Certificates

Last updated Apr 23, 2026 Use these commands to manage certificates for mTLS connections.

The mtls-certificate commands manage client certificates for Worker subrequests. The cert commands manage both mTLS client certificates and Certificate Authority (CA) chain certificates, primarily for use with Hyperdrive configurations.

mtls-certificate

Manage client certificates used for mTLS connections in subrequests.

These certificates can be used in mtls_certificate bindings, which allow a Worker to present the certificate when establishing a connection with an origin that requires client authentication (mTLS).

mtls-certificate upload

Upload an mTLS certificate

npmyarnpnpm

npx wrangler mtls-certificate upload

yarn wrangler mtls-certificate upload

pnpm wrangler mtls-certificate upload
  • --cert string required

The path to a certificate file (.pem) containing a chain of certificates to upload - --key string required

The path to a file containing the private key for your leaf certificate - --name string The name for the certificate

  • <code>--v</code><code>boolean</code> alias: --version

The following is an example of using the upload command to upload an mTLS certificate.

npx wrangler mtls-certificate upload --cert cert.pem --key key.pem --name my-origin-cert

Uploading mTLS Certificate my-origin-cert...
Success! Uploaded mTLS Certificate my-origin-cert
ID: 99f5fef1-6cc1-46b8-bd79-44a0d5082b8d
Issuer: CN=my-secured-origin.com,OU=my-team,O=my-org,L=San Francisco,ST=California,C=US
Expires: 1/01/2025

You can then add this certificate as a binding in your Wrangler configuration file:

{
    "mtls_certificates": [
        {
            "binding": "MY_CERT",
            "certificate_id": "99f5fef1-6cc1-46b8-bd79-44a0d5082b8d",
        },
    ],
}

[[mtls_certificates]]
binding = "MY_CERT"
certificate_id = "99f5fef1-6cc1-46b8-bd79-44a0d5082b8d"

Note that the certificate and private keys must be in separate (typically .pem) files when uploading.

cert

Manage mTLS client certificates and Certificate Authority (CA) chain certificates used for secured connections.

These certificates can be used in Hyperdrive configurations, enabling them to present the certificate when connecting to an origin database that requires client authentication (mTLS) or a custom Certificate Authority (CA).
