Ok, so I'm not all that great with assembly but with intelisense came across the option to put in a AssemblyHashAlgorithm line using md5, sha1, or none in AssemblyInfo.vb. Does this actually protect your application with the chosen algorithm? I'm in the market for an easy to use tool otherwise that can take an executible and encrypt its contents so it still can be used but at the same time protect against reverse enginerring like Chris has shown on a .net app in a past hak5 episode.
So if you had an award winning app you wanted to protect, what would you use?
Perhaps this would be a good follow up to the episodes on how to break it, versus showing us how to protect against it...

Setup a bat to run it and than the browser you want to browse the net with and either scheudle/click when needed.

And word is they may be changing it to update for Vista and Server 2008.
They probably already have or well by the time you get to your 7th exam :( And its really 7k? A single exams 1k?

A fellow class mate has already passed CCNA (he is currently on his last CCNP exam) and he managed to do CCNA in 4 months, but he is asian after all and spent every hour of every day working at it.
4 months sounds about right if you want to cram it and hope you get a score good enough to the pass the minimum. Thats about how long I spent for my net+ and sec+. Though I passed it, I must admit I wasn't very satisfied with my score on the net+ test. Than again, I took net+ and sec+ on the same day within 3 hours, so I had been studying for two certs at once, spending about 2-3 hours a day on weekdays and maybe a little longer on weekends until I finally broke down and scheduled.

I just finished my exam earlier today, and passed! Passing score for the 2009 edition is 720/900. I obtained a 860/900, which I did much better on this than the A+ cert.
Thought they had raised the passing mark...
Anyway, congrats tobar! Its so heart pounding as you sit there doing thier little survey just to get your score but I know exactly how great it feels when you see a passing mark on the screen for a test you've studied hard for. What cert you going after next? CCNA? I think I'm going to work on Linux+ and possibly Server+, since I've already done A+ and Sec+. Than I'm probably done with CompTIA and on to the cisco stuff with the rest of you networking guys here.

Bottom of index page... most forums have 'em.

Network+ isn't easy, but it is an entry network exam. Thier passing requirements for the exam however are slightly lower (at least they were with the 2007 exam I took - 554 or better to get a passing mark) I recently got mine. Expect to see a lot of material on network troubleshooting, the osi model, and subnetting. Above all use common sense and proccess of elimination. Network+ is nice cause its one of thoses certs that doesn't expire.
@digip, you should take the net+ exam first. CCNA material is the slightly more advanced networking cert I'd imagine. If you can get your CCNA you should have no trouble with net+.

How disturbing. Looks like the guy can barely get off the couch. Linux user it must be than.

OMG! Is that the first BSOD EVR in the background?! :P
BSOD 1.0 rofl
Nice pics everyone, choose a better thread title next time though lol

So I must use a char array and cycle through it to compose strings? Or would this do?...
char *a = "some text";
Where whenever I refer to *a in code it would return its string literal?
Edit: ok, I guess you just use the function there to assign it. Thanks.

Well I found hak5 when it came to Revision3 like my profile says...
Little did I know i'd spend a good couple of days watching every episode :) I like hak5 because it is a video podcast where most of the time with the good IT sec podcasts out there all you get is audio and you lose track of what thier talking about quite easily while you're trying to multitask.
-
Freeb, how would you do a string variable in C anyway?
string variablename = "some text"; ?
-
Sorry, I'm not good with C, but what I did in VB was...
Make two arrays. One full of random numbers and the other with the actual information the application needs to use. Don't know about C but VB has a Array.Sort method that I use to sort the random array as the "key value", providing the second array as a second parameter, which well also sort that array's elements based on how the first array is sorted.
Hopefully that'll steer you into the right direction...

