DES-ECB Numeric Key Search - Room641A - 08-03-2017
I was wondering if I could conduct a numeric only search when using -m 14000 instead of searching through the entire keyspace?
Test Example (DES-ECB):
Key: 6891082025701013 (randomly made up)
PT: 4B0A161F0BAB3CD4
CT: B384B7B51C1D5073
If I run -m 14000 (CT
T) -a 3 -1 charsets/DES_full.charset --hex-charset ?1?1?1?1?1?1?1?1 -o cracked.txt -w 3, it is telling me it would take 3 weeks for a 100% search.If I know the test key only uses numeric values that cuts the variables to 50^8 vs 128^8, a huge difference.

just use -1 charsets/DES_special/DES_numeral.charset

I am missing something. It's exhausting too quick with no results and the candidates #1 and #2 do not look correct. My hash is correct and it is my key so I'm right on my variables.
I'm using the following for my command line:
-m 14000 [ct pt] -a 3 -1 charsets/DES_special/DES_numeral.charset ?1?1?1?1?1?1?1?1 -w 3
If I replace the DES numeral charset with the DES full charset and add --hex-charset it launches fine. Is the mask defined differently for the DES numeral charset?
Thanks for your reply.

you still need to use --hex-charset also for charsets/DES_special/DES_numeral.charset since the charset is in hexadecimal format
