No… It reduces the boiler plate code and easy to configure and build extension.
You can take a look at the repo for the project structure and configuration.

We can encrypt pdf, mp3 and video mp4

9

Yes, you can encrypt any file type.

10

When file name put and click on encrypt then show msg no such file.
What is the file path?
Please reply

11

Can you show me your blocks? So, I can see if there’s anything wrong with the path format.

12

Actually we try with your apk which are you given in this post.

The path can be specified like either /storage/emulated/0/Downloads/sample.pdf or /Downloads/sample.pdf if UseAbsolutePath property is set to false.

I’ve been recently working on this extension and planning to move it out from the BETA stage. I just created a new test app to encrypt/decrypt files for testing. I’ll update the main post soon once I make it async ( currently freezes ui ) and the key issues. If you want to test it. Here you go.

Extension ( 1.2b ) : com.jaxparrow.filecrypto.filecryptography.aix (6.8 KB)

Test apk : File_Crypto.apk (5.5 MB)

I installed the app and found that no file is being encrypted, the output is from the blank, please rectify it, I need it very much thank you

is there any size limit bcz i want to encrypt 2gb approx movies

17

It’s been a while since I’ve worked on it, and it’s still SYNC ( runs on a single thread and will freeze the UI ). That’s why I haven’t moved this from the beta phase ( haven’t got any time to work on this ), will patch things up soon.

and I don’t think this would be an efficient way to encrypt a 2GB file.

18

is there any way to encrypt a video to many parts with a .exo extension

I am waiting for new update
