If it’s your archive — short checklist:
- Try likely passwords, backups, older copies, or the app/version that created it.
- If that fails, use a recovery tool: commercial (Elcomsoft/Passware) for ease, open-source for DIY.
- DIY steps (advanced):
- rar2john file.rar > hash.txt
- hashcat -m 12500 hash.txt -a 3 'My-Password-?d?d?d?d'
(use
-m 13000
for RAR5).
- rar2john file.rar > hash.txt
- Use masks/wordlists to narrow the search. GPUs speed it up.
- Only attempt on files you own — don’t try this on others’ archives.
