Manual Decryption of Hybrid Backup Sync file

[Mikiya]

Erf yes it seems ok...
Try to use "D:\Downloads\hybrid_backup_sync_decipher_1.4.2(1)\IMG_0195" ? (it should be the same as ".\IMG_0195" but it's to be sure ...)

Hey Mikiya

I was typing the command wrong and the program deciphered the file but the movie file still won't play

I'm not sure whats going on with this.

[techguy12]

also when I try a txt file, the words are just symbols -_-

[Mikiya]

When you deciphere the files (txt or movie), choose a different name or a different location for the output (deciphered) file, not the same as encrypted file.
-i ".\IMG_0195" -o ".\IMG_0195_plain" for example.
The tool should add "_plain" automatically if you don't do that, but it's better to add it manually. If you do not see "IMG_0195_plain" after the operation, the process had failed. The tool never overwrites the source (encrypted) file.

hey Mikiya

I was able to get it to work!!!! THANK YOU!!

I really wish that QNAP gets on this and apply a solution to do this automatically de-ecrypt when downloading via HBS

What was the problem ?

I just try on my W10 computer :

Code: Select all

java -jar hybrid_backup_sync_decipher_1.4.2.jar -v -i "new 3.txt"  -o "new 3.txt"

Code: Select all

java -jar hybrid_backup_sync_decipher_1.4.2.jar -v -i ".\new 3.txt"  -o ".\new 3.txt"

works.

Try the graphical version, if you encounter problems, tell me. If a patch is needed in some "weird" situation, i can take a look at it.

PS (quoted from Github wiki as remember for every one) :

Note on files choices: you can choose a folder as source or destination.
If a folder is chosen as source, the destination MUST be a folder too.
If a folder is chosen as destination but the source is a file, a file with the same name will be created in destination folder.
If the source and the destination are the same file or folder, a new file will be created, with same name prefixed by "plain_".

The issue for me was that I didn't put the file type at the end of the name. Instead of putting .\IMG_0195.mov, I was putting .\IMG_0195

and for the GUI, all it shows is this--->https://gyazo.com/ddbdd09de5633b0770a6a40b020eb9e1 and when I open the txt file--->https://gyazo.com/a48fb08881825f14f0f131076f276c84

if you need me to test some more with other files, please let me know and I'll be more than happy to help

Hello
Can you try this version : https://yoann-tritz.fr/documents/hybrid ... .4.3b1.zip ? I try a small workaround based on this problem : https://stackoverflow.com/questions/919 ... ile-exists
With the same methods as before, and now you can also start GUI with command line :

Code: Select all

java -jar hybrid_backup_sync_decipher_1.4.3b1_gui.jar v

The new option "v" enable log in command prompt for the GUI version.

[techguy12]

Hey

Running that command does open the GUI version and works for me on my test file

Question, does this version also decompress while de-encrypting the file? if compression AND encryption was selected within HBS

[Mikiya]

Hey
Good news !
And does it work if you just "double click" on hybrid_backup_sync_decipher_1.4.3b1_gui.jar and try your files ?
Yes decompression should be done since v1.4.

Hey Mikiya

Yea it does Thank you so much for your entire help with this!!!!!!!!!

[Mikiya]

Glad to hear that !

For those who like me want to decrypt files on the Android smartphones can try the mobile version of Mikiya's tool here .

Thanks again for your work on this project, your app is cool and can be useful !
