WebSep 20, 2024 · The Advanced Encryption Standard (AES) is the most famous and widespread block cipher. It operates on 128 bit blocks, using keys of 128/256/512 bits, … WebBean Counter. The flag was in an encrypted PNG file with AES-ECB, as StepUpCounter was initialized with step_up=False, IV wasn’t updated during encryption.Considering the plain text is a PNG file, the header is known, the key size is 16, so use the first 16 bytes of cipher text to xor the first 16 bytes of PNG header to leak the key.
