Updated System.IdentityModel.Tokens.Jwt from 6.10.2 to 6.34.0.

Release notes

Sourced from System.IdentityModel.Tokens.Jwt's releases.

6.34.0

Security fixes

See https://aka.ms/IdentityModel/Jan2024/zip and https://aka.ms/IdentityModel/Jan2024/jku for details.

6.33.0

Bug Fixes:

  • Clean up log messages. See #​2339 for details.
  • Decouple JsonElements from JsonDocument, which causes issues in multi-threaded environments. See #​2340 for details.

6.32.3

6.32.2

6.32.2

Bug fixes:

  • Underlying JsonDocument is never disposed, causing high latency in large scale services. See #​2258 for details.

6.32.1

6.32.0

New features:

  • Adding an AAD specific signing key issuer validator. See issue #​2134 for details.
  • Better support for WsFederation (#​2100)

Bug fixes

  • Address perf regression introduced in 6.31.0 (#​2131)

6.31.0

This release contains work from the following PRs and commits:

6.30.1

This release contains work from the following PRs:

  • Modified token validation to be async throughout the call graph #​2075
  • Enforce key sizes when creating HMAC #​2072
  • Fix AotCompatibilityTests #​2066
  • Use up-to-date "now", in case take long time to get Metadata #​2063

This release addresses #​1743 and, as such, going forward if the SymmetricKey is smaller than the required size for HMAC IdentityModel will throw an ArgumentOutOfRangeException which is the same exception when the SymmetricKey is smaller than the minimum key size for encryption.

6.30.0

Beginning in release 6.28.0 the library stopped throwing SecurityTokenUnableToValidateException. This version (6.30.0) marks the exception type as obsolete to make this change more discoverable. Not including it in the release notes explicitly for 6.28.0 was a mistake. This exception type will be removed completely in the next few months as the team moves towards a major version bump. More information on how to replace the usage going forward can be found here: https://aka.ms/SecurityTokenUnableToValidateException

#​1949

6.23.1

A simple 'dot' release to fix an issue where JsonWebTokenHandler virtual CreateClaimsIdentity was not called.
AzureAD/azure-activedirectory-identitymodel-extensions-for-dotnet#1940

6.23.0

#​1934 JsonWebToken and JsonWebTokenHandler use System.Text.Json for JSON parsing for targets Net61+.
String splits have been removed and much of the duplicated string copying and processing has been removed resulting in a 20-25% performance increase.

#​1924 This delegate will be called just before a token has the SignatureValidated. This allows for preprocessing of the token prior to signature validation. This is currently only used by the JsonWebTokenHandler.

6.22.1

New Features:

Microsoft.IdentityModel has two assemblies to manipulate JWT tokens:

System.IdentityModel.Tokens.Jwt, which is the legacy assembly. It defines JwtSecurityTokenHandler class to manipulate JWT tokens.
Microsoft.IdentityModel.JsonWebTokens, which defines the JsonWebToken class and JsonWebTokenHandler, more modern, and more efficient.
When using JwtSecurityTokenHandler, the short named claims (oid, tid), used to be transformed into the long named claims (with a namespace). With JsonWebTokenHandler this is no longer the case, but when you migrate your application from using JwtSecurityTokenHandler to JsonWebTokenHandler (or use a framework that does), you will only get original claims sent by the IdP. This is more efficient, and occupies less space, but might trigger a lot of changes in your application. In order to make it easier for people to migrate without changing their app too much, this release offers extensibility to re-add the claims mapping.

Bug Fixes:

(#​1933) Wrong parameter order when calling ValidateLifetimeAndIssuerAfterSignatureNotValidatedJwt

6.22.0

New Features:

Unmasked non-PII properties in log messages -
In Microsoft.IdentityModel logs, previously only system metadata (DateTime, class name, httpmethod etc.) was displayed in clear text. For all other log arguments, the type was being logged to prevent Personally Identifiable Information (PII) from being displayed when ShowPII flag is turned OFF. To improve troubleshooting experience non-PII properties - Issuer, Audience, Key location, Key Id (kid) and some SAML constants will now be displayed in clear text. See issue #​1903 for more details.

