I am trying to run: ipsec pki --self --in iOScaKey.pem --dn "C=CH, O=ELC, CN=strongSwan CA" --ca --outform pem > iOScaCert.pem and get: /usr/lib64/ipsec/pki: unrecognized option '--outform' Is this because we are running 4.5.x of strongSwan? If so, how can we produce a pem with ipsec pki tool in 4.5?
