#REGTEST_TYPE=devel

|
|
# This reg-tests checks that the DH-related mechanisms works properly.
|
|
# When no DH is specified, either directly in the server's PEM or through a
|
|
# ssl-dh-param-file global option, and no tune.ssl.default-dh-param is defined,
|
|
# DHE ciphers are disabled.
|
|
# If a default-dh-param is defined, we will use DH parameters of the same size
|
|
# as the server's RSA or DSA key, or default-dh-param if it is smaller.
|
|
# This test has three distinct HAProxy instances, one with no DH-related option
|
|
# used, one with the tune.ssl.default-dh-param global parameter set, and one
|
|
# with an ssl-dh-param-file global option.
|
|
# We use "openssl s_client" calls in order to check the size of the "Server
|
|
# Temp Key" (which will be the same as the DH parameters in case a DHE cipher
|
|
# is used).
|
|
#
|
|
# The main goal of this test was to check that the newly added OpenSSLv3
|
|
# specific DH code worked as before, since it needed to be created in order to
|
|
# stop using deprecated APIs.