What does a 3 year old do with a computer?...
At some point you realize the age of child and the use of computers during that stage in thier life isn't a good idea.
-
I like reading on the computer more because I dont haft to hold a book. Just sit and read. Don't really highlight stuff, but at least with the computerized version you can copy/paste into a notes doc to keep track of the material.
Desktops in every classroom with the bare minimum and exercises pre-loaded either on the computers locally or on a network share. No laptops. Too much trouble like said and since the students can use them for personal uses all of the stuff they use in their free time is available to them during school time. With locked down desktops, there wouldn't be.
With desktops in every classroom, there would be less need for computer labs as well, though one or two may still be useful for the occasional project.

Episode 5x05
in Hak5
Great episode, though I'll be doing a lot of pausing to get down commands and figure out what 0x... is used for. What an adorable little monkey though. The cartoon one during the video kept me entertained :)

Looks fine to me. If its not working properly or giving you errors insert a double of the problem character. That tells VB you want the actual character to be printed, rather than caring out an action on it.
In addition, you may want to create a new line like actual html code would appear like in say something like notepad, so it appears like this:
<html>
<head>
</head>
<body>
<p>Some Text to Display</p>
</body>
</html>
To do this, use a rich textbox control or enable an existing textbox control's multiline property. Append VB's vbNewLine command wherever you want a return to occur, like this:
TextBox1.Text = "<html>" & vbNewLine & "<head>" & vbNewLine & "</head>" & vbNewLine.... and so on.

I kind of understand your explaination, but want to know what its doing behind the scenes detail by detail, command by command...
Questions:
Whats the /f swtich for for "for"?
How can diskpart run without /s for "list volume" which is echoed before it without using a file?
Whats the ' for before "echo"?
I guess its incrementing v<number> variables for each volume line returned using findstr on the output from diskpart list volme, but what are the ^'s for?
-
I've made up a couple batch files in my day. I'm familar with %1 %2 %3 etc for passed in parameters. Its the %v1 %v2 etc and the first two lines that are throwing me off.
-
Alright so with commands like diskpart I've wondered how you could create a batch file to preform actions with x command. I know you couldn't just put say something like "list disk" right after diskpart in the actual batch, so I did end up finding a few sites on google on the topic. Here's a sample batch I'm having some trouble understanding fully. It basically takes two partitions by number as referenced with diskpart's list part command and switches thier drive letter assignments with each other. Not really useful and not exactly what I want/need, but anyway...
@for /f "tokens=3" %%x in ('echo list volume ^| diskpart ^| findstr /c:"Volume %1"') do set v1=%%x @for /f "tokens=3" %%x in ('echo list volume ^| diskpart ^| findstr /c:"Volume %2"') do set v2=%%x echo select volume %1 > SwitchDisks.csp echo remove letter %v1% noerr >> SwitchDisks.csp echo select volume %2 >> SwitchDisks.csp echo remove letter %v2% noerr >> SwitchDisks.csp echo select volume %1 >> SwitchDisks.csp echo assign letter %v2% >> SwitchDisks.csp echo select volume %2 >> SwitchDisks.csp echo assign letter %v1% >> SwitchDisks.csp diskpart /s SwitchDisks.csp del SwitchDisks.cspI know that its echoing all the actions to preform inside diskpart to another file to use with diskpart's script switch (/s). Lines 1 and 2 are what I really don't get and things like %v1, %v2, etc though. Explaination any one?

What is with people apologizing for double/triple posting? I see it all the time here. I believe you can delete your own posts, so why not do that instead of posting yet again with an apology and leaving the orginal duplicates to what you're trying to get across in the topic?
Edit: Nevermind I guess you cant on this forum, but stilll, how do you get to the point of double/triple posting something in the first place?
Reverse Engineering Prevention
in Applications & Coding
Posted
Drop, thanks for your feedback. Those tools look great for if I ever want to go into professional development. Thing is, I don't need licensing or key systems right now and the pricing on some of those tools are ridicuous for a single developer, just a simple solution to safeguard against reverse engineering to easily get access to the orginal source code.
Zimmer, I'm actually interested in putting built-in validation in the application, but I havent been programming long enough to know how to implement it :(
