Bleichenbacher Oracle Demo

A guided walkthrough of the 1998 PKCS#1 v1.5 padding oracle attack. Each step asks what the attacker does next. You drive a server that leaks one bit per query: was the padding valid?

Educational training material. This game demonstrates an attack technique inside a sandboxed quiz UI for security learning. Do not apply these techniques against systems you do not own or have explicit written permission to test.
