Same technique in picoCTF: It's Not My Fault 2, StegoRSA, AES-ABC
Web1

Same technique in picoCTF: Live Art, secure-email-service, No FA
Reverse engineering1
Work out what a compiled program does without its source, then work backwards from the check to the input that passes it.

Same technique in picoCTF: Checkpass, WinAntiDbg0x100, WinAntiDbg0x200
