[Source][VB.Net]Asymetric RSA encryption example - pr0t0typ3 - Oct 20, 2010
Asymetric RSA Encryption Example
Hey Today I gonna show you a little snippet I wrote to show you the usage of the RSA-Encryption which is included in the .net Framework.
This Encryption is a kind of different to almost everything you saw before.
It works with two keys. One you can make public that can only encrypt Text/Files/smth. else. And one key you should keep private as only this key can decrypt the encrypted data/text.
The special and very very good thing about that is, that you don't need a key exchange.
That means that if you make a RAT for example and the Victim is able to sniff the traffic he'll only get the encryption key which will not make it possible to decrypt the sending/sent data/text.

So here are the positive things about this encryption example:
- Secure (As much bit as you want (I used 512))
- Asymetric (no keyexchange needed)
And here you go:

Awesome code :)
so this can go up to 1024 bits as well ?
* - iDope -.- - Oct 20, 2010
Going to go through the source now.
Thanks for this, looks like it'll help me somewhere.
* - The-Noob - Oct 20, 2010
very nice. I'm trying to learn about encryption and such :)

You can go up to 10240 if you want ^^ as high as you want but it will become very slow and 512 shold be enought

thanks add this in my crypter/binder
many thanks .

No Problem..
I don't know if it is a good idea for a crypter as it is mainly used for very secure data (CIA and M16 are also using it) and a Crypter just needs to be undetected.
I would sugesst it for a RAT as I already mentioned above.

Wow nice :) First metric RSA encryption seen here.
* - Times Change - Oct 20, 2010
Thanks, I will be using this to actually understand the encryption and probably try and make my own crypter.

No Problem.. Thanks for the feedback and @above I already said that I guess this is not the best encryption you could use for a crypter .. Maybe a HWID/Login System would be nice using this

Not trying to jack the thread or anything, just providing another resource for this. As Prototype has mentioned, you definitely do NOT want to use this for a crypter - it should be limited to small amounts of data (128 to 1,024 bytes).
* - pr0t0typ3 - Oct 20, 2010
Ah well I didn't see your thread but it is a kind of similar to my usage good work and yeah you should not use it in a crypter
* - c6p0 - Oct 20, 2010
these possible to divide the server into several parts so that each party is encrypted independently.
* - 6e756c6c - Oct 20, 2010
No, Asymmetric encryption is intended to transfer a key so that said key can be used as a Symmetric encryption key. Never use it on large amounts of data.

ok thanks sir
just for little server like downloader .
