# Assumptions: easyrsa3 available in current dir, and functional openssl.
# This basic example puts the "offline" and "sub" PKI dirs on the same system.
# A real-world setup would use different systems and transport the public components.

# Build root CA:
EASYRSA_PKI=offline ./easyrsa init-pki
EASYRSA_PKI=offline ./easyrsa build-ca nopass

# Build sub-CA request:
EASYRSA_PKI=sub ./easyrsa init-pki
