it such as the
doxyfile and the bn_mul.h header
* yotta specific configurations and references have been removed from config.h
Setting the dh_flag to 1 used to indicate that the caller requests safe
primes from mbedtls_mpi_gen_prime. We generalize the functionality to
make room for more flags in that parameter.
If some algorithms are excluded in the build, it's ok for the corresponding
macros not to give the correct results. Therefore the corresponding test cases
should depend on the implementation of the algorithm. For example, it's ok for
PSA_HASH_MAX_SIZE to be less than PSA_HASH_SIZE(PSA_ALG_SHA_512) if we build
without SHA-512 support, and we indeed do this. It's even ok for an
implementation to return 0 for PSA_ALG_IS_HASH(PSA_ALG_SHA_512) if it doesn't
support SHA-512; we return 1 anyway but the tests are less
implementation-specific if we don't enforce it.
This commit adds dependencies on symbols that don't exist in Mbed TLS,
for algorithms that Mbed TLS doesn't implement. These are:
MBEDTLS_SHA512_256 for SHA-512/256, MBEDTLS_SHA3_C for SHA-3,
MBEDTLS_DSA_C and MBEDTLS_DSA_DETERMINISTIC for DSA, and
MBEDTLS_ECP_DP_xxx_ENABLED for elliptic curves that have a PSA
encoding but are not supported in Mbed TLS.
For all key types, validate feature test macros (PSA_KEY_TYPE_IS_xxx).
For asymmetric keys (public key or key pair), validate the
corresponding public/pair type.
For ECC keys, validate GET_CURVE.
For all algorithms, validate feature test macros (PSA_ALG_IS_xxx).
For hash algorithms, validate the exact hash size, and validate
xxx_GET_HASH macros on dependent algorithms.
For MAC algorithms, validate the MAC size. For AEAD algorithms,
validate the tag size.
There is a separate test case for each HMAC algorithm, which is
necessary because each has its own MAC size. For other hash-dependent
algorithms, there is no interesting variation to test here, so only
one hash gets tested.
OFB and CFB are streaming modes. XTS is a not a cipher mode but it
doesn't use a separate padding step. This leaves only CBC as a block
cipher mode that needs a padding step.
Since CBC is the only mode that uses a separate padding step, and is
likely to remain the only mode in the future, encode the padding mode
directly in the algorithm constant, rather than building up an
algorithm value from a chaining mode and a padding mode. This greatly
simplifies the interface as well as some parts of the implementation.
