My practice attempt to decrypt a SHA-256 hash of an IP address
#3
royce,
thanks for the answer!   I still have 2 questions:
  1.  your pastebin sample I am not understanding why you provide me with a 600 line file?
  a.  I tried and I got a match with this (in under 1 minute??) :   ?d?d?d.?d?d?d.?d?d.?d?d?d .  (3d.3d.2d.3d to match my sample ip: 208.187.32.155)?
  b.  how do I change this parameter to match 1-3 digits in each part of the ip address?
c. I tried using --increment but it didn't work . (perhaps my syntax was wrong? i was expecting each custom defined charset to be incremented 1-3 times) : hashcat ./hashedIPs.txt --outfile-format=2 -o outfile.txt -m 1400 --custom-charset1=?d?d?d --custom-charset2=?d?d?d --custom-charset3=?d?d?d --custom-charset4=?d?d?d --increment -a 3 ?1.?2.?3.?4

  1. 2.  Not understanding your CPU suggestion: there is no mention of CPU/GPU in the  'hashcat --help' .  I suppose perhaps I may be using GPU if my CPU only looks like 1 core is running?
