Image Diffusor added.

@Keya
People also often look for simple solutions.
It's nice to be able to say, look, here's something for you, try this.
Whether the NSA can crack it or a horde of crackers gets their hands on it is usually irrelevant.
All games have been cracked so far.
But think about it, these are games that were developed at a cost of many millions of dollars.
Who, seriously, is interested in a small game written with PB ?

Security relevant software is also usually created with software that has been tested and analyzed thousands or millions of times.
People can get ideas here, but hardly anyone will be so bold as to say that he got his security tools from a forum and then use them in the operating software of a nuclear power plant.

Even the much-cited hospital software, with the highest security standards available, is unlikely to be created much differently.
Whether this software is then programmed in a basic dialect, with various self-created tools or tools from forums, I leave to your imagination.

A tiny bug or a thinking error in a security software, can undermine it completely.
Who is then liable for the damage ?
This stuff must have been tested many thousands of times.
How many views do we have here on average in a thread ?

How many professionals use what we create in security relevant software at all ?

What professional security software for above mentioned institutions have you already created with PB ?
List them, show some shots !
Give us a glimpse into a requirements and specifications document from one of your professional projects.

It simply misses the point of reality.

So creative criticism is always welcome, but it should not be based on knowledge gaps or bashing.

Hello SAKI

I'm not enough intelligent for know if your crypter is safe
But i can say to you the three codes works here

The "Diffusor" version not hide really the picture



But the two others yes

AES method



Simple method



Thanks for sharing

Diffusor with AES added.

Hi Kwai,
thank you for your test and that you like it.

It's all OK, pewing venom is just bashing to try to make things bad across the board.

The diffuser is intended to damage the images only to the extent that no one can steal them to use them themselves.
They are then worthless because they are completely pixelated.
But you can still see the contents.
This makes it easy to manage many images in one software without anyone being able to steal them.
You don't have to use the names of the images or textures yourself.
So you can easily exchange certain images, because you can still see what it is.

Best Regards Saki

I'm confused. You say the diffusor is about leaving the image somewhat viewable, but now youve added AES to it (which renders the image unviewable) - but you've already got an AES version - so can you elaborate what's the difference between the AES version and the AES diffusor version? Thankyou

Hi saki... I really like this...

for me the "WTF" Part is the RandomSeed. I didn't know that, if you set the Seed, every Random number will be the same. This is soooo cool.

And I learned something. For me, I use One-Time-Pad. (The best encryption, ever. Never hacked, cracked, wordlisted or brute-forced) So I changed some of my code.

Thx for the Idea and for the code.

BTW... I prefer her without that hairstyle

Hi @Cyllceaux.

I am glad that you like it.

You can also take the variant with AES.
If you look at this, you will see that you can also insert this small part into your code, just like the RandomSeed.
The encoders and decoders differ only by a plus or a minus sign.
You have to take care that you don't mix up anything, because this is hardly noticeable.

Yes, the lady looks very pretty.
It's amazing how the hairstyle alone changes her.

@Keya
The AES version of the diffuser works exactly the same as the diffuser version without AES.
Both versions pixelate 33% of the image content, so the image remains visible with both.
Just try it, even with AES it is possible to manipulate only a part of the image.

Best Regards Saki

Cool! Sorry I misunderstood. It's an interesting approach leaving the images visible to the developer, yet distorted enough they're useless to attackers/thieves in that state. (Although of course they can still be dumped after decryption, but nobody can really stop that, as Hollywood knows). And Im glad you switched to AES instead of Random()

Yeees !!! very good and usefull idea !!!
Thanks a lot for your kind explanation, and also for your great code

You have right, this hairdresser make miracles

@Kwai
Many thanks for your testing again.

But that was not a hairdresser, that is a wig, but not a cheap one.

If you're wondering what a cheap wig looks like ...


It's a wig! https://www.youtube.com/watch?v=UfJZ9pfnF70
