Subject: Different results with multiple salts in a file
I'm running into a weird issue when running a simple wordlist mode
session and the hashes don't all have the same salt. If I run a crack
against a single hash, or hashes that all have the same salt for known
weak passwords, john cracks them. When I put the same weak password
hashes in a file with that contains hashes with other salts, none of the
known weak passwords are cracked.
example sessions:
./john --wordlist=wordlist.txt singleHash.txt (successful)
./john --wordlist=wordlist.txt multipleHashes.txt (fails)
./john --wordlist=wordlist.txt --salts=2 multipleHashes.txt (successful)
single hash file contains:
toto:0x01004086CEB6BF932BC4151A1AF1F13CD17301D70816A8886908
multiple hashes contains:
toto:0x01004086CEB6BF932BC4151A1AF1F13CD17301D70816A8886908

I think john should be able to crack the known weak passwords even when
there are multiple salts.
I'm running john-1.7.6-jumbo.
Thanks,
Zach
