Add the method SetHiResClockDisabled to IApplicationConfigurationBuilder
Fix the type of RejectedStore Created by the Builder to: CertificateStoreIdentifier
Add the method SetHiResClockDisabled to IApplicationConfigurationBuilder
Fix the type of RejectedStore Created by the Builder to: CertificateStoreIdentifier
A new configuration variable
<HttpsMutualTls>true</HttpsMutualTls>
enables the mutual TLS authentication support. The behavior of the TLS endpoint changes as the following:
HttpsMutualTls is true:
The server checks the trust on the certificate which is used by the client for TLS authentication. It must be a valid OPC UA application certificate which is trusted.
A client can still connect without providing a client certificate, but then it is only able to call discovery services.
In order to create a session, the client must use the same application certificate that was used for the TLS channel.
HttpsMutualTls is false:
- There is no application authentication. The server endpoint uses security None and there is no client application authentication.
Instead, only user authentication is used to secure the server, anonymous user authentication is disabled.
Discovery service calls are supported.

- Port support for ECC NIST/Brainpool profiles from prototyping_ecc branch
- Implement CertProvider to load certs per connection / profile
- Backward compatibility of configuration for existing apps
- SecurityConfiguration specifies app cert types for each profile
- Autodetect the ECC support for brainpool/nist based on platform (mac OS 10 doesn't support brainpool)
- ECC supported on net48 / net5.0 / net 6.0 / netstandard2.1
- ECC supported on windows / linux / macOS (brainpool not < macOS11)
- Self signed certs for each profile are created on start similar to RSA
- RSA only profiles are supported on .NET standard 2.0

- Add a light weight AddRejected certificate store method to `ICertificateStore` to ensure rejected cert history remains small and doesn't have a lot of overhead.
- Number of history certificates is configurable using a new `MaxRejectedCertificates` entry.
- Rejected certs are only saved to directory cert store, others do ignore the attempt
- Fix the caching of `CertificateValidator` and flag some `ÒpenStore` methods deprecated which do not support the caching. Fixes across the board to support the methodology. Basically `store.Close` keeps the cache, `store.Dispose` clears the cache, so recommendation is to use `var store = certStoreIdentifier.OpenStore(); try { ... }-- finally { store.Close }`
- Add a solution to provide fuzzer support for afl-fuzz and libfuzzer.
- Add fuzz targets for Binary, Json and Xml encoder and decoder fuzzing. For afl-fuzz and libfuzzer.
- Fix issues in encoders and decoders when unexpected exceptions are returned. The expectation is to return only ServiceResultException with BadDecodingError, BadEncodingError or BadEncodingLimitsExceeded.
- Add a tool to create Testcases.
- Add a tool to playback crashes and timeouts.
- Solution is extensible with common files to discover new fuzz targets by reflection. New fuzz projects can share many files with the first project.
- Breaking change: Fix how BinaryDecoder is used: Previously, calling close on the BinaryDecoder implicitly disposed the stream. Change behavior so that `using` pattern can be applied across the board.
* Added MaxChannelCount and detect and cleanup "stale" channels based on ChannelLifetime
* Add Environment.TickCount as time reference
* Set a socket backlog value to avoid socket open overflow
* Added a ChannelKeepAlive to signal when a session is still active
* Add options to console client to leak channels and run connect loop forever

- Issue fix: Currently when diagnostics is enabled in client calls, the string table in the response header is not updated when a service call is split into multiple service calls. In this case the stringtables from all calls must be appended and the index in the diagnosticinfo must be updated to match the updated string list.
- To reduce the number of 'null' DiagnosticInfo allocations, the decoders now try to return null instead of a default DiagnosticInfo. A new property ÌsNullDiagnosticInfo' can be used to check for unused DiagnosticInfo entries.
- The tests were slightly improved to use test set data from the generated TestData namespace, which contains also a historical node.
- All `ServerFixtureUtils.ValidateXXX` checks were updated to include the check for diagnosticInfos and the string tables to catch issues.
In some use cases (e.g. Kubernetes secrets) it would be beneficial to store the certificates, private keys, crl etc. in a flat directory instead of having a root which contains a hierarchy with certs/crl/private etc.
- Modify the `DirectoryCertificateStore` to allow it to use a flat structure by adding a special constructor.
- Add the configuration builder functions to allow to specify custom certificate stores for app/user/https.
- Add a test sample which shows how to use the 'flat store' with a custom cert store wrapper.
- By default, behavior of `DirectoryCertificateStore` is unchanged. Needs an external wrapper to expose the flat mode.
Currently, the validated certificates are stored in a dictionary for fast compare of the certificate validation when an application reconnects, until manually cleared by e.g. `ResetValidatedCertificates()`. After discussion it was decided to make this function an opt-in feature to avoid use cases where changes in the trusted store or CRL are not reflected in the list of validated certificates.
The runtime penalty of a full check can be avoided if needed with the 'Opt-In' by configuration or by application setting the property. After opt-in it is the application responsibility to clear the list of validated certificates if needed.
+++ Other cert validator improvements/fixes
- Setting the `ValidationOptions.SuppressRevocationStatusUnknown` on a trustlist (e.g. issuer) was ignored
- If another client/server connects with a chain, the whole chain is saved to the rejected store, not only the leaf certificate.
- Move the auditing flag to server internal
- Hook up new configuration setting to the Auditing node
- A Security Admin can change the Audit setting.
- Refactor audit events to be extensions in one class.
- enable auditing and diagnostics by default for higher test coverage.
- refactor dependency of some events to bindings, e.g. TcpServerChannel should not be used as reportevent parameter
- Add methods to support to Read/Browse multiple nodes in session and NodeCache.
- Add methods to find references of multiple nodes in NodeCache.
- By default the client fetches the operation limits from the server.
- Add operation limit object to client config, settings are overwritten by server limits if server limits are smaller.
- Split client service calls if operation limits are exceeded with an override of the SessionClient. All sync/async service calls are implemented, but not the servcie calls using the Begin/End pattern.
* smaller API changes for .368 and minor cleanup / uncritical bug fixes
* refactor GDS server lib to get rid of UA configuration dependency
* app config builder enhancements to simplify someuse cases
-- add a few default parameter to simplify fluent API
-- Rejected folder doesn't default to pki root
-- if the leaf pki folder is already provided, the default leaf folder is stil added (e.g. becomes own/own)
* certificate validator match were to return true even if no keyId/serial number was checked
* Directory store delete cert add retry if cert is still in use.
* enable reverse connect tests on macOS
* fixes CVE-2020-1045 (High) detected in microsoft.aspnetcore.http.2.1.1.nupkg mregen/UA-.NetStandardLibrary#114
- Add Operation limit parameter and fix server. Fixes#1363
- Add client/server test projects
- Add client and server fixture for test runs
- Server tests can test services without client connection
- Client tests can use common services to write tests which can run directly on server on via client server connection
- Increase code coverage > 50%
- Code coverage excludes the generated code
- Improve codecoverage local tests with report (see Tests/codecoverage scripts)
- Add a benchmark framework to client server tests
* Add no file configuration fluent API
* ensure secure settings are produced by default
* most if not all settings can be reached by .Set/.Add functions
* switched gds tests to use no file config (also good as starter)
