Can AES work with Cyrillic letters? No, AES is a block cipher that can only operate on blocks of 16 bytes. AES may be securily used within a mode of operation to operate on plaintext of any bit/byte size. So you only have to encode your Cyrillic letters to any bit or byte encoding. Unicode - which designates code points to a huge range of characters - ...


Modern cryptographic algorithms are specified in terms of bytes or even bits, not characters. Whether the data you encrypt happens to represent latin or cyrillic letters or pictures or audio data or anything else does not matter at all to an encryption algorithm; all it ever sees is a bunch of bytes. What this means in practice is: You have to fix some ...


Modern cryptographic algorithms work on strings of bits, independently of how such strings are interpreted in any specific application.
