I visit the encryption tag on SO and use the Unanswered tab to pick Questions to answer. In RSA-Algorithm Invalid Keys I do not know how to proceed.
Should I make a Community Wiki Answer from the Comment by CodesInChaos like it is stated in How to avoid unanswered questions with answers in comments? SO told me I cannot upvote the answer I just posted (I deleted it already) so it would further stay in Unanswered : (
Reading Enable automatic deletion of old, unanswered zero-score questions after a year? I have another option: If I downvote the question it would get deleted by the community user. As the question shows some work and provides a programming related answer I am not sure this is justified.
If my evaluation of the question / answer is not correct and this question is either clearly worthless or valuable please say so; But I would still like to know how to remove questions from "Unanswered" that are valuable and abandoned at the same time.
