A new -groupname option has been added to keytool -genkeypair so that a user can specify a named group when generating a key pair. For example, keytool -genkeypair -keyalg EC -groupname secpr1 will generate an EC key pair by using the secpr1 curve.
Because there might be multiple curves with the same size, using the -groupname option is preferred over the -keysize option.
