Abblix JWT

Abblix.JWT provides complete JWT signing, encryption, validation, and management built entirely on .NET cryptographic primitives and System.Text.Json.Nodes. It implements RFC 7515 (JWS), RFC 7516 (JWE), and RFC 7518 (JWA) with a JWT-optimized architecture that eliminates the Microsoft.IdentityModel.Tokens dependency.

What's New in Version 2.2

  • Custom JWT Implementation: Complete signing/encryption infrastructure using System.Text.Json.Nodes and .NET crypto primitives (RSA, ECDsa, AES) directly — no Microsoft.IdentityModel.Tokens dependency
  • Enhanced JWE Algorithms: RSA-OAEP-256 (SHA-256), AES-GCM key wrapping (A128GCMKW/A192GCMKW/A256GCMKW), and direct key agreement (dir) per RFC 7518
  • Operation Capability Validation: JsonWebKey classes now validate key operations (sign, verify, encrypt, decrypt) before use
  • Interoperability Verified: Bidirectional tests with Microsoft.IdentityModel.Tokens confirm full compatibility across unsigned JWTs, all signing algorithms, and JWE encryption combinations

Key Features

  • Signing Algorithms: RSA (RS256/RS384/RS512, PS256/PS384/PS512), ECDSA (ES256/ES384/ES512), HMAC (HS256/HS384/HS512)
  • Encryption Algorithms: RSA-OAEP, RSA-OAEP-256, AES-GCM key wrapping (A128GCMKW/A192GCMKW/A256GCMKW), direct key agreement (dir)
  • Content Encryption: A128CBC-HS256, A192CBC-HS384, A256CBC-HS512, A128GCM, A192GCM, A256GCM
  • Native JSON Types: JsonObject-based programming model handles numbers, arrays, and nested objects without string conversions
  • Exception-Free Validation: Try pattern throughout the validation pipeline for better performance
  • JWK Management: Full JSON Web Key lifecycle with operation capability checks
