This release contains work from the following PRs and commits:
- Introduce ConfigurationValidationException(#2076)
- Disarm security artifacts(#2064)
- Throw SecurityTokenMalformedTokenException on malformed tokens(#2080)
- Add ClaimsMapping to JsonWebTokenHandler
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.
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

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 PR offers extensibility to re-add the claims mapping.
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.
