# The purpose of the next two tests is to test the client's behaviour when receiving a server
# certificate with an unsupported elliptic curve. This should usually not happen because
# the client informs the server about the supported curves - it does, though, in the
# corner case of a static ECDH suite, because the server doesn't check the curve on that
# occasion (to be fixed). If that bug's fixed, the test needs to be altered to use a
# different means to have the server ignoring the client's supported curve list.
