JsonWebKeyExtensions Class​

Provides extensions for asynchronous operations on a sequence of JsonWebKey objects.

public static class JsonWebKeyExtensions

Inheritance System.Object → JsonWebKeyExtensions

Methods​

JsonWebKeyExtensions.FirstByAlgorithmAsync(this IAsyncEnumerable<JsonWebKey>, string) Method​

Asynchronously retrieves the first JsonWebKey with the specified algorithm from the sequence. Prioritizes keys with exact algorithm match, then falls back to algorithm-agnostic keys (Algorithm == null) per RFC 7517, which allows keys without 'alg' parameter to be used with any compatible algorithm.

public static System.Threading.Tasks.Task<Abblix.Jwt.JsonWebKey?> FirstByAlgorithmAsync(this System.Collections.Generic.IAsyncEnumerable<Abblix.Jwt.JsonWebKey> credentials, string? algorithm);

Parameters​

credentials System.Collections.Generic.IAsyncEnumerable<JsonWebKey>​

The asynchronous sequence of JsonWebKey objects.

algorithm System.String​

The algorithm to match. Returns null if None is provided.

Returns​

System.Threading.Tasks.Task<JsonWebKey>
The first JsonWebKey with the specified algorithm or null if not found.
