how should i crack this type of hash (sha1 & salt)

[philsmd]

you are NOT allowed to post hashes. read the forum rules. You will get banned by not following the rules.

As far as I understand, you are saying the algorithm is basically:

Code:

echo -n --74e3c24fd83d92ea72383e9b3a4292bdfb8eb174--secret88-- | sha1sum

so you must use -m 120 with a salt of "--74e3c24fd83d92ea72383e9b3a4292bdfb8eb174--" (without quotes):

Code:

hash:salt

where salt is --74e3c24fd83d92ea72383e9b3a4292bdfb8eb174--

furthermore you need to apply the rule: $- $-
i.e. the append rule function is used twice to add both of the dashes

append_two_dashes.txt:

Code:

$- $-

Code:

hashcat -m 120 -r rules/best64.rule -r append_two_dashes.txt hashes_with_dashed_salts.txt rockyou.txt
