DES-ECB brute force - khadige - 02-01-2018

Hi
I experminting with DES brute force in hashcat but none of the commands below resulted in to finding any key. I should mention that all plaint-text/cipher-text pairs has been checked with openssl encrtyption tool.
What is the problem?



Code:
./hashcat64.bin -m 14000 47dc9810ade39295:b5866d1dd5cdf934 -a 3 --quiet --hex-charset 6861736863617431 --outfile-format 5 --potfile-disable

./hashcat -m 14000 3636363636363636:37f8759eb77e7bfc -a 3 --hex-charset 3636363636363636 -1 charsets/DES_full.charset --quiet --potfile-disable

./hashcat -m 14000 3737373737373737:5013CA4F62C9CEA0 -a 3 --hex-charset 3737373737373737 -1 charsets/DES_full.charset --quiet --potfile-disable

./hashcat -m 14000 3838383838383838:8940F7B3EACA5939 -a 3 --hex-charset 3838383838383838 -1 charsets/DES_full.charset --quiet --potfile-disable

what is the string after "--hex-charset" supposed to be? What is the key for each of those ciphertexts?

Your hash is formated wrong. See here:

Code:
root@et:~/hashcat# ./hashcat -m 14000 b5866d1dd5cdf934:47dc9810ade39295 -a 3 --quiet --hex-charset 6861736863617431 --outfile-format 5 --potfile-disable

Thanks for your response.
The string after "--hex-charset" is the correct key.

You just have to switch:

b5866d1dd5cdf934:47dc9810ade39295

to

47dc9810ade39295:b5866d1dd5cdf934

Thanks a million!
