   // provider. Legacy is typically not enabled by default (but can be via
   // openssl.cnf) so it is loaded here. Explicitly loading a provider will
   // disable the automatic loading of the "default" one. The default might
   // not have already been loaded, or standard algorithms might be available
   // via another configured provider, such as FIPS. So an attempt is made to
   // fetch a common default algorithm, possibly automaticlly loading the
   // default provider. Afterwards the legacy provider is loaded.
