# acme.Registration

The acme.Registration resource can be used to create and manage accounts on an ACME server. Once registered, the same private key that has been used for registration can be used to request authorizations for certificates.

This resource is named acme.Registration for historical reasons - in the ACME v1 spec, a registration referred to the account entity. This resource name is stable and there are no plans to change it.

Keep in mind that when using this resource along with acme.Certificate within the same configuration, a change in the provider-level serverUrl (example: from the Let’s Encrypt staging to production environment) within the same Terraform state will result in a resource failure, as Terraform will attempt to look for the account in the wrong CA. Consider different workspaces per environment, and/or using multiple provider instances.

Example

Basic Example

The following is the most basic example. In this case, the account private key is managed for you.

import * as pulumi from "@pulumi/pulumi";
import * as acme from "@pulumiverse/acme";

const reg = new acme.Registration("reg", {});

import pulumi
import pulumiverse_acme as acme

reg = acme.Registration("reg")

package main

import (
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
	"github.com/pulumiverse/pulumi-acme/sdk/go/acme"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := acme.NewRegistration(ctx, "reg", nil)
		if err != nil {
			return err
		}
		return nil
	})
}

using System.Collections.Generic;
using System.Linq;
using Pulumi;
using Acme = Pulumiverse.Acme;

return await Deployment.RunAsync(() => 
{
    var reg = new Acme.Registration("reg");

});

package generated_program;

        var reg = new Registration("reg");

    }
}

Using a Pre-Existing Private Key

The following creates an account off of a private key generated with the tlsPrivateKey resource.

import * as pulumi from "@pulumi/pulumi";
import * as acme from "@pulumiverse/acme";
import * as tls from "@pulumi/tls";

const privateKey = new tls.index.PrivateKey("private_key", {algorithm: "RSA"});
const reg = new acme.Registration("reg", {accountKeyPem: privateKey.privateKeyPem});

import pulumi
import pulumi_tls as tls
import pulumiverse_acme as acme

private_key = tls.index.PrivateKey("private_key", algorithm=RSA)
reg = acme.Registration("reg", account_key_pem=private_key["privateKeyPem"])

package main

import (
	"github.com/pulumi/pulumi-tls/sdk/go/tls"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
	"github.com/pulumiverse/pulumi-acme/sdk/go/acme"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		privateKey, err := tls.NewPrivateKey(ctx, "private_key", &tls.PrivateKeyArgs{
			Algorithm: "RSA",
		})
		if err != nil {
			return err
		}
		_, err = acme.NewRegistration(ctx, "reg", &acme.RegistrationArgs{
			AccountKeyPem: privateKey.PrivateKeyPem,
		})
		if err != nil {
			return err
		}
		return nil
	})
}

using System.Collections.Generic;
using System.Linq;
using Pulumi;
using Acme = Pulumiverse.Acme;
using Tls = Pulumi.Tls;

return await Deployment.RunAsync(() => 
{
    var privateKey = new Tls.Index.PrivateKey("private_key", new()
    {
        Algorithm = "RSA",
    });

    var reg = new Acme.Registration("reg", new()
    {
        AccountKeyPem = privateKey.PrivateKeyPem,
    });

});

Argument Reference

NOTE: All arguments in acme.Registration force a new resource if changed.

The resource takes the following arguments:

accountKeyPem (Optional) - The private key used to identify the account. If not provided, the key will be generated according to the accountKeyAlgorithm, accountKeyEcdsaCurve, and accountKeyRsaBits settings.
accountKeyAlgorithm (Optional) - The algorithm to use for the private key when generating from scratch. Supported settings: RSA and EDCSA. Default settings: ECDSA.
accountKeyEcdsaCurve (Optional) - ECDSA curve to use for ECDSA key types. Supported settings: P256 and P384. Default: P384.
accountKeyRsaBits (Optional) - The key length to use for RSA key types. Supported settings: 2048, 3072, and 4096. Default: 4096.
emailAddress (Optional) - The contact email address for the account.

Note that Let’s Encrypt no longer sends expiry emails, and only uses this field for possible email list onboarding (see https://letsencrypt.org/2025/06/26/expiration-notification-service-has-ended). As such, it is not recommended to set this field when using Let’s Encrypt. Other CAs may or may not require this field - consult the documentation of the CA you are using in this case.

externalAccountBinding (Optional) - An external account binding for the registration, usually used to link the registration with an account in a commercial CA. Sub-options are:
- keyId (Required): The key ID for the external account binding.
- hmacBase64 (Required): The base64-encoded message authentication code for the external account binding.

Attribute Reference

The following attributes are exported:

id: The original full URL of the account.
accountKeyPem: The private key used to identify the account (will be generated if not provided).
registrationUrl: The current full URL of the account.

id and registrationUrl will usually be the same and will usually only diverge when migrating protocols, ie: ACME v1 to v2.
