* Replace SessionStateEncoder with IEncodeable on session/subscription models
- Source-gen [DataType]/[DataTypeField] on: MonitoredItemOptions, MonitoredItemState,
SubscriptionOptions, SubscriptionState (auto-generated Encode/Decode/IsEqual/Clone)
- Manual IEncodeable on: SessionOptions, SessionState, SessionConfiguration
(ConfiguredEndpoint and IUserIdentity require manual encoding)
- Delete SessionStateEncoder.cs (488 lines removed)
- Remove [DataContract]/[DataMember]/[KnownType]/[CollectionDataContract] attributes
- Remove JsonSerializerContext classes
- Change init -> set, byte[] -> ByteString, DateTime -> DateTimeUtc
- MonitoredItems: ArrayOf<MonitoredItemState> with StructureHandling.Inline
- Subscriptions: ArrayOf<SubscriptionState>
* Source generator: support partial init properties with backing fields
Add IsInitOnly detection to the [DataType] source generator so that
partial properties with init-only setters can be used in IEncodeable types.
For each init-only partial property, the generator:
- Emits a private backing field (__PropertyName)
- Emits the partial property implementation (get => __field; init => __field = value)
- Uses the backing field in Decode() instead of the property
- Skips simple init-only fields in Clone() (record 'with' already copies them)
Detection uses both IPropertySymbol.SetMethod.IsInitOnly and syntax-tree
fallback (SyntaxKind.InitAccessorDeclaration) for partial definitions.
* docs: add partial init properties and session state migration sections
- SourceGeneratedDataTypes.md: new 'Partial Init Properties' section
documenting backing field generation for init-only partial properties
- MigrationGuide.md: new 'Session State Persistence' section covering
* merged security changes
* Tailor SecurityPolicyUri for format expected in s_securityPolicyUriToInfo
* Enhance security policy handling and key computation logic
* Merge SecurityEnhancements.
* Add support for SessionTransferToken. Removed obsolete SoftwareCertificate code.
* Fix NonceLength for None.
* Add support for RSA_DH, more fixes from IOP testings.
* Finish implementation of SecureChannelEnhancements.
* Rename EccUtils.cs to CryptoUtils.cs
* Address feedback from reviewers.
* Fix CoPilot flagged spelling errors.
* Rename EccUtils to CryptoUtils
* Update version from 1.5.378-preview to 1.5.378
* Fix unit tests.
* Allow SignatureData.Algorithm to be NULL or Empty.
* Fix issue with BrainPool_p256r1_ChaChaPoly
* Fix RSA_DH_AesGcm
* Fix OSC/padding by deriving HMAC keys, tightening symmetric size math, and correcting ECC_brainpoolP384r1/Basic128Rsa15 IV, signature, padding, and nonce parameters.
* Policies without asymmetric encryption (ECC) return the plaintext when encrypting user tokens; this prevents null payloads from causing BadIdentityTokenInvalid.
* Reserve outer CBC padding for avoiding SymetricEncryptAndSign->AddPadding to overwrite next fields (signature)
* Nonce stored as byte array in SessionConfiguration; Sesion snapshot restores ServerNonce and reconstructs ECC ephemeral key Nonce from bytes and policy
* Added _AesGcm and _ChaChaPoly variants to BuildSupportedSecurityPolicies() for all six ECC certificate types (nistP256, nistP384, brainpoolP256r1, brainpoolP384r1, curve25519, curve448) to SecurityConfiguration. Added Sign and SignAndEncrypt endpoints for the four ECC AesGcm/ChaChaPoly policy pairs (nistP256, nistP384, brainpoolP256r1, brainpoolP384r1) to ServerFixture.
* make ephemeralKeyPolicyUri nullable
* GenerateSecret also for NET7 and NET8
* Adjust Basic128Rsa15 policy properties for backword compatibility
* Exclude unsuported AEAD policies from .NET Framework client tests
* Addapt to new changes (still build fail)
* Addapt code to make it compile
* Fixed failing build on net48 (by ignoring potential null ref which is not reported on other newer targets)
* Preserve the certificate reference in Clone() so copied handlers can still sign
* Remove extra code and addapt to existing master configuration settings
* Filter *_AesGcm and *_ChaChaPoly security policies based on actual runtime support, so unsupported AEAD policies are not advertised or selected on older frameworks
* Expand ECC/RSA policy test coverage and keep Basic128Rsa15 nonce length backward-compatible
* Fix ReconnectSessionOnAlternateChannel _AES and _ChaCha policies
* Fixed IgnoreIfPolicyNotAdvertised so it now fetches endpoints on-demand (instead of relying on Endpoints being preloaded by earlier tests), which avoids false ignores when running tests directlyy
* Merge with commit 5e627f2ca1 from secure-channel-enhancements-2025-11 branch
* minor log mesatge formating
* Fix ClientLockoutTests
* Add ServerFixture policies upfront only if framework and runtime capability supports them
* A few cosmetic/config changes as review sugested
* Moved the session/security handling from StandardServer into a dedicated helper
* use X509IdentityTokenHandler from secure-channel-enhancements-2025-11
* Removed unused Opc.Ua.Types.UnitTests.csproj
* test(client): fix Basic128Rsa15 reconnect token-policy coverage
Advertise an explicit Basic128Rsa15 user token policy in the test fixture and tighten the reconnect test preconditions for non-advertised policies.
* test(client): fix session nonce persistence test helpers
Replace the generic reflection helpers in SessionTests with explicit client/server nonce accessors that match the actual field types.
Add a short Session comment to explain why client and server nonces currently use different representations.
* Merge branch 'master' into secure-channel-enhancements-2025-11-merge5
Merge with latest master and fix conflicts.
* Removed unused Opc.Ua.Types.UnitTests.csproj
* test(client): fix Basic128Rsa15 reconnect token-policy coverage

- 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
