alt Hacker NewsI'm not sure there's a realistic alternative. If you need to generate a key then it has to happen somehow on unsupported platforms. You can check Enabled() if you need to know and intend to do something different but I assume most of the time you run the same function either way you'd just prefer to opt into secret mode if it's available.
This is not what secret.Enabled() means. But it probably illustrates that the function needs to be renamed already. Here's what the doc comment says:
In other words, it is just a way of checking that you are indeed running inside the context of some secret.Do call; it doesn't guarantee that secret.Do is actually offering the protection you may desire.
