📖 FluentCertificates Overview

⚠️ Note: while version numbers are v0.x.y, this software is under initial development and there'll be breaking-changes in its API from version to version.

NuGet Build & Publish GitHub license

FluentCertificates is a library using the Immutable Fluent Builder pattern for easily creating, finding and exporting certificates. Makes it simple to generate your own certificate chains, or just stand-alone self-signed certificates.

This project is published in several NuGet packages:

Unfortunately documentation is incomplete. You may find more examples within the project's unit tests.

CertificateBuilder examples

CertificateBuilder requires the FluentCertificates.Builder package and is found under the FluentCertificates namespace.

The absolute minimum needed to create a certificate (although it may not be a very useful one):

using var cert = new CertificateBuilder().Create();

Create a CertificateSigningRequest for signing, exporting and passing to a 3rd party CA:

//A public & private keypair must be created first, outside of the CertificateBuilder, otherwise you'd have no way to retrieve the private-key used for the new CertificateSigningRequest object
using var keys = RSA.Create();

//Creating a CertificateSigningRequest
var csr = new CertificateBuilder()
    .SetUsage(CertificateUsage.Server)
    .SetSubject(b => b.SetCommonName("*.fake.domain"))
    .SetDnsNames("*.fake.domain", "fake.domain")
    .SetKeyPair(keys)
    .CreateCertificateSigningRequest();

//The CertificateRequest object is accessible here:
var certRequest = csr.CertificateRequest;

//CSR can be exported to a string
Console.WriteLine(csr.ToPemString());

//Or to a file or StringWriter instance
csr.ExportAsPem("csr.pem");

Build a self-signed web server certificate:

//Using a fluent style
using var cert = new CertificateBuilder()
    .SetUsage(CertificateUsage.Server)
    .SetFriendlyName("Example self-signed web-server certificate")
    .SetSubject(b => b.SetCommonName("*.fake.domain"))
    .SetDnsNames("*.fake.domain", "fake.domain")
    .SetNotAfter(DateTimeOffset.UtcNow.AddMonths(1))
    .Create();

//And just to demonstrate using object initializers (I'll use fluent style from now on though)
using var builder = new CertificateBuilder() {
    Usage = CertificateUsage.Server,
    FriendlyName = "Example self-signed web-server certificate",
    Subject = new X500NameBuilder().SetCommonName("*.fake.domain"),
    DnsNames = new[] { "*.fake.domain", "fake.domain" },
    NotAfter = DateTimeOffset.UtcNow.AddMonths(1)
};
var cert = builder.Create();

Build a CA (certificate authority):

//A CA's expiry date must be later than that of any certificates it will issue
using var issuer = new CertificateBuilder()
    .SetUsage(CertificateUsage.CA)
    .SetFriendlyName("Example root CA")
    .SetSubject(b => b.SetCommonName("Example root CA"))
    .SetNotAfter(DateTimeOffset.UtcNow.AddYears(100))
    .Create();

Build a client-auth certificate signed by a CA:

//Note: the 'issuer' certificate used must have a private-key attached in order to sign this new certificate
using var cert = new CertificateBuilder()
    .SetUsage(CertificateUsage.Client)
    .SetFriendlyName("Example client-auth certificate")
    .SetSubject(b => b.SetCommonName("User: Michael"))
    .SetNotAfter(DateTimeOffset.UtcNow.AddYears(1))
    .SetIssuer(issuer)
    .Create();

Advanced: Build a certificate with customized extensions:

using var cert = new CertificateBuilder()
    .SetFriendlyName("Example certificate with customized extensions")
    .SetSubject(b => b.SetCommonName("Example certificate with customized extensions"))
    .AddExtension(new X509BasicConstraintsExtension(false, false, 0, true))
    .AddExtension(new X509KeyUsageExtension(X509KeyUsageFlags.DigitalSignature | X509KeyUsageFlags.KeyEncipherment | X509KeyUsageFlags.DataEncipherment, true))
    .AddExtension(new X509EnhancedKeyUsageExtension(new OidCollection { new(KeyPurposeID.AnyExtendedKeyUsage.Id) }, false))
    .SetIssuer(issuer)
    .Create();
