Speed questions

[edmund]

Hello Guys,
What can I expect of the time needed to crack a hash.hc2200 if the password consists of 8 characters being uppercase and/or numbers.
hashcat -m 22000 hash.hc22000 -1 ?u?d -a 3 ?1?1?1?1?1?1?1?1
Any real results with different video cards?

Suppose in this case it is not cracked, is it possible to extend the search with more options and at the same time 
exclude the previous search in order to save time?

If you're asking questions about how long it would take to crack a password you should be looking at benchmarks. They are all over this forum.

Just do the math, you have a password consisting of 8 characters which has 26(u)+10(d) possibilities. So 8^36 is your total possibilities and then look at benchmarks for relating to what kind of speed to expect.

Suppose you don't find the password, hashcat doesn't care whether you have guessed that password previously, its for the user to figure that out. If you're trying to crack wifi passwords, just look online for default passwords on your local marketplace, build a keyspace and minimize your workload as much as possible. It's easier to attempt 20 short attacks than 1 big long attack.
