-## ACME certificate issuance
-
-Starting with Vault 1.14, Vault supports the [ACME certificate lifecycle
-management protocol](https://datatracker.ietf.org/doc/html/rfc8555) for issuing
-and renewing leaf server certificates.
-
-In order to use ACME, a [cluster path](#set-cluster-configuration) must be
-set and ACME must be [enabled in its configuration](#set-acme-configuration)
-with the [required headers](#acme-required-headers) enabled on the mount
-tuning.
-
-Using ACME with a role requires `no_store=false` to be set on the role; this
-allows the certificate to be stored and later fetched through the ACME
-protocol.
-
-### ACME directories
-
-Vault PKI supports the following ACME directories, providing different
-restrictions around usage (defaults, a specific issuer and/or a specific
-role). To interact with these directories, specify the directory URL in
-an ACME client. For example, with the EFF's [CertBot](https://certbot.eff.org/):
-
-```
-$ certbot certonly --server https://localhost:8200/v1/pki/acme/directory ...
-```
-
-These endpoints are unauthenticated from a Vault authentication model, but
-internally authenticated via the ACME protocol.
-

-| `ACME` | `/pki/external-policy(/:policy)/acme/directory`                    | (any)                      | Specified by CIEPS    | CIEPS         |
-| `ACME` | `/pki/issuer/:issuer_ref/external-policy(/:policy)/acme/directory` | (any)                      | Specified by CIEPS    | CIEPS         |
-
-When a role is not explicitly specified, behavior is specified by the
-`default_directory_policy` in the [ACME configuration](#set-acme-configuration).
-These directories can also be forbidden by setting that policy as `forbid`.  If
-the policy is `sign-verbatim` then _any_ identifier for which the client can
-prove ownership of will be issued for.  This is similar to using the
-[Sign Verbatim](#sign-verbatim) endpoint, but with additional verification
-that the client has proven ownership (within the ACME protocol) of the
-requested certificate identifiers. When `external-policy` is specified as the
-default value, the Certificate Issuance External
-Policy Service (CIEPS)<EnterpriseAlert inline="true" /> is used for
-validating and templating the certificate instead of a role; ACME's challenge
-validation is still enforced. An optional policy name can be specified by using
-`external-policy:policy`. Roles are not used when CIEPS is used.
-
-#### ACME challenge types
-
-Vault supports the following ACME challenge types presently:
-
- - `http-01`, supporting both `dns` and `ip` identifiers.
- - `dns-01`, supporting `dns` identifiers including wildcards.
- - `tls-alpn-01`, supporting only non-wildcard `dns` identifiers.
-
-A custom DNS resolver used by the server for looking up DNS names for use
-with both mechanisms can be added via the [ACME configuration](#set-acme-configuration).
-
-#### ACME external account bindings
-
-ACME External Account Binding (EAB) Policy can enforce that clients need to
-have a valid external account binding to Vault. Before registering a new account,
-an authenticated Vault client will need to [fetch a new EAB
-token](#get-acme-eab-binding-token). This returns two values: a key identifier
-and an HMAC key used by the ACME client to authenticate with EAB. For example:
-
-```
-$ vault write -f /pki/acme/new-eab
-$ certbot certonly --server https://localhost:8200/v1/pki/acme/directory \
-                   --eab-kid <id> --eab-hmac-key <hmac-key>
-```
-
-With or without EAB, requests from the ACME client are not authenticated using
-traditional Vault authentication, but are instead authenticated through the
-ACME protocol. With EAB however, a Vault authenticated client will have to
-fetch an EAB token and pass it to the ACME client for use on the initial
-registration: this binds the ACME client's registration to an authenticated
-Vault endpoint, but not further to the client's entity or other information.
-
-~> Note: Enabling EAB is strongly recommended for public-facing Vault
-   deployments. Use of the `VAULT_DISABLE_PUBLIC_ACME` environment variable
-   can be used to enforce all ACME instances have EAB enabled.
