Previously, when checking whether a CRT was revoked through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.
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.
Enable passing a number to "-v" in order to set the level of verbosity.
Print detailed test failure information at verbosity level 1 or higher.
Display summary messages at the verbosity level 2 or higher. Print
detailed test information at verbosity level 3 or higher, whether the
test failed or not. This enables a more readable output style that
includes detailed failure information when a failure occurs.
library/certs.c provides some hardcoded certificates that
are used e.g. by the test applications ssl_server2, ssl_client2
in case no certificates are provided on the command line.
The certificates used are from the tests/data_files folder
and have been updated in the latest commits. This commit
updates their copies in certs.c. It also adds comments
indicating the files from which the data is taken, in
order to ease update in the future.
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.
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.
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
