Hi All,

Got a quick question about cracking password I have noticed online there are lots online password cracking sites.

Every time I try supply a hash I get error saying its not a Hash I just want to make sure I was passing the correct thing to the site.

for example take this hash
root:$1$3OF/pWTC$lvasdl74pAHAcrvepWqpu.:12859:0::::: what would be the hash ?

As lordcranius mentioned, the password hash ends at the first colon (the password may or may not include a period but should be included if you're extracting just the hash). In the example you provided, the password hash is
$1$3OF/pWTC$lvasdl74pAHAcrvepWqpu.

Here's a useful link to that explains the format of the shadow file and what each field represents:

I hope you guys aren't actually posting hashes for a customer or anything important on a public web forum
