Abblix.Jwt​

JsonWebKeyFactory Class​

A factory for creating JsonWebKey objects for various cryptographic key types. Supports RSA, Elliptic Curve, and symmetric (HMAC) keys for JWT operations.

public static class JsonWebKeyFactory

Inheritance System.Object → JsonWebKeyFactory

Methods​

JsonWebKeyFactory.CreateEllipticCurve(string, string) Method​

Creates an Elliptic Curve JsonWebKey with a specified curve.

public static Abblix.Jwt.EllipticCurveJsonWebKey CreateEllipticCurve(string curve, string algorithm);

Parameters​

curve System.String​

The elliptic curve to use. Common values: P-256, P-384, P-521.

algorithm System.String​

The signing algorithm. Common values: ES256, ES384, ES512.

Returns​

EllipticCurveJsonWebKey
A EllipticCurveJsonWebKey suitable for ECDSA signing operations.

JsonWebKeyFactory.CreateHmac(string, Nullable<int>) Method​

Creates a symmetric (Octet) JsonWebKey for HMAC signing.

public static Abblix.Jwt.OctetJsonWebKey CreateHmac(string algorithm, System.Nullable<int> keySize=null);

Parameters​

algorithm System.String​

The HMAC algorithm. Common values: HS256, HS384, HS512.

keySize System.Nullable<System.Int32>​

The key size in bytes. Defaults based on algorithm: HS256=32, HS384=48, HS512=64.

Returns​

OctetJsonWebKey
A OctetJsonWebKey suitable for HMAC signing operations.

JsonWebKeyFactory.CreateRsa(string, string, int) Method​

Creates an RSA JsonWebKey with a specified algorithm.

public static Abblix.Jwt.RsaJsonWebKey CreateRsa(string usage, string? algorithm=null, int keySize=2048);

Parameters​

usage System.String​

The intended usage of the key, typically 'sig' for signing or 'enc' for encryption.

algorithm System.String​

The signing or encryption algorithm. Key size is determined automatically based on the algorithm.

keySize System.Int32​

The size of the RSA key in bits. If null, determined by algorithm (defaults to 2048).

Returns​

RsaJsonWebKey
A RsaJsonWebKey configured for the specified algorithm.
