Hi Vitaly, Stefan,

If this is an issue, perhaps call the equivalent of optarg_password()
to store the environment variable in secure heap memory.

Something like:
	imaevm_params.keypass =
optarg_password(getenv("EVMCTL_KEY_PASSWORD"));

optarg_password() would then become a wrapper around the new function.

thanks,

Mimi
