Hello Mikiya,

So thank you for writing this tool! Quick question on the GUI version. I specify the source and destination paths, but I cant see where to put in a password or to kick off the decryption.

This is what it looks like for me:

Hi
Create an empty file named "resizeEnable" where your jar is located or simply start it with "r" option : "java -jar GUI_JAR_PATH r". You should be able to resize the window, it can happen when Java cannot properly detects your screen size or your resolution is not commun.

Hello,

I tried to decrypt some files I downloaded from my AWS S3 and previously uploaded there with Hybrid Backup Sync and its client side encryption using Hybrid backup Sync Decipher 1.5.1 but so far unsuccessful.

When I use the GUI I get the error message "All files fail to deciphered" and the report says the following:

Files in success for decipher operations in Hybrid Backup Sync utility :


----------------

Files in error for decipher operations in Hybrid Backup Sync utility :

/Users/netznutzer/QNAP/song.mp3


When I try using the Terminal after entering the password it says "The file song.mp3 is not a QNAP-ciphered file.", however it absolutely is one.

I only recently installed Hybrid Backup Sync on my QNAP and so far just uploaded a few files with it for testing. I'd like to use it in the future for backing up all my files but it must be with encryption and I would prefer having a way to still decrypt single files if I should need just one from the cloud. The version of Hybrid Backup Sync is 2.1.190329, maybe did some changes happen to the way it encrypts files?

Just to be sure I am not doing something wrong, I create a job to backup a certain folder to my AWS S3 and while doing it under settings I can set a password for the client side encryption which is all I did (didn't find any any advanced setting for example about which cipher or key length to use). Also I am absolutely sure I didn't enter a wrong password, I tested this now many times and uploaded more than one file. The encryption at least seems to work, I can't open them anymore when I download them from my AWS S3. Restoring them in Hybrid Backup Sync also works, just would be great if I could do that on my computer too.

Thanks in advance :-)

Hello
My tool is required only for "synchonization mode" to OneDrive, Dropbox, ect ...
When you setup a backup task in HBS to AWS, you use the "backup mode".
When you use this mode, you should be able to use standard "openssl" commands to decrypt your files (like first message of this topic).
Tell me if it's ok with this command.

Thanks a lot, the command in the first post worked, glad to know I have a method this way to decrypt single files without the NAS if I should need to :-)
By the way, is there also a GUI available to do these things with OpenSSL, in my case for macOS?

I'm currently working on my tool to be able to decipher files in "backup mode" too. As soon as i can get a beta version ready, i will update this topic :wink:
