    Thread: How Calculate GPU Cracking Time
Post: RE: How Calculate GPU Cracking Time

The best way to do this is to perform an actual run. Raw wordlist mode (with no rules) is very, very fast. hashcat's guessing speed is so fast that it can often spend more time caching a large dict...

Post: RE: Generated wordlist size is not right?

You're right - I'm running it against a single hash, and I get the number you're expecting: Code: -- $ cat myowncharset !@#$%^&*? $ ./hashcat -m 5500 -a 3 -1 myowncharset -2 ?1?l?u?d test.h...

Yes, UTF8 is probably fine for WPA2 entered via a web interface. It sounds like you have the rest of the basics covered. Good luck!

You can use the --hex-charset option to specify this set of binary. Edit: specifically, something like: --hex-charset -1 000102030405060708 ?1?1?1?1?1?1?1?1 ... or however long your expected string...

Have you looked into hashcat's rules and masks? You may be able to significantly reduced the size of your wordlist, in exchange for faster coverage of your likely password space. For example, if your...

You said your CPU was better than your GPU. This is not correct. Your GPU is much better. How much RAM you're using only matters when using large lists of rules, etc.

Also note that the "maximum power" you mentioned early is memory size, which has no relationship to speed.
