DES KPA
#1
I was wondering if it was possible to crack DES KPA generated the following way

Code:
#echo -n "1234567" | openssl enc -e -des-ecb  -a -nosalt -k a
KQxly2BIRZo=

#echo -n "KQxly2BIRZo="  | base64 -d | xxd
00000000: 290c 65cb 6048 459a                      ).e.`HE.

I was also looking at crack.sh but it requires a plaintext of 8 characters. And I don't understand this further.

Code:
#echo -n "12345678" | openssl enc -e -des-ecb  -a -nosalt -k a
Fgzr30dX4WjdSY+WC4uZfg==

Can someone help me understand this.

I misunderstood the plaintext part. It uses PKCS7 padding in my case.
That solves my issue.
