What it calculates

Reports key length, byte parity, component relationships and applicable KCVs.

Inputs and methods

8/16/24/32-byte HEX key. Analysis includes all eight KCV variants when the key length permits them.

Worked example

Enter 0101010101010101.

8 bytes / 64 stored bits
Parity: Odd
Distinct byte values: 1
DES KCV: 8CA64D

Specification and limits

Length does not identify an algorithm or certify strength. This is not exhaustive weak-key screening.
