Welcome to Sapphire CTF, by Luma Development

Sapphire CTF is a beginners-level CTF developed by a student, with categories such as Bash, Crypto, Trivia, and more.

The CTF was originally made by the Sapphire Development Group to create a challenge for Sapphire Hacking & Coding's community. Since the shutdown of Sapphire Development Group, the CTF has laid dormant on a hard drive. Now its back, powered by the CTFd platform. We challenge you to give it a go.