-
-#### ACME accounts
-
-ACME Accounts are created specific to a particular directory and are not
-portable across Performance Secondary clusters.
-
-#### ACME required headers
-
-ACME requires the following response headers (`allowed_response_headers`)
-to be specified by [mount tuning](/vault/api-docs/system/mounts#tune-mount-configuration):
-
- - `Replay-Nonce`
- - `Link`
- - `Location`
-
-On an existing mount, these can be specified by running the following command:
-
-```
-$ vault secrets tune -allowed-response-headers=Location -allowed-response-headers=Replay-Nonce \
-                     -allowed-response-headers=Link \
-                     pki/
-```
-
-### Get ACME EAB binding token
-
-This endpoint returns a new ACME binding token. The `id` response field can
-be used as the key identifier and the `key` response field be used as the
-EAB HMAC key in the ACME Client.
-
-Each call to this endpoint will generate and return a new EAB binding token
-that is linked to the specific ACME directory it resides under. EAB tokens
-are not usable across different ACME directories.

-
-| Method | Path               |
-| :----- | :----------------- |
-| `POST` | `/pki/config/acme` |
-
-#### Parameters
-
- - `allowed_issuers` `(list: ["*"])` - Specifies a list issuers allowed to
-   issue certificates via explicit ACME paths. If an allowed role specifies
-   an issuer outside this list, it will be allowed. The default value `*`
-   allows every issuer within the mount.
-
-  - `allow_role_ext_key_usage` `(bool: false)` - whether the ExtKeyUsage field
-   from a role is used, defaults to false meaning that certificate will be
-   signed with ServerAuth.
-
- - `allowed_roles` `(list: ["*"])` - Specifies a list of roles allowed to
-   issue certificates via explicit ACME paths.  The default value `*` allows
-   every role within the mount to be used.  If the `default_directory_policy`
-   specifies a role, it must be allowed under this configuration.
-
- - `default_directory_policy` `(string: "sign-verbatim")` - Specifies the
-   behavior of the default ACME directory.  Can be `forbid`, `sign-verbatim`
-   or a role given by `role:<role_name>`.  If a role is used, it must be
-   present in `allowed_roles`.
-
- - `dns_resolver` `(string: "")` - An optional overriding DNS resolver to
-   use for challenge verification lookups. When not specified, the default
-   system resolver will be used. This allows domains on peered networks with
-   an accessible DNS resolver to be validated.
-
- - `eab_policy` `(string: "not-required")` - Specified policy to enforce
-   around [External Account Bindings (EABs)](#acme-external-account-bindings).
-   The allowed values are:
-
-     - `not-required`, where EABs are not enforced but are validated if
-        specified.
-
-     - `new-account-required`, where new accounts are required to have EAB
-       but existing accounts can still be used.
-
-     - `always-required`, where all accounts regardless of age are required
-       to have EABs set.
-
- - `enabled` `(bool: false)` - Whether ACME is enabled on this mount. When
-   ACME is disabled, all requests to ACME directory URLs will return 404.
-
- - `max_ttl` `(string: "")` - Specifies the maximum Time To Live provided as a
-   string duration with time suffix. Hour is the largest suffix. If not set,
-   defaults to the previous hard-coded behavior of 90 days (2160 hours).

+## ACME certificate issuance
+
+Starting with Vault 1.14, Vault supports the [ACME certificate lifecycle
+management protocol](https://datatracker.ietf.org/doc/html/rfc8555) for issuing
+and renewing leaf server certificates.
+
+In order to use ACME, a [cluster path](#set-cluster-configuration) must be
+set and ACME must be [enabled in its configuration](#set-acme-configuration)
+with the [required headers](#acme-required-headers) enabled on the mount
+tuning.
+
+Using ACME with a role requires `no_store=false` to be set on the role; this
+allows the certificate to be stored and later fetched through the ACME
+protocol.
