The challenge is a hard-level CTF that tests your ability to exploit a Padding Oracle Attack . The goal is to decrypt ciphertext without knowing the encryption key by observing how the server responds to modified padding. Step-by-Step Walkthrough 1. Identify the Vulnerability
: To get all the flags, you often have to decrypt a token, modify it using bit-flipping, and then re-encrypt it to perform a SQL injection. Are you stuck on a specific flag or just starting out with the Padding Oracle CTF — Hacker101 — Encrypted Pastebin | by Ravid Mazon hacker101 encrypted pastebin
Use modern modes like AES-GCM or ChaCha20-Poly1305 , which handle both encryption and integrity naturally. Conclusion Hacker101 "Encrypted Pastebin" The challenge is a hard-level
