Creating a test CA using the Smallstep CLI

posted 2021-11-19

The step command-line tool has lots of guardrails to prevent you from creating a certificate authority in an insecure manner; these are very inconvenient when you just want a few certificates to play around with. Here is my usual test script which bypasses all of this:

step certificate create ca ca.crt ca.key --profile root-ca --no-password --insecure
step certificate create one one.csr one.key --csr --profile leaf --no-password --insecure
step certificate create two two.csr two.key --csr --profile leaf --no-password --insecure
step certificate sign one.csr ca.crt ca.key > one.crt
