I think of adding a translation system, were you can switch the language. Some people dont understand english very well and may like it in their language

As you explained here(#19) how the get the key from rpg_core.js file. I opened rpg_core.js file in the workpad, use the search option (Ctrl+F) and search for "Decrypter.readEncryptionkey" in the file however, I get the result as this:

Decrypter.readEncryptionkey = function(){
this._encryptionKey = $dataSystem.encryptionKey.split(/(.{2})/).filter(Boolean);

So I could not get the key. And as you can understand I am not good with coding etc.

Note that I tried the system.json detection tool first.

Thank you in advance

Hello there. There is problem with this game. https://nemlei.itch.io/the-coffin-of-andy-and-leyley
I tried using your site, to decrypt PNG, but they are not open properly.
I tried to find Decryption code manually in system.json (find d41d8cd98f00b204e9800998ecf8427e but seems code is "fake") and in rpg_core.js (find Decrypter.readEncryptionkey = function(){ this._encryptionKey = $dataSystem.encryptionKey.split(/(.{2})/).filter(Boolean);)
Gonna send also system.json and rpg_core.js

files.zip

I hope you can help me)

Im not sure if its supposed to or not, but unlike the other versions of the rpgmaker decryptor programs, this one doesnt extract the .rpgmaker project file with which you need to open it in rpgmakerMV program?

hey man could you please update your tool ? It doesn't detect Decryption-Code anymore.

I cannot decrypt stranger of power 2 resources , help with the file if you can or help me to decrypt it if you can. I no sure if i done something wrong or wha. Do help to check it thank.

I tried to decrypt a bunch of Files for someone but I saw that my Firefox (on Fedora 26) freezes if I try to Download the Files as ZIP... So I have to investigate why

I hope you will add the ability to open files from google drive ;save decrypted images and audios and save all as a zip directly to Google Drive

it told me that "Please try to select the rpg_core(.js) file and try again"
but it also told me that "Error: File-Content was invalid (Was not a JSON-File)"

I was planning to re-encrypt some files because I was making a custom sprite mod for a game called OMORI, but the .JSON file (which is in www/data) has been set to a custom file extension (named after one of the characters) .KEL. I've had a search around and I don't think I've found any mention of a way to do this on RPG maker forums so this might be an individual thing, but I thought if anybody knew about encryption of RPG maker files it'd be the guy who made this. I tried just putting it in, but it just comes out with an "it's not a JSON" message.
Do you know any way to get this in a working .JSON format? I tried literally just changing the file extension but it comes out unreadable (unsurprisingly). Is this impossible to get working? Or am I being a moron and there's actually a super obvious fix to this?

If someone has the Opera Browser, please tell me if it works. It would be super kind of you

(If not, please be detailed what doesn't work etc)

I found it is less efficiency to click and select only a single file each time, is there any way to decrpyt all files in some directory, and it would be better if support command line.

I selected the System.json file, after click detect button , this showed up:
'Error: File-Content was invalid (Was not a JSON-File)'
Why? I ' m pretty sure that i choose the right .json(www/data/system.json)

Vodka, Putin, Balalayka. Hallo.

I tryed v1.0 on 900-1000 (of 1900+) files (1.1+ GB). Chrome tab crashed (64.0.3269.3 dev).
But 800-850 files works fine.
FF works fine making archive of all 1900 files

Can smb test this case? Dev? (:

I can't seem to view decrypted image files decrypted from rpgmvp for some reason

When I try to convert the rpgmvo file, (Audio file) to .ogg, then it won't even let me, because when I open the file system, it says 'No items match your search.' I tried it with both of the 'choose your file' Buttons, and no, I didn't delete them. I checked afterwards. Help would be appreciated.

So, as far as I understand it, the files are formatted like this:
Bytes 0-15: RPG Maker MV header.
Bytes 16-31: The first 16 bytes of a file XOR-ed with a 16-byte key shared across all files in the game.
Bytes 32-...: The rest of the file.

Currently, this project supports recovering PNGs without the key, as well-formed PNGs are guaranteed to have the exact same first 16 bytes (89 50 4E 47 0D 0A 1A 0A 00 00 00 0D 49 48 44 52).
However, this can easily be leveraged to recover the original XOR key, since plaintext XOR key == ciphertext, but also ciphertext XOR plaintext == key, and we have both the ciphertext (the "encrypted" bytes 16-31 of an encrypted PNG) and the plaintext (those constant first 16 bytes of a PNG).
And since the key is shared, users could be directed to decrypt a single .rpgmvp from the game to get the key, which they can use for any of the rest of the files.

oh hi, i thought of decrypting a game, however the only game files that are visible are the .exe and the save file in www/save/persistent.rpgsave
is it still possible to extract game files from something like this?

