WebAug 18, 2024 · AES requires blocks of 16 bytes in length. If the last block of plaintext is less than 16 bytes, bytes are appended to make the length of this block 16 bytes, where the value of the appended bytes is the number of bytes appended (e.g. if 5 bytes are appended, the value of these bytes is 0x05).