+
+### ACME directories
+
+Vault PKI supports the following ACME directories, providing different
+restrictions around usage (defaults, a specific issuer and/or a specific
+role). To interact with these directories, specify the directory URL in
+an ACME client. For example, with the EFF's [CertBot](https://certbot.eff.org/):
+
+```
+$ certbot certonly --server https://localhost:8200/v1/pki/acme/directory ...
+```
+
+These endpoints are unauthenticated from a Vault authentication model, but
+internally authenticated via the ACME protocol.
+

+
+When a role is not explicitly specified, behavior is specified by the
+`default_directory_policy` in the [ACME configuration](#set-acme-configuration).
+These directories can also be forbidden by setting that policy as `forbid`.  If
+the policy is `sign-verbatim` then _any_ identifier for which the client can
+prove ownership of will be issued for.  This is similar to using the
+[Sign Verbatim](#sign-verbatim) endpoint, but with additional verification
+that the client has proven ownership (within the ACME protocol) of the
+requested certificate identifiers. When `external-policy` is specified as the
+default value, the Certificate Issuance External
+Policy Service (CIEPS)<EnterpriseAlert inline="true" /> is used for
+validating and templating the certificate instead of a role; ACME's challenge
+validation is still enforced. An optional policy name can be specified by using
+`external-policy:policy`. Roles are not used when CIEPS is used.
+
+#### ACME challenge types
+
+Vault supports the following ACME challenge types presently:
+
+ - `http-01`, supporting both `dns` and `ip` identifiers.
+ - `dns-01`, supporting `dns` identifiers including wildcards.
+ - `tls-alpn-01`, supporting only non-wildcard `dns` identifiers.
+
+A custom DNS resolver used by the server for looking up DNS names for use
+with both mechanisms can be added via the [ACME configuration](#set-acme-configuration).
+
+#### ACME external account bindings
+
+ACME External Account Binding (EAB) Policy can enforce that clients need to
+have a valid external account binding to Vault. Before registering a new account,
+an authenticated Vault client will need to [fetch a new EAB
+token](#get-acme-eab-binding-token). This returns two values: a key identifier
+and an HMAC key used by the ACME client to authenticate with EAB. For example:
+
+```
+$ vault write -f /pki/acme/new-eab
+$ certbot certonly --server https://localhost:8200/v1/pki/acme/directory \
+                   --eab-kid <id> --eab-hmac-key <hmac-key>
+```
+
+With or without EAB, requests from the ACME client are not authenticated using
+traditional Vault authentication, but are instead authenticated through the
+ACME protocol. With EAB however, a Vault authenticated client will have to
+fetch an EAB token and pass it to the ACME client for use on the initial
+registration: this binds the ACME client's registration to an authenticated
+Vault endpoint, but not further to the client's entity or other information.
+
+~> Note: Enabling EAB is strongly recommended for public-facing Vault
+   deployments. Use of the `VAULT_DISABLE_PUBLIC_ACME` environment variable
+   can be used to enforce all ACME instances have EAB enabled.
+
+#### ACME accounts
+
+ACME Accounts are created specific to a particular directory and are not
+portable across Performance Secondary clusters.
+
+#### ACME required headers
+
+ACME requires the following response headers (`allowed_response_headers`)
+to be specified by [mount tuning](/vault/api-docs/system/mounts#tune-mount-configuration):
+
+ - `Replay-Nonce`
+ - `Link`
+ - `Location`
+
+On an existing mount, these can be specified by running the following command:
+
+```
+$ vault secrets tune -allowed-response-headers=Location -allowed-response-headers=Replay-Nonce \
+                     -allowed-response-headers=Link \
+                     pki/
+```
+
+### Get ACME EAB binding token
+
+This endpoint returns a new ACME binding token. The `id` response field can
+be used as the key identifier and the `key` response field be used as the
+EAB HMAC key in the ACME Client.
+
+Each call to this endpoint will generate and return a new EAB binding token
+that is linked to the specific ACME directory it resides under. EAB tokens
+are not usable across different ACME directories.

+### Set ACME configuration
+
+This endpoint allows setting the ACME server configuration used by this
+mount.
