WebMar 26, 2024 · There are three lengths of AES encryption keys. Each key length has a different number of possible key combinations: 128-bit key length: 3.4 x 1038 192-bit key length: 6.2 x 1057 256-bit key length: 1.1 x 1077 While the key length of this encryption method varies, its block size – 128-bits (or 16 bytes) – remains the same. WebAES should always take in and return 128 bit block sizes. On a different point, it sounds like you are using ECB mode and should consider changing to use a stronger block cipher mode, like CBC.
