I failed due to having too complex a password. Here is what I learnt on the way, though.
- CherryTree encrypted databases are a 7z encrypted archive
So you need to crack the 7z archive. - Get the password hash from the 7z file
Use 7z2hashcat - Use HashCat to attach the password hash.
Why did I fail?
I used a long, complex passphrase, and the time to crack that is measured in years.
