Easy for you, hard for me - mask writing

[mastercracker]

How is it possible to instruct one place to guess all uppercase and lowercase letters? Also, how to instruct to first guess 7 letter passwords, then 8 letter passwords, etc.? I see the password min and maximum flag there in the help file, however I am not sure how to use it. Thanks again.

I strongly suggest that you read the wiki at hashcat.net/wiki. Every answers to your questions are there.

1) You can use -1 ?u?l and use the mask ?1crossa7?a which will look for every upper and lower case on the first position.

2) -i with --increment-min=7 or just create 2 masks: 1 of length 7 and 1 of length 8.
