Key Length

Definitions

1. The size of a cryptographic key, usually measured in bits, which influences the search space an attacker would face in brute-force attempts. Key length matters, but security also depends on the algorithm, mode, implementation, and how the key is managed.

   In plain English: How many bits long a cryptographic key is.

   Example: "The vendor increased RSA key length, but the bigger issue was that private keys were still stored insecurely."
