Key Space: In cryptography, key space refers to the set of all possible keys that can be used with a cryptographic algorithm, defining the limits of potential key values. The size of the key space (i.e., the total number of distinct keys) is determined by the key length, impacting the algorithm’s resistance to brute force attacks. For example, a 128-bit keyspace has 2^128 possible keys.
