An access to +# the service is protected by client's certificate verification +# mechanism. Before using this configuration a server administrator +# must generate server certificate and private key as well as +# the certificate authority (CA). The clients' certificates must +# be signed by the CA. +# +# Note that the steps provided below to generate and setup certificates +# are provided as an example for testing purposes only. Always +# consider best known security measures to protect your production +# environment. +# +# The server certificate and key can be generated as follows: +# +# openssl genrsa -des3 -out kea-proxy.key 4096 +# openssl req -new -x509 -days 365 -key kea-proxy.key -out kea-proxy.crt +# +# The CA certificate and key can be generated as follows: +# +# openssl genrsa -des3 -out ca.key 4096 +# openssl req -new -x509 -days 365 -key ca.key -out ca.crt +# +# +# The client certificate needs to be generated and signed: +# +# openssl genrsa -des3 -out kea-client.key 4096 +# openssl req -new -key kea-client.key -out kea-client.csr +# openssl x509 -req -days 365 -in kea-client.csr -CA ca.crt \ +# -CAkey ca.key -set_serial 10 -out kea-client.crt +# +# Note that the 'common name' value used when generating the client +# and the server certificates must differ from the value used +# for the CA certificate. +# +# The client certificate must be deployed on the client system. +# In order to test the proxy configuration with 'curl' run +# command similar to the following: +# +# curl -k --key kea-client.key --cert kea-client.crt -X POST \ +# -H Content-Type:application/json -d '{ "command": "list-commands" }' \ +# https://kea.example.org/kea +# +# On some curl running on macOS the crypto library requires a PKCS#12 +# bundle with the private key and the certificate as the cert argument. +# The PKCS#12 file can be generated by: +# +# openssl pkcs12 -export -in kea-client.crt -inkey kea-client.key \ +# -out kea-client.p12 +# +# If the password is kea, curl command becomes: +# +# curl -k --cert kea-client.p12:kea -X POST \ +# -H Content-Type:application/json -d '{ "command": "list-commands" }' \ +# https://kea.example.org/kea +# +# +# In order to use this configuration within your Apache2 configuration +# put the following line in the main Apache 2 configuration file: +# +# Include /path/to/kea-httpd2.conf +# +# and specify a path appropriate for your system. +# +# +# Apache2 server configuration starts here. +# +# Address and port that the server should bind to. +# Usually an explicit address is specified to avoid binding to +# many addresses.
