JPKI.Net

Jpki.Security.Cryptography

This library contains extension methods that "backport" PKI-related methods introduced in .NET 5, 6, or 7 to older runtime versions, including:

• ECDsa.SignData overloads that accept a DSASignatureFormat parameter.
• ECDsa.VerifyData overloads that accept a DSASignatureFormat parameter.
• {ECDSA, RSA}.ExportSubjectPublicKeyInfo
• {ECDSA, RSA}.ExportSubjectPublicKeyInfoPem
• {ECDSA, RSA}.ImportSubjectPublicKeyInfo
• {ECDSA, RSA}.ImportFromPem
• RSA.ExportRSAPublicKey
• RSA.ExportRSAPublicKeyPem
• RSA.ImportRSAPublicKey
• X509Certificate2.ExportCertificatePem

The library uses the Windows CryptoAPI and CNG native APIs to implement these "missing" methods.

Jpki.Security.Cryptography has no runtime dependencies and supports the following runtimes:

• .NET Framework 4.7+
• .NET 6.0+ (Windows)

Jpki.Security.WebAuthn

This library is a managed wrapper for the (semi-documented) Windows Hello WebAuthn API to create WebAuthn assertions and credentials in .NET.

Jpki.Security.WebAuthn depends on Jpki.Security.Cryptography but has no further runtime dependencies. It supports the following runtimes:

• .NET Framework 4.7+
• .NET 6.0+ (Windows)
