## Generating self-signed certs
```sh
# Write defaults and update.
# NOTE: this doesn't need to be run if regenerating old certificates and
# shouldn't as it overrides non-default values.
cfssl print-defaults csr > ca-csr.json
cfssl print-defaults csr > ca-bad-csr.json
cfssl print-defaults config > ca-config.json

# Generate CA certificates and keys.
#
# 1. Generates ca.csr, ca.pem, and ca-key.pem.
# 2. Generates ca-bad.csr, ca-bad.pem, and ca-bad-key.pem.
cfssl gencert -loglevel=5 -config ca-config.json -initca ca-csr.json | cfssljson -bare ca -
cfssl gencert -loglevel=5 -config ca-config.json -initca ca-bad-csr.json | cfssljson -bare ca-bad -

# Generate certificates and keys.
#
# 1. Generates nomad-foo.csr, nomad-foo.pem, and nomad-foo-key.pem.
# 1. Generates nomad-bad.csr, nomad-bad.pem, and nomad-bad-key.pem.
cfssl gencert -loglevel=5 -ca ca.pem -ca-key ca-key.pem -config ca-config.json nomad-foo-csr.json | cfssljson -bare nomad-foo
cfssl gencert -loglevel=5 -ca ca-bad.pem -ca-key ca-bad-key.pem -config ca-config.json nomad-bad-csr.json | cfssljson -bare nomad-bad
