step-ca is an online Certificate Authority (CA) for secure, automated X.509 and SSH certificate management. It's the server counterpart to step CLI. It is secured with TLS, and it offers several configurable certificate provisioners, flexible certificate templating, and pluggable database backends to suit a wide variety of contexts and workflows. It employs sane default algorithms and attributes, so you don't have to be a security engineer to use it securely.
