Previously, when checking whether a CRT was revoked through
one of the configured CRLs, the library would only consider
those CRLs whose `issuer` field binary-matches the `subject`
field of the CA that has issued the CRT in question. If those
fields were not binary equivalent, the corresponding CRL was
discarded.
This is not in line with RFC 5280, which demands that the
comparison should be format- and case-insensitive. For example:
- If the same string is once encoded as a `PrintableString` and
another time as a `UTF8String`, they should compare equal.
- If two strings differ only in their choice of upper and lower case
letters, they should compare equal.
This commit fixes this by using the dedicated x509_name_cmp()
function to compare the CRL issuer with the CA subject.
Fixes#1784.
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.
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.
This commit adds a command line option `md` to the example application
`programs/x509/cert_req` allowing to specify the hash algorithm to use
when signing the CSR.
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.
Return the condition compilation flags surrounding
`mbedtls_ecdh_compute_shared()`, `mbedtls_ecdh_gen_public()`,
`mbedtls_ecdsa_sign()` and `mbedtls_ecdsa_verify()` that were accidentally
removed in a previous merge.
Resolves#2163
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.
Skip all writing to the target buffer if its size is 0, since in this
case the pointer might be invalid and this would cause the calls to
memcpy and memset to have undefined behavior.
Change the import/export format of private elliptic curve keys from
RFC 5915 to the raw secret value. This commit updates the format
specification and the import code, but not the export code.
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.
