I saw a video on youtube from computerphile where hashcat was demonstrated, and it really does look like this tool might help me out.
My problem is that I have 1 truecrypt file of 80GB where I have forgotten my password - I know pretty much how many characters I used and what letters. My second file is a 7-zip file, here to I know what passwords I used however I have added a ! or a . somewhere and I cannot seem to get it open.
I have understood that the truecrypt file I extraxt a hash with another tool, same goes for 7-zip so my questions are related to hashcat command line. Lets assume I have saved the has in a file called hash.txt which is in same directory has hashcat, hopefully this opens up for a easier to understand command line if you can help me
So I have 2 questions:
1. Truecrypt file
I wonder how I run hashcat to try passwords in 5-10 length containing a-z and a possible single or double ! or . in the end. That is - [a-z!.] as character base, 5-10 chars only. Surely check for capital first letter aswell I guess sounds reasonable. What would the command line look for this?
I have the hash in my hash.txt fil, what would the setup for hashcat here be and what would the command line look like to do the above?
2. 7-zip file
In this case I have some 7-8 passwords I remember in my head and I sometimes combine theese into longer strains adding some numbers or punctuation at the end. I know now - not very secure. However, say that I know in this case the password is a combination of the following (example passwords seperated by comma).
Password used : pizza, stop!, burder, Hallo!, 020675
How do I setup hascat to combine the above passwords in all possible combinations pluss adding ! and . in the end aswell. Also, all passwords could be checked with capital letter first and last.
In my password list above I have 5 passwords in total, my lost password for this 7-zip file could be a combination of 2 of them, or 3 or 4 I do not really remember so I would need for hashcat to try combining it all.
I have the hash in my hash.txt fil, what would the setup for hashcat here be and what would the command line look like to do the above?
Is this what hashcat is for, if so I am in luck.

I hope anyone here have some time to help me out here, and please ask if something is unclear in my questions.
