Folder Lock: Securing your files with ROT-25

August 23rd, 2008 rbu 2 comments

According to the author the $35 Windows program Folder Lock is “a fast file-security program that can password-protect, lock, hide and encrypt any number of files… Protected files are hidden, undeletable, inaccessible and highly secure”. It even works on “USB Flash Drives, Memory Sticks, CD-RW, floppies and notebooks.”

Now while I still wonder how they protect files from deletion on USB sticks, Charalambous Glafkos found out that the password to encrypt the files is stored in the Windows Registry. For maximum security it is reversed and encrypted with ROT-25.
