step-ca
step-ca
is an online certificate authority for secure, automated certificate management for DevOps.
It's the server counterpart to the step
CLI tool for working with certificates and keys.
Both projects are maintained by Smallstep Labs.
You can use step-ca
to:
- Issue HTTPS server and client certificates that work in browsers (RFC5280 and CA/Browser Forum compliance)
- Issue TLS certificates for DevOps: VMs, containers, APIs, database connections, Kubernetes pods...
- Issue SSH certificates:
- For people, in exchange for single sign-on identity tokens
- For hosts, in exchange for cloud instance identity documents
- Easily automate certificate management:
- It's an ACME server that supports all popular ACME challenge types
- It comes with a Go wrapper
- ... and there's a command-line client you can use in scripts!
Comparison with Smallstep's commercial product
step-ca
is optimized for a two-tier PKI serving common DevOps use cases.
As you design your PKI, if you need any of the following, consider our commerical CA:
- Multiple certificate authorities
- Active revocation (CRL, OSCP)
- Turnkey high-volume, high availability CA
- An API for seamless IaC management of your PKI
- Integrated support for SCEP & NDES, for migrating from legacy Active Directory Certificate Services deployments
- Device identity — cross-platform device inventory and attestation using Secure Enclave & TPM 2.0
- Highly automated PKI — managed certificate renewal, monitoring, TPM-based attested enrollment
- Seamless client deployments of EAP-TLS Wi-Fi, VPN, SSH, and browser certificates
- Jamf, Intune, or other MDM for root distribution and client enrollment
- Web Admin UI — history, issuance, and metrics
- ACME External Account Binding (EAB)
- Deep integration with an identity provider
- Fine-grained, role-based access control
- FIPS-compliant software
- HSM-bound private keys

Features
🦾 A fast, stable, flexible private CA
Setting up a public key infrastructure (PKI) is out of reach for many small teams. step-ca
makes it easier.
- Choose key types (RSA, ECDSA, EdDSA) and lifetimes to suit your needs
- Short-lived certificates with automated enrollment, renewal, and passive revocation
- Can operate as an online intermediate CA for an existing root CA
- Badger, BoltDB, Postgres, and MySQL database backends
⚙️ Many ways to automate
There are several ways to authorize a request with the CA and establish a chain of trust that suits your flow.
You can issue certificates in exchange for:
- ACME challenge responses from any ACMEv2 client
- OAuth OIDC single sign-on tokens, eg:
- Cloud instance identity documents, for VMs on AWS, GCP, and Azure
- Single-use, short-lived JWK tokens issued by your CD tool — Puppet, Chef, Ansible, Terraform, etc.
- A trusted X.509 certificate (X5C provisioner)
- A host certificate from your Nebula network
- A SCEP challenge (SCEP provisioner)
- An SSH host certificates needing renewal (the SSHPOP provisioner)
- Learn more in our provisioner documentation
🏔 Your own private ACME server
ACME is the protocol used by Let's Encrypt to automate the issuance of HTTPS certificates. It's super easy to issue certificates to any ACMEv2 (RFC8555) client.
-
Supports the most popular ACME challenge types:
- For
http-01
, place a token at a well-known URL to prove that you control the web server - For
dns-01
, add aTXT
record to prove that you control the DNS record set - For
tls-alpn-01
, respond to the challenge at the TLS layer (as Caddy does) to prove that you control the web server
- For
-
Works with any ACME client. We've written examples for:
-
Get certificates programmatically using ACME, using these libraries:
lego
for Golang (example usage)- certbot's
acme
module for Python (example usage) acme-client
for Node.js (example usage)
-
Our own
step
CLI tool is also an ACME client! -
See our ACME tutorial for more
👩🏽💻 An online SSH Certificate Authority
- Delegate SSH authentication to
step-ca
by using SSH certificates instead of public keys andauthorized_keys
files - For user certificates, connect SSH to your single sign-on provider, to improve security with short-lived certificates and MFA (or other security policies) via any OAuth OIDC provider.
- For host certificates, improve security, eliminate TOFU warnings, and set up automated host certificate renewal.
🤓 A general purpose PKI tool, via step
CLI integration
- Generate key pairs where they're needed so private keys are never transmitted across the network
- Authenticate and obtain a certificate using any provisioner supported by
step-ca
- Securely distribute root certificates and bootstrap PKI relying parties
- Renew and revoke certificates issued by
step-ca
- Install root certificates on your machine and browsers, so your CA is trusted
- Inspect and lint certificates
