A community-maintained archive of CTF (capture the flag) write-ups and challenge source files, organized by year from 2013 to 2017. It centralizes solutions that would otherwise be scattered across personal blogs and often lost.

Use cases

• find write-ups for a past CTF competition
• learn how to solve capture the flag challenges
• study security challenges as a beginner
• recover original challenge files for a CTF
• contribute my own CTF solution write-up

When to choose

• you need solutions or challenge files from CTFs held in 2013-2017
• you want complete, community-reviewed explanations suitable for newcomers
• you want a permanent archive that won't disappear like personal blogs

When to avoid

• you need write-ups for CTFs after 2017, as this archive is no longer updated
• you want an interactive CTF practice platform rather than written solutions
• you need a tool or library rather than a reference collection
