Webb9 feb. 2024 · The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphertext. Webb3 maj 2024 · 1. Simple answer is no. Even though the encryption algorithm is keep in secret, there are bunch of works (cryptanalysis) to break such a "black box" encryption algorithm. But when you design encryption algorithm (block cipher in this case), you have to evaluate your cihper against from known attack methods.
