Replumbing: add a configuration module for providers
This configuration module supports a configuration structure pretty
much like the engine configuration module, i.e. something like this:
openssl_conf = openssl_init
[openssl_init]
providers = provider_section
[provider_section]
# Configure the provider named "foo"
foo = foo_section
# Configure the provider named "bar"
bar = bar_section
[foo_section]
# Override name given in the provider section
identity = myfoo
# The exact path of the module. This is platform specific
module_path = /opt/openssl/modules/foo.so
# Whether it should be automatically activated. Value is unimportant
activate = whatever
# Anything else goes as well, and becomes parameters that the
# provider can get
what = 1
# sub-sections will be followed as well
ever = ever_section
[ever_section]
cookie = monster
All the configurations in a provider section and its sub-sections
become parameters for the provider to get, i.e. the "foo" provider
will be able to get values for the following keys (with associated
values shown):
