Sometimes you may face a situation where your family forgot the password of their archived backup files, And ask you to unlock their valuable files. Here we show you different ways to do so.
Getting ready to crack the passwords!
1. Always consider the risks, You should either download an application or use an online service to do so. Generally, free downloadable applications are only capable of recovering short and known passwords. Do not trust the free application that claims to uncover very long passwords as they could be malware. Recovering archive passwords are rarely possible!!
2. if you want to use an application to crack the RAR or Zip passwords, you should close all other apps running on your machine to optimize the resources (especially CPU intensive work).
3. Decrypting password-protected archives may take a very long time depending on the computing resource available and complexity of password. If you stumbled upon a software that offers to unlock files with long passwords within a few seconds on a weak machine, that software could be a malware.
For example, if an Android App is advertised to crack large and complex passwords on a low-end mobile phone, then this is likely a scam.
The Free Software Way
