* Log client certificate type and length
It appears that most client certificates are RSA certs, but we should
make sure that is indeed the case. Print out the strength of the cert
if it is RSA.
Also adds supports for TLS 1.3 and print out the supported cipher suites.
* Add a comment about zero length certificate
* Make length of non-RSA keys -1
* Don't use TLS 1.3 if JDK SSL provider is used
* Use CA cert in tests
Our tests were using a self-signed cert created by a netty utility.
That cert is not CA, and cannot be used with newer JDK versions
(starting from u242 with Ubuntu openjdk).
Now we generate a unsafe cert for tests. The new cert,
SelfSignedCaCertificate, needs to be made test-only.
To do so we need to refactor both prober and proxy.
* Upgradle JUnit to 4.13
Removed third_party/junit folder and all usage of the
JunitBackPort class. As a result, third_party is no
longer a Gradle subproject.
Minor code changes were needed to work around an
error-prone pattern: multiple statement in assertThrows'
runnable lambda.
Also third_party/activation and third_party/jsch. These
dependencies are loaded from remote maven repo. The local
copies are not in use.
* Consolidate certificate supplier module
Both the proxy and the proxy needs certificate suppliers. The PR
consolidates the module that providings those bindings to a shared
module and switched the proxy to use that module. The prober currently
uses P12 file to store its certificates. I am debating keeping that
supplier ro converting them to PEM files for simplicity.
* Rename mode enum values to be more descriptive
* Update annotation names to be more descriptive
The promise should be set outside the try block because if we want
warning only, we still want the promise to be set even if the
clientCertificate.checkValidity() throws an error.
Client SSL handler already performs the necessary validation. Only tests are
added.
Server SSL handler does not currently check for the validity period of
the client certificate as the insecure trust manager is used. This PR
added the check but does not actually terminate the connection yet. It
will log the expired certificates so that we can contact the registrars
to update them.
Once we are certain that all certificates are updated, we can turn off
dryrun mode.
We should also consider checking if the certificate has too long a
validity period as it defeats the purpose of using regularly updated
certificates to deprecate insecure cipher suites.
The prober now uses the common SSL initializer in the networking
subproject.
Also changed both initializers to take an ImmutableList of certificates
other than an array of those, for better immutability.
I have no idea where these lockfile changes are coming from. They seem
to be pure noise as far as code review is concerned.
