sha1 salt question - forumhero - 11-23-2011
this goes back to the geocaching thread that's been closed but i still had a question left unanswered. atom said there were a few ways to crack the salted hash but when i tried it using the hash
alt format it didn't work. here are the examples:using sha1($pass.$salt) fails to return plain text
Code:
oclHashcat-lite64.exe -m 101 8882caa3b88a5a16fad6287e26d8a8f9454ad643:PEPPER "N51 03.?d?d?d W114 07.?d?d?d"

Device #2: Cypress, 1024MB, 0Mhz, 20MCU
Status.......: Exhausted
Hash.Type....: sha1($pass.$salt)atom's way using the salt as part of the mask itself and it works
Code:
oclHashcat-lite64.exe -m 100 8882caa3b88a5a16fad6287e26d8a8f9454ad643 "PEPPERN51 03.?d?d?d W114 07.?d?d?d"

Hash.Type....: SHA1shouldn't it work in either case?
RE: sha1 salt question - atom - 11-23-2011
why should that work? sha1($pass.$salt) is not sha1($salt.$pass)
RE: sha1 salt question - forumhero - 11-28-2011
understood, please excuse the ignorance as i wasn't sure which was the proper algorithm to use given the known hash and salt.
