#REGTEST_TYPE=devel

# This reg-test checks that the 'generate-certificates' SSL option works
# properly. This option allows to generate server-side certificates on the fly
# for clients that use an SNI for which no certificate was specified in the
# configuration file.
# This test also aims at checking that the 'generate-certificates' and the
# 'ecdhe' bind options work correctly together.
# Any bind line having a 'generate-certificates' needs to have a ca-sign-file
# option as well that specifies the path to a CA pem file (containing a
# certificate as well as its private key). For this reason, a new
# ssl_gen_ca.pem CA certificate was created, along with the ssl_gen_server.pem
# server certificate signed by the CA. This server certificate will be used as
# a default certificate and will serve as a base for any newly created
# certificate.
