Why is this DES key considered weak?

2021年6月11日 — First, DES keys are considered to be weak because they are only 56 bit keys giving only 256 possible keys. That small of a key space is ...

Can you explain “weak keys” for DES?

2013年12月8日 — Another types of keys called semiweak keys are one which repeat with a period of two. Due to the way in which DES generates subkeys; instead of ...
