Encryption is working well.
But I can't open the exe file inside the virtual drive by dokan.

Environment:

• Windows 11
• Visual Studio 2019
• 64-bit, Release build of cryptopp-CRYPTOPP_8_6_0, EncFSy_lib, and EncFSy_console
• Dokany v1.5.1.1000

Exception thrown:
The following exception is thrown when I open Microsoft Visio file from Mounted Drive.

Hello,

I was just trying to compile Encfsy with VS2019 and it seems that it needs SDK 143 which does not come in that version, but I think is available in VS2022.

Can you please tell me what version of Visual Studio you used?

Also, I am seeking someone who might be interested in working on a C++ SSHFS version that can compile under the latest Dokany. I have seen that there is a C# version available, but I am seeking a C++ version.

Would you be interested?
Thanks

EncFSy_console fails to run as it require some configuration file. It would be awesome if a sample configuration file in included in the encfsy repository. Right now, application just exit with code 1 just after entering password.

When I copy a large file to EncFSy drive, the copy operation takes too much time (around 5-15 seconds) while estimating Time remaining as can be seen in the screenshot given below.

I noticed that the copy operation starts instantly when I copy the same file to an another partition or Cryptomator or Boxcryptor drives.

Would you be please kind enough to tell me why you encrypt the tail of the file two times in streamEncrypt function?

The size_t is unsigned int whose max value is UINT_MAX = 4294967295 = 4.3 GB which means maximum file size can be around 4.3 GB only.

Isn't it a bug to use size_t instead of long here?

Currently EncFSy encodes both directory and file names. I have come across a need to disable directory names encoding. It would be so wonderful if you please add this feature in EncFSy.

Note: Sample corrupted image & steps to reproduce the issue are mentioned in the second comment.

I found that Mutex destroyed while busy exception occurs if I open a corrupted image file in EncFSy Virtual Drive.

The exception occurs on delete encfsFile; line.

Visio file gets corrupted if it is saved after relocating an existing component i.e. rectangle, circle, square, etc.

Steps to reproduce:

• Create a Visio document, place in it some components i.e. rectangles, squares, circles, etc. then Ctrl+S to save and then Close it.
• Reopen the same document, which it does open successfully, however move and change location of an existing component and then save and close it.
• Now again try to open the same document, but, unfortunately this time it would not open, instead Visio will show this message:
  

I use Microsoft Visio 2019:

(Please read 2nd comment and 3rd comment to know why I want this)

Can you please show me how can I add 2048 Bytes File Header to every file that is created in EncFSy with UniqueIV set to true?

For the time being, I write 2048 Zeros if they are not already written and then set off to off += 2048 before passing to the following write function in EncFSWriteFile callback function:

int32_t writtenLen = encfsFile->write(FileName, fileSize, (char*)Buffer, off, NumberOfBytesToWrite);

But this does not work and the EncFSy throws exception.

I look forward to your help please.

[Attached 3 Screenshots below]

I have a folder containing around 100 PNG image files, when I open that folder and quickly scroll down and double click on an image to view it then the EncFSy crashes. Stack trace attached below.

I have also reproduced this issue by trying to open too many images quickly.

Note: It takes a bit patience to reproduce this issue.

Just installed it , dokan is 1.5.1.1000, but the encfsy complaints "Can't assign a drive letter" , no matter if I run this on gui - even as "admin". (windows 10 21H2 x64 )

It would be so awesome to warn user if there are some opened files, e.g. Word document, before unmounting EncFSy Drive.
CppCryptFS handles this very nicely by counting the Files Handles and the same can be implemented in EncFSy.
