# example command
hashcat -m 500 -a 3 -1 ?l?u?d -o cracked.txt hashes.txt ?1?1?1?1?1?1?1?1?1 -O

# -1 ?l?u?d
# this defines the custom mask
# ?l (lowercase alpha characters)
# ?u (upperacse alpha characters)
# ?d (digits)
# so this matches [a-zA-Z0-9]

# after the hashes.txt is the mask to use for each character guess
# ?1?1?1?1?1?1?1?1?1 indicates it should use the custom mask 1 for
# each of 9 characters.

using both my GPUs 1365.4 kH/s
CPU only provided about 50 kH/s

9 character password 645 years estimated to crack... yeah I don't think I'm going to wait that long... next idea
