step-cli lets you build, operate, and automate Public Key Infrastructure (PKI)
systems and workflows. It's a swiss army knife for authenticated encryption
(X.509, TLS), single sign-on (OAuth OIDC, SAML), multi-factor authentication
(OATH OTP, FIDO U2F), encryption mechanisms (JSON Web Encryption, NaCl),
and verifiable claims (JWT, SAML assertions).
