Why KCV is 4 bytes if 3des encryption of a "zero block" yields 8? In other words - there is a mistake somewhere, you need to nail it down. Try a different online tool, check if the result is the same.. Try performing 3des as 3 single des operations one by one - wiki should give you the exact algorithm - it's easy. $\endgroup$ – tum_ Jun 29 DES Calculator The DES Calculator applet is used to encrypt or decrypt test data values using DES block cipher. It takes a 64-bit (16 hex digit) data value and a 128-bit (32 hex digit) key. It can optionally provide a trace of the calculations performed, with varying degrees of detail.
