Programming: Encrypt a file using XOR.

[eddylolz]

How do you reverse XOR Encryption in C programming? key--? 

[TheMasamura112]

INCREDIBLY AWESOME!!! NICE PROGRAMMER YOU ARE!!! I WANT TO HAVE SOMEDAY THE KNOWLEDGE YOU HAVE!!!! AWESMOE SIMPLE BUT BRILLIANT!

By the way... How come does the Crypt.exe knows the secret command, if you didn't declare it nowhere in the source?!?!? how you did that!

[CiphersSon]

Thank you.

[francesco149]

I love the way you create file via CMD, also i love how you say "key"!

[allangfreitas]

this source code do not compile!!!!

Criptacao.c:26: error: expected ‘)’ before ‘{’ token

Criptacao.c:32: error: expected expression before ‘}’ token

thanks...

GOOD JOB

[blackknight509]

Please be more articulate. hard to understand what you're saying.

good vid besides so

You should note that this XOR trick is by no means proper "encryption"; it can only serve as obfuscation.

[nicka1011]

@racerfanracerfan In cryptography, encryption is the process of transforming information (referred to as plaintext) using an algorithm (called cipher) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key.

from wikipedia

so this is encryption, that is unless u hav some secret definition

[Estonian00]

Very nice tutorial. Plain and simple :-)

[DaRkaHT]

this is valid for encrypt trojans?

[MouthofSaurons]

Please move the cursor away from the text! its very hard to read some of the text!

[iEleventyfour]

@MouthofSaurons lol i think ita too late LOL

[johnbstroud]

this example or XOR encryption works with GCC in ubuntu linux .. :)

[ChaperonNoir]

Pure notepad/console, that's how it should be! Focus on the binary!!!!!!

[Goastumos]

very good!

[TheFallibleFiend]

I used to assign XOR encryption for project work for some of my beginning programming classes.

[coreymedo]

great example hakim! i always look forward to your videos!

Very interesting tutorial. :) Haven't seen one from you for quite a while now.
