* Synopsis: Folder Lock 5.9.5 and older versions are prone to local information-disclosure vulnerability.
* Successfully exploiting this issue allows attackers to obtain potentially sensitive information that may aid in further attacks.
* The security issue is caused due to the application storing access credentials within the Windows registry key:
* (HKEY_CURRENT_USER\Software\Microsoft\Windows\QualityControl) without proper encryption.
* This can be exploited to disclose the encrypted _pack password of the user which is ROT-25 and reversed.
*
* Sample Output:
*
* ASTALAVISTA the hacking & security community
* Folder Lock <= 5.9.5 Decrypter v2.0
* ---------------------------------
* Encrypted Password: :3<k_^62`4T-
* Decrypted Password: ,S3_15]^j;29
