#   tests/tls/ca.{crt,key}          Self signed CA certificate.
#   tests/tls/keydb.{crt,key}       A certificate with no key usage/policy restrictions.
#   tests/tls/client.{crt,key}      A certificate restricted for SSL client usage.
#   tests/tls/server.{crt,key}      A certificate restricted fro SSL server usage.
#   tests/tls/keydb.dh              DH Params file.
