description

we got this corrupted hash password from a Pcap file with a note (password = sha-1(hash-result)).

HASH:77be5d24ed2e3e590045e1d6o7e84i50d2799c19f48ede46804a8734e287df120f

Solution

we look on the corrupted hash ⇒ 77be5d24ed2e3e590045e1d6o7e84i50d2799c19f48ede46804a8734e287df120f, so it seems to be maybe 64 characters (We have more letters),well let's say the hash is (SHA-256) , well the hash SHA-256 only include from 0 to f , yeah We now know the two extra letters, which are: i and o after remove them hash will be ⇒ 77be5d24ed2e3e590045e1d6o7e84i50d2799c19f48ede46804a8734e287df120f

we will use this site to decode it ⇒ https://www.dcode.fr/sha256-has

and we know the password = sha-1(hash-result),so we do it in same site :

flag

done 🎉
