AxCrypt .axx files

[TomM]

Hi

I have some old .axx files encrypted with AxCrypt. I think AxCrypt 1 rather than AxCrypt 2. 

I don't know the password and don't have any pointers such as number of characters, or mix of characters used. However I always use at least 12 characters so probably did the same here.

Is it possible to decrypt these files using Hashcat?

If so, how would I go about this and how long is it likely to take?

Thanks