+
+| Method | Path               |
+| :----- | :----------------- |
+| `POST` | `/pki/config/acme` |
+
+#### Parameters
+
+ - `allowed_issuers` `(list: ["*"])` - Specifies a list issuers allowed to
+   issue certificates via explicit ACME paths. If an allowed role specifies
+   an issuer outside this list, it will be allowed. The default value `*`
+   allows every issuer within the mount.
+
+  - `allow_role_ext_key_usage` `(bool: false)` - whether the ExtKeyUsage field
+   from a role is used, defaults to false meaning that certificate will be
+   signed with ServerAuth.
+
+ - `allowed_roles` `(list: ["*"])` - Specifies a list of roles allowed to
+   issue certificates via explicit ACME paths.  The default value `*` allows
+   every role within the mount to be used.  If the `default_directory_policy`
+   specifies a role, it must be allowed under this configuration.
+
+ - `default_directory_policy` `(string: "sign-verbatim")` - Specifies the
+   behavior of the default ACME directory.  Can be `forbid`, `sign-verbatim`
+   or a role given by `role:<role_name>`.  If a role is used, it must be
+   present in `allowed_roles`.
+
+ - `dns_resolver` `(string: "")` - An optional overriding DNS resolver to
+   use for challenge verification lookups. When not specified, the default
+   system resolver will be used. This allows domains on peered networks with
+   an accessible DNS resolver to be validated.
+
+ - `eab_policy` `(string: "not-required")` - Specified policy to enforce
+   around [External Account Bindings (EABs)](#acme-external-account-bindings).
+   The allowed values are:
+
+     - `not-required`, where EABs are not enforced but are validated if
+        specified.
+
+     - `new-account-required`, where new accounts are required to have EAB
+       but existing accounts can still be used.
+
+     - `always-required`, where all accounts regardless of age are required
+       to have EABs set.
+
+ - `enabled` `(bool: false)` - Whether ACME is enabled on this mount. When
+   ACME is disabled, all requests to ACME directory URLs will return 404.
+
+ - `max_ttl` `(string: "")` - Specifies the maximum Time To Live provided as a
+   string duration with time suffix. Hour is the largest suffix. If not set,
+   defaults to the previous hard-coded behavior of 90 days (2160 hours).

+page_title: Certificate Management Protocol v2 (CMPv2) within Vault | PKI - Secrets Engines
+description: An overview of the Certificate Management Protocol (v2) implementation within Vault.
+---
+
+# PKI secrets engine - Certificate Management Protocol v2 (CMPv2) <EnterpriseAlert inline="true" />
+
+This document summarizes Vault's PKI Secrets Engine
+implementation of the [CMPv2 protocol](https://datatracker.ietf.org/doc/html/rfc4210) <EnterpriseAlert inline="true" />,
+its configuration, and limitations.
+
+## What is Certificate Management Protocol v2 (CMPv2)?
+
+The CMP protocol is an IETF standardized protocol, [RFC 4210](https://datatracker.ietf.org/doc/html/rfc4210),
+that allows clients to acquire client certificates and their associated Certificate
+Authority (CA) certficates.
+
+## Enabling CMPv2 support on a Vault PKI mount
+
+To configure an existing mount to serve CMPv2 clients, the following steps are
+required, which are broken down into three main categories:
+
+ 1. [Configuring an Issuer](#configuring-an-issuer)
+ 1. [Authentication mechanisms](#configuring-cmpv2-authentication)
+ 1. [Updating PKI tunable parameters](#updating-the-pki-mount-tunable-parameters)
+ 1. [PKI CMPv2 configuration](#enabling-cmpv2)
+
+### Configuring an Issuer
+
+CMPv2 is a bit unique, in that it uses the Issuer CA certificate to sign the
+CMP messages.  This means your issuer must have the `DigitalSignature` key
+usage.
+Existing CA issuers likely do not have this, so you will need to generate a new 
+issuer (likely an intermediate) that has this property.  If you are configuring PKI 
+for the first time or creating a new issuer, ensure you set `key_usage` to,
+as an example, `CRL,CASign,DigitalSignature`.
