A common problem that I see with questions is that they ask something like "Is (x) secure", which to me is an unanswerable question, the same way as asking "is the city north", it has no meaning in an absolute sense and requires context
In order for a question to make sense the asker needs to provide some details on what they're looking to secure and from whom they are looking to secure it. So instead of asking:
"is this algorithm secure?"
it would be something like:
"I'm writing an application which will store data on disk for an e-commerce website which processes financial transactions. I want to encrypt my data to protect it in the event that my server is compromised, would this algorithm help me achieve that goal"
In terms of a FAQ entry, something like:
Asking questions about whether something is "secure" or not is unlikely to get a satisfactory answer as, without additional details about the system or process you are trying to secure and information about who you are trying to secure it from it is not generally possible to provide an answer which is likely to be accurate. Please ensure that this information is included, otherwise your question may end up being closed.
