WebThe key space is the set of all possible keys. With symmetric ciphers, where any string of n bits is a valid key, the key space has 2 n elements. With asymmetric ciphers, it's more complicated. With monoalphabetic substitution ciphers, you have 26! keys, but key length depends on how you're expressing the key. WebFeb 24, 2024 · This means that a byte can be expressed as two hexadecimal values: Take a byte value e.g. 0b10110011 and split into halves: 0b1011 0b0011. Convert each half to decimal (if you can’t go directly to hexadecimal in your head): 11 3. Convert each half to hexadecimal: 0xB 0x3. Squish halves together: 0xB3.