+
+See [Generate intermediate CSR](/vault/api-docs/secret/pki#generate-intermediate-csr)
+
+### Configuring CMPv2 Authentication
+
+At this time, Vault's implementation of CMPv2 supports only 
+[Certificate TLS authentication](/vault/docs/auth/cert), where clients proof
+of posession of a TLS client certificate authenticates them to Vault.
+
+Authentication leverages a separate Vault authentication
+mount, within the same namespace, to validate the client provided credentials
+along with the client's ACL policy to enforce. 
+
+For proper accounting, a mount supporting CMPv2 authentication should be
+dedicated to this purpose, not shared with other workflows.  In other words,
+create a new certificate auth mount for CMPv2 even if you already have one 
+another in use for other purposes.
+
+When setting up the authentication mount for CMPv2 clients, the token type must
+be configured to return [batch tokens](/vault/docs/concepts/tokens#batch-tokens).
+Batch tokens are required to avoid an excessive amount of leases being generated
+and persisted as every CMPv2 incoming request needs to be authenticated.
+
+The path within an ACL policy must match the `cmp` path underneath the 
+PKI mount.  The path to use can be the default `cmp` path or a role based one.
+
+If using the `sign-verbatim` as a path policy, the following
+ACL policy will allow an authenticated client access the required PKI CMP path.
+```
+path “pki/cmp” {
+  capabilities=[“update”, “create”]
+}
+```
+
+For a role base path policy, this sample policy can be used
+```
+path “pki/roles/my-role-name/cmp” {
+  capabilities=[“update”, “create”]
+}
+```
+
+#### Updating the PKI mount tunable parameters
+
+Once the authentication mount has been created and configured, the authentication mount's accessor
+will need to be captured and added within the PKI mount's [delegated auth accessors](/vault/api-docs/system/mounts#delegated_auth_accessors).
+
+To get an authentication mount's accessor field, the following command can be used.
+
+```shell-session
+$ vault read -field=accessor sys/auth/auth/cert
+```
+
+For CMP to work within certain clients, a few response headers need to be explicitly allowed
+along with configuring the list of accessors the mount can delegate authentication towards.
+The following will grant the required response headers, you will need to replace the values for the `delegated-auth-accessors`
+to match your values.
+
+```shell-session
+$ vault secrets tune \
+  -allowed-response-headers="Content-Transfer-Encoding" \
+  -allowed-response-headers="Content-Length" \
+  -allowed-response-headers="WWW-Authenticate" \
+  -delegated-auth-accessors="auth_cert_4088ac2d" \
+  pki
+```
+
+#### Enabling CMPv2
+
+Enabling CMP is a matter of writing to the `config/cmp` endpoint, to set it
+enabled and configure default path policy and authentication.
+
+```shell-session
+vault write pki/config/cmp -<<EOC
+{
+  "enabled": true,
+  "default_path_policy": "role:example-role",
+  "authenticators": {
+    "cert": {
+      "accessor": "auth_cert_4088ac2d"
+    }
+  },
+  "audit_fields": ["common_name", "alt_names", "ip_sans", "uri_sans"]
+}
+EOC
+```
+
+Of course, substituting your own role and accessor values.  After this, the
+CMP endpoints will be able to handle client requests, authenticated with the 
+previously configured Cert Auth method.
+
+## Limitations
+
+The initial release of CMPv2 support is intentionally limited to a subset of the
+protocol, covering Initialization, Certification, and Key Update, over HTTP.
+In particular, the following are not yet supported:
+
+ * Basic authentication scheme using PasswordBasedMac
+ * Revocation
+ * CRL fetching via CMP itself.
+ * CA creation/update operations.
+
+Note that CMPv2 is not integrated with these existing Vault PKI features:
+ 
+ * Certificate Metadata - CMPv2 has no means of providing metadata.
+ * Certificate Issuance External Policy Service [(CIEPS)](/vault/docs/secrets/pki/cieps)
