TrueCrypt pass of lowercase letters and numbers

[skokov]

I forgot a TrueCrypt password of the cloud file where I store scans of my medical documents

I know I used most basic settings and just lowercase letters and numbers.
I find documentation confusing so can you please check if it will do all combinations lowercase letters and numbers until password is found?

cudahashcat64.exe docu.tc -m 6211 -a 3 --custom-charset1=?l?d

unless your password was only 4 chars or less don't bother with such a brute-force attack.

Unfortunately it was at least 8 characters.
What if I knew it was pattern like (L is letter and D is digit):
myDDDpassDDDwordLLL
DDD would be 1-3 digits and other text is known

it's so simply you will bang you head on the table. the masks you are looking for are:

my?dpass?dword?l?l?l
my?d?dpass?dword?l?l?l
my?d?d?dpass?dword?l?l?l
my?dpass?d?dword?l?l?l
my?d?dpass?d?dword?l?l?l
my?d?d?dpass?d?dword?l?l?l
my?dpass?d?d?dword?l?l?l
my?d?dpass?d?d?dword?l?l?l
my?d?d?dpass?d?d?dword?l?l?l

Thanks! This is simple and makes sense. Too bad documentation makes is hard to find.
10 days remaining for current mask... so undeath was right.
