Commands

The command FolderEncryptor.exe --help lists the available commands and FolderEncryptor.exe <command> --help shows more details for an individual command.

Command	Description
list	Descrpyt and list filenames.
enc	Encrypt the spesified target.
dec	Decrypt the spesified target.
analyze	Analyze the spesified target.

Usage

Simplest way to encrypt your folder is:

FolderEncryptor.exe enc --dir C:\input-folder --desDir C:\encrypted-folder 

For additional security we highly recomend the usage of --enc-filenames flag

FolderEncryptor.exe enc --dir C:\input-folder --desDir C:\encrypted-folder --enc-filenames

And to decrypt your folder:

FolderEncryptor.exe dec --dir C:\encrypted-folder --desDir C:\decrypted-folder 

If --enc-filenames flag is used then you must also provide when decrypting:

FolderEncryptor.exe dec --dir C:\encrypted-folder --desDir C:\decrypted-folder --enc-filenames

If you only want to decrypt and see the filenames:

FolderEncryptor.exe list --dir C:\input-folder

You don't need to set --enc-filenames flag since this command is already implies it.

Building

Prerequisite

• Visual Studio Version 17
• .NET 6 SDK

Road Map

• Option to securely erase unencrypted files. (looking at you Gutmann Algorithm 👀).
• Option to overwrite the original file to erase unencrypted data. (This may be not possible if --enc-filenames flag is set)
• Option to output a single encrypted file for whole folder (Something like gzip).
• A way to use the files without decrypting to file system first. (A Virtual file system might sufficient)
• When the structure and content of the tool is finalized, proper OOP standard must be used for the source code.

IMPORTANT NOTE!

When you encrypt your folder and than delete the old folder. Keep in mind that it can still be recovered! We are planning to include secure delete of the folder bu meanwhile you must use a 3rd Party tool for that such as Microsoft's Sysinternals SDelete for Windows 10 and up.
