key length 56 bits

A key length of 56 bits means the encryption uses a key that can have 2^56 possible combinations, which is over 72 quadrillion options. This level of complexity helps protect data because it makes it extremely difficult for hackers to try every possible key to break the encryption. In simpler terms, longer keys provide a stronger security barrier, making unauthorized access far more challenging. However, with advancements in computing power, 56-bit encryption is now considered relatively weak by modern standards, as it can potentially be cracked with enough resources and time.
