WebMar 17, 2024 · Some modes such as EAX and GCM provide authenticated encryption: a ciphertext will only be decrypted if it's genuine. Use one of these if possible. Note also that AES-128 is just as secure in practice as AES-256. If you aren't comfortable with what you're doing, try to use some high-level library rather than grappling with the crypto directly. WebMany block ciphers use XOR. Let's take AES: The Advanced Encryption Standard uses xor on single bytes (some other algorithms use blocks of 16 or 32 bits; there's no problem with sizes other than 8 bits). The round key will be XORed with the intermediate result and after that permuted and substituted. XOR also gets used in the key shedule. boty music
