Ctf emoji-aes
WebPrinciple. The principle of byte inversion is very simple, we observe the decryption process can find the following characteristics: The nth ciphertext packet can affect the n + 1 plaintext packet. Assuming that the n n ciphertext is grouped as Cn C n, the decrypted n n plaintext is grouped as P n P n. Then P n+1 = Cn xor f (Cn+1) P n + 1 = C n ... WebAES-GCM is an AEAD encryption scheme, which means that unlike AES-CBC or AES-CTR it also generates a tag ( MAC ) to authenticate the message. To do that it uses some operations over GF (2^ {256} GF (2256 ), which are really cool (explained later). Looking at the source code of the server it’s easy to see that the nonce is reused.
