WebDec 2, 2016 · One reason to not directly use bytes as key is that hardware devices (HSM's, smart cards) may not even expose the bytes to the software in the first place. In that case the error may be thrown in advance, depending on the implementation.

WebJun 16, 2024 · Sorted by: 1 Knowing some bytes of AES's uniform random key doesn't help you recover faster on brute force. Otherwise, we would hear that years ago. So you have 7 + 19 = 26 bytes for AES-256 which needs 32 bytes for the key. Therefore there are 6 bytes of the key is missing, equivalently 48 bits of the key are missing. WebThe key is hexadecimal. So every two characters makes up one hexadecimal byte, which brings the length down to 32 actual bytes. There are 8 bits per bytes, so 8*32 = 256.
