CryptoHack – Symmetric Ciphers challenges

WebJan 5, 2024 · After a high-level overview of AES, and a section on what is wrong with ECB and CBC block cipher modes, the chapter introduces the concept of authenticated encryption with associated data (AEAD) and dedicates the most space to describing AES-GCM and ChaCha20-Poly1305. 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. WebMay 20, 2024 · Somebody estimated that if you turned the power of the entire Bitcoin mining network against an AES-128 key, it would take over a hundred times the age of the universe to crack the key. It turns out that there is an attack on AES that’s better than bruteforce, but only slightly – it lowers the security level of AES-128 down to 126.1 bits ... dwayne electrician

WebMay 20, 2024 · AES, like all good block ciphers, performs a “keyed permutation”. This means that it maps every possible input block to a unique output block, with a key determining which permutation to perform. A “block” just refers to a fixed number of bits or bytes, which may represent any kind of data. AES processes a block and outputs another ...
