hashcat Forum

Hello

I have a hash and its corresponding unhashed value.
I tried to put the hash into hash identifiers, but no luck, I do not know what the hash is.
I tried online identifiers and hash-identifier in The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) linux.

Is it possible for hashcat to identify the hash?
Is it possible to had hashcat the hash and a text file with the unhashed value, and hashcat is able to identify it?

Sort of. Put the passphrase (unhashed value) into a text file called words.txt in the hashcat folder

hashcat -m XXXX -a 0 yourhashvalue words.txt

Go through all the supported types (XXXX above) until you get a hit. Obviously try and match the hash with the right length to be in with a shot first too.

E.g.:
SHA-1 hash of blahblahblah is 25f683212e147aad3a11a8dd89b8de988be57349

Code:
hashcat64.exe -m 100 -a 0 25f683212e147aad3a11a8dd89b8de988be57349 words.txt

The wordlist or mask you are using is too small.

Therefore, hashcat is unable to utilize the full parallelization power of your device(s).

The cracking speed will drop.
