Bruteforce + dictionary attack
#1
How can I perform attack like this:
1-10 length bruteforce attack using charset: alphanum + .
and prefix from a dictionary file?

I tried reading --help but it's not very readable.

you should be able to find the answer to your problem in the wiki https://hashcat.net/wiki/

I have this, but it doesn't work:

oclHashcat64.exe -m 0 -a 7 -o results.txt --outfile-format=3 -1 abcdefghijklmnopqrstuvwxyz0123456789._ ?1?1?1 prefixes.txt hashes.txt

WARNING: Hash '?1?1?1': Line-length exception
#4
Ok, I changed to:
cudaHashcat64.exe -m 0 -a 7 -o results.txt --outfile-format=3 -1 abcdefghijklmnopqrstuvwxyz0123456789._ hashes.txt ?1?1?1 prefixes.txt
and the error is diff, so I guess this thread can be closed