I'm pretty sure it is an RPG Maker MV game, because the exe has this icon

I want to increase the performance in terms of memory a bit more by using let and const instead of var

I've got an E-Mail of somebody who get only cryptic stuff as decrypt-result. It seems that the file is decrypted but the header is messed up.

I asked for files to reproduce the problem but for me it was decrypted like normal. Maybe some other have the same issue please tell me here!

The bad result look like this:

Nothing is working. Unfortunately, all of the decrypted files contain errors.

Can't view the Files in Edge-Browser...

I ran across a game with webp files. In this case they were not encrypted, so there's no actual issue with that one, but it is possible or perhaps even likely that in the future there will be more games using webp instead of png. The image decrypter seems to not want to work with webp files (in fact, it doesn't even list them in the open dialog) so this could be a potential problem in the future. This is more a heads-up than anything else, but it does make sense that it should support webp anyway.

If someone has a Safari Browser, please tell me if it works. It would be super kind of you

(If not, please be detailed what doesn't work etc)

i've used the site before, it worked great
but this time it's just simply not working, and i'm doing everything the same as i did before

i used it to extract sprites from the coffin of andy and leyley in the past, and it worked but it's not now :( it seems someone else also had troubles extracting from this game recently

i'm on a macbook pro, and i tried using both chrome and firefox if that matters

Hello,

I tried to decrypt this file using the system.json code - 90b329161632b112351d264196c31dad
However, the image cannot be viewed. Here are the .json, .js and the .rpgmvp

Any ideas that might work?

Thanks.

As you can see by the screenshot, the option to encrypt files is greyed out so is it disabled for some reason?

Because, on the website, there's no issue encrypting files.

Should I add the "How-To-Use" content in a Spoiler like "Browser-Support"?

More people go and try to hide their Keys inside the rpg_core.js-File

I want to add a function to analyse this file as well

I noticed that several Games starting to use the LZString compression to make it a bit harder to get on their Data... But its simple just an other useless method which can be uncompressed really easily!^^

I wrote a quick uncompressions Tool for that: http://petschko.org/tools/unCompressLZString/

But I want to add it to the function, which checks the System-JSON for the key. So that user don't have to mess with that

Edge decrypts the image correct and also download it. The only problem is, that it changes the extension to ".txt".

After renaming you see the correct file. But its not very nice renaming every file

I'm trying to pull the music files from OMORI, and the encryption key is in .KEL file format. How should I turn the .Kel file into JSON format?

Same as here but for the JS-Version:
Petschko/Java-RPG-Maker-MV-Decrypter#4

Sorry to bother you, but I ran into some issues that you've already solved. This may be related to my inexperience in the program, but I would like to ask you to help me solve it.

Decrypter.readEncryptionkey = function(){
this._encryptionKey = $dataSystem.encryptionKey.split(/(.{2})/).filter(Boolean);

I can't find the Decryption-Code in System.json, probably because the author hid the code. so I added your code at the bottom of rpg_core.js according to the method shown on your website.

But nothing changed. I opened the game, and after closing the game, I didn’t find the Decryption Code anywhere, and there was no change in rpg_core.js.

The game is called Evering chp 1

can u help me? i could not do it

When I unpack this game, it just outputs game resource files that can't be used, including audio and picture files. Everything can't be opened normally.

I'm unsure it's a bug or not but whenever I restore an image file and click view it will always open another tab full of moon runes. Downloading the img works fine but I don't want to download the imgs sometimes

i was trying to decrypt omori since I wanted to have the bgm/sound effects for my own use, however I couldn't find a decryption key... i don't really know anything about coding myself though, so maybe i just don't know where to look but all i've found so far was this:

Decrypter.readEncryptionkey = function(){
this._encryptionKey = $dataSystem.encryptionKey.split(/(.{2})/).filter(Boolean);
};

since the game is paid i don't really feel comfortable reuploading the files or anything so others can scour through them, but any help figureing out the key would be appreciated

Can't open Files nor Save it... May there is an other Function needed.

Console doesn't log any errors/warnings

decrypter creates non-working PNG files that cannot be opened