Prefix Wilson header message to the first log message -
To always log the Wilson header (Version, DateTime, PII ON/OFF message), EventLogLevel.LogAlways was mapped to LogLevel.Critical in Microsoft.IdentityModel.LoggingExtensions.IdentityLoggerAdapter class which caused confusion on why header was being displayed as a fatal log.
To address this, header is now prefixed to the first message logged by Wilson and separated with a newline. EventLogLevel.LogAlways has been remapped to LogLevel.Trace. See issue #​1907 for more details.

Bug Fixes:

Copy the IssuerSigningKeyResolverUsingConfiguration delegate in Clone() #​1909

6.21.0

Dependency Updates:

Updated Newtonsoft dependency to 13.0.2 #​1902

Bug Fixes:

Add M.IM.TestExtensions to strong name by pass. #​1897

Add early alerting for governance #​1896

Adjust log level #​1893

Fundamentals

Update newtonsoft per governance report #​1890

6.20.0

New Feature:

Microsoft.IdentityModel now provides a LoggerContext class to aid with debugging. See issue #​1876 for details.

Bug Fixes:

The cty claim is now optional. See issue #​1861 for details.

The signature of the token is no longer logged. See issue #​1880 for details.

ValidateHash method Alg is null when token is a JWE token. See issue #​1680 for details.

Fixed the issue the compaction actions are queued but potentially never got started. See issue #​1871 for details.

Enhancements

  • Introducing IdentityLoggerAdapter for Identity Libraries integrating (#​1862)

6.18.0

Enhancements

  • Added the ValidateTokenAsyc() and ReadToken() methods to all token handlers (#​1810).

6.15.1

Enhancements

  • DisposableObjectPool disposes of objects on Free() when full (#​1802).

Bugs

  • TestTokenCreator modified to throw SecurityTokenInvalidSignatureException rather than ArgumentException(#​1798).
  • AadIssuerValidator fixed issue where AadIssuerValidatorConstants.Tid was used where AadIssuerValidatorConstants.TenantId should have been used (#​1801).

6.14.1

Bug Fixes:

The AadIssuerValidator in Microsoft.IdentityModel.Validators now uses the entire authority (instance + tenant ID), not just the authority host when validating the issuer. This was an issue which arose when using multiple authentication schemes. See issue #​1752 .

6.14.0

New Features

A new assembly, Microsoft.IdentityModel.Validators, is available! It provides an issuer validator for the Microsoft identity platform (AAD and AAD B2C), working for single and multi-tenant applications and v1 and v2 token types. See #​1736 and Microsoft.Identity.Web issue.

Bug Fixes

Fixes to determine when IsValid property has been checked. Includes a warning so developers ensure that token validation succeeded before reading the claims. See #​1718.

aka.ms link added for issuer validation failure. See issue #​1732.

Fix broken rfc link. See issue #​1728.

Add const for the OIDC scope "phone". See #​1720.

Use https for hyperlinks in XLM. See #​1719.

6.13.1

Updating comments to help improve correct usage
#​1705

SignedHttpRequests
New exceptions and delegate for validation.
#​1704

Base64UrlEncoder performance improvements
#​1698

Improve comments to clarify API usage and avoid unintentional validation weakening
#​1687

Modify how internal caching runs tasks
Change to starting the event queue task via the Task.Run() method so it is on the default task scheduler and will not interfere with caller's task scheduler as some custom task schedulers might be single threaded and execution can be blocked. The second change is replacing the BlockingCollection with ConcurrentQueue to prevent resource leaks
#​1696

Adding the BaseConfigurationManager and BaseConfiguration
This simplifies access to first class properties such as RefreshInterval etc.
Some of the properties in TokenValidationParameter were left as internal as they are required for a future feature that requires additional work.
#​1695

NOTE: Version 6.13.0 should NOT be used. In version 6.13.0, users were experiencing an issue where they could not use a ConfigurationManager where T is a custom class. This has been addressed in 6.13.1.

Stop the event queue task when event queue is empty (#​1685)
