| Package | Target Frameworks | Primary Purpose | Key Types | |---------|-------------------|----------------|-----------| | Psndlnet.Core | .NET Standard 2.1, .NET 6+ | Base abstractions (interfaces, models, exception hierarchy) | IPsnClient, PsnResponse<T> | | Psndlnet.Http | .NET Standard 2.1, .NET 6+ | HTTP wrapper built on HttpClient with forced TLS 1.2/1.3 | PsnHttpClient, PsnRequestOptions | | Psndlnet.Auth | .NET Standard 2.1, .NET 6+ | OAuth 2.0 token acquisition, refresh, revocation | PsnAuthenticator, OAuthToken | | Psndlnet.SecureStorage | .NET Standard 2.1, .NET 6+ | Secure persistance of tokens/keys (DPAPI, Keychain, Android Keystore) | ISecureTokenStore, FileSecureStore | | Psndlnet.Logging (optional) | .NET Standard 2.1, .NET 6+ | Structured logging of request/response metadata (never logs payloads) | PsnLogger, LogLevel |

Note: All packages are version‑matched; e.g., Psndlnet.Http v2.3.0 works only with Psndlnet.Core v2.3.0. Keep them synchronized. https psndlnet packages

        .ConfigurePrimaryHttpMessageHandler(() =>
var handler = new HttpClientHandler();
            handler.ServerCertificateCustomValidationCallback = (request, cert, chain, errors) =>
// Expected SHA‑256 fingerprint of api.playstation.com TLS cert
                const string ExpectedThumbprint = "A1B2C3D4E5F67890123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0";
// Compare thumbprint (case‑insensitive)
                var actual = cert.GetCertHashString(HashAlgorithmName.SHA256);
                return string.Equals(actual, ExpectedThumbprint, StringComparison.OrdinalIgnoreCase);
            ;
            return handler;
        );

Security tip: Keep the pinned thumbprint in a secure, version‑controlled location. Rotate it whenever Sony renews the certificate. using Microsoft
