Every now and then we will have new users and all welcome to ask questions ( and also provide answers - this is another subject).
Most of the time we see that the questions are weak
- No background is given; CTF, homework, the source.
- Only links provided to read, no page and paragraph or the better the quotation form the source are provided.
- Too many questions ( a record was 28 question mark that I've seen)
- The aim is missing,
- and, so on..
So the question is How to write a good question on Cryptography.SE
